VoCore2 WiFi IoT Module Features Mediatek MT7628AN Processor

May 11th, 2016 7 comments

When Vocore WiFi module launched in 2014 on Indiegogo, it quickly became popular as at the time it was hard to find cost effective and small WiFi modules with GPIOs, and its compact Ethernet dock solution was also a hit. The developer has now been working on VoCore2 for several months, and recently announced a beta testing program.

VoCore2Vocore2 preliminary specifications:

  • SoC – Mediatek MT7628AN MIPS processor @ 580 MHz
  • System Memory –  64 or 128 MB DDR2
  • Storage – 16MB NOR FLASH, 1x SDXC via I/O pins
  • Connectivity – WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak); 2x 10/100M Ethernet interfaces via I/O pins
  • I/Os – About 30 GPIOs multiplexed with 3x UARTs, 1x I2C, 1x I2S, 1x reference clock, 1x USB 2.0, 1x PCIe 1.1, 1x high speed SPI (40Mbps max), 1x SPI slave, 2x hardware PWM
  • Power Supply – Input: 3.6~6.0V; output: 1.8V, 3.3V.
  • Power Consumption – 74mA @ 5V (wifi on, no data transfer); 233mA @ 5V (max speed cpu and wireless)
  • Dimensions –  25×25 mm

Compare to the first version of VoCore, VoCore2 has a faster processor, more memory, a lower power consumption, a better WiFi signal, and more I/Os. While the software (OpenWrt) will be open source, the hardware won’t be.

VoCore2 is eventually expected to sell for $20 + shipping, For the beta program however, the board is sold for $50 including $20 for DHL shipping, and developers who commit patchsets for VoCore2 to openwrt.org will get a $30 refund. While the hardware is now complete, and OpenWrt runs on the board, there are still many bugs to fix, and the final release is expected in two months time. If you have questions, you can head over VoCore2 forums.

Arduino Yún Shield Adds Ethernet and WiFi to Arduino Boards for $50

May 11th, 2016 1 comment

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little more powerful, you could also use IoT modules running OpenWrt such as a $30 WrtNode or $13 LinkIt Smart 7688 both capable of supporting Ethernet with some hacks. But if you’ve been used to Arduino Yun, have a few spare Arduino boards, or simply think the other solutions are just too cheap, Arduino LLC has just launched Arduino/Genuino Yún Shield for $49.90 / 43.90 Euros.Arduino_Yun_Shield Arduino Yún Shield specifications:

  • SoC – Qualcomm Atheros AR9331 MIPS WiSoC @ 400 MHz
  • System Memory – 64 MB DDR2
  • Storage – 16 MB flash
  • Connectivity – 10/100 M and 802.11 b/g/n WiFi
  • USB – 1x USB 2.0 host port
  • Board interfacing – SPI and HW Serial
  • Misc – 5 LEDs (WiFi, Power, Ethernet, Activity and User); Reset shield and config reset buttons
  • Operating Voltage – 3.3V

The shield is compatible with Arduino Uno, Zero, 101, Diecimila, Due, Duemilanove, Leonardo, and Mega2560 boards.

Genuino_Yun_ShieldThe Yún Shield run OpenWrt-Yun and uses the Bridge library just like Arduino Yún board. You can find all details including documentation, hardware design files, and Arduino IDE on Arduino Yún Shield wiki.

LEDE (Linux Embedded Development Environment) Project is a Fork of OpenWrt

May 4th, 2016 9 comments

2016 appears to be the year of splits in open source communities with Kodi losing its main Android developer, LibreELEC being born out of disagreements within OpenELEC community, and now LEDE project, a fork of OpenWrt, has been created because some people are not satisfied with the way the project is managed, and now “includes a significant share of the most active members of the OpenWrt community”.

LEDE_OpenWrt_ForkLEDE, which stands for “Linux Embedded Development Environment” , has three stated goals:

  • Building a great embedded Linux distribution with focus on stability and functionality.
  • Having regular, predictable release cycles coupled with community provided device testing feedback.
  • Establishing transparent decision processes with broad community participation and public meetings.

You can find more on LEDE Project website, and the source code is available on the project’s git server:

Thanks to Zoobab for the tip.

Xiaomi Mi WiFi 3 Router Unboxing, Teardown, and Serial Console

April 20th, 2016 41 comments

Mi WiFi 3 is the new low cost 802.11ac WiFi router by Xiaomi that sells for about $40. GearBest send my one sample for evaluation, and today, I’ve taken some photo of the device and board, and connected the UART pin to see if the serial console was accessible for people who want to try to port OpenWrt for example.

Xiaomi Mi WiFi 3 Unboxing

There’s some information on the package, but everything is in Chinese, except the part about AC1200 meaning it supports up to 867 Mbps with 802.11ac and 300 Mbps using 802.11n.

Xiaomi_Mi_WiFi_3_AC1200_Router_PackageThe router comes with a 12V/1A power supply, and a user’s manual in Chinese only. There’s also a QR code inside the box linking to the Android and iOS apps,  available both in English and Chinese, so actually that one of the few Xiaomi product that should be easy to use outside of China without some hacks.Xiaomi_Mi_WiFi_3_Router_Power_Supply_User_Manual

The router has four external antennas.

Xiaomi_Mi_WiFi_3_RouterThe rear panel features a reset pinhole, a USB port to connect storage, two LAN ports, one WAN port, and the DC jack.

Xiaomi Mi WiFi 3 Router Teardown

First it looks like I only had to pop the bottom of the case with some plastic tool, but then I noticed a screw in the middle was holding it together. So I had to pierce through the sticker with my screwdriver to completely open it.

Xiaomi_Mi_WiFi_3_Router_TeardownI was a bit surprised that they had used such as large enclosure for a small board, but maybe marketing is in play here with bigger is better? [Update: Actually, it’s for the router to avoid falling backward due to the weight of the antennas]

Beside the three GLGNET GSD16002LF 100Mbit magnetics, the main components include Mediatek MT7612EN 802.11a/b/g/n/ac Wi-Fi 2T2R chip, a chip under a small heatsink which must be MT7620A, and NANYA NT5TU64M16HG-AC DDR2 chip (64 MB). You’ll also notice the pin for the serial console are clearly marked on the right side, but more on that below. The two 5GHz antennas are on left, and the two 2.4GHz antennas on the right in the picture above.

The bottom of the board features Spansion S34ML01G100TF100 flash with 128 MB capacity.

Xiaomi MiWiFi 3 Serial Console

I’ve also soldered a 4-pin header on the right side of the board (GND, Tx, Rx, and 3.3V). to check if I could indeed access the serial console with a USB to TTL debugger adapter.

Xiaomi_Mi_WiFi_3_Router_Serial_Console

Then I started minicom with the usual settings (115200 8N1), powered up the board, and I could get the serial log:

For some reasons, I could not access the command line, as Rx did not seem to work. Not exactly sure why yet.

As mentioned in the introduction, GearBest sent the review sample, and you could purchase the router for $34.99 shipped from their website. The router is also sold for less than $40 on Aliexpress, GeekBuying, and probably other e-retailers.

$15 RobinCore WiFi IoT Module Runs OpenWrt, Supports 720p Video Encoding (Crowdfunding)

March 27th, 2016 7 comments

Do you remember VoCore? It was a low cost OpenWrt WiFi IoT module based on Mediatek RT5350 processor, that had a very successful crowdfunding campaign managed by a single developer, and the project is still going strong with VoCore2 being in the works. Another developer had the idea of doing something similar but based on HiSilicon Hi3518 ARM9 processor with more memory and support for 720p video encoding making it suitable for HD drone camera, compact video cameras, and so on. Meet RobinCore.

RobinCoreRobinCore specifications:

  • SoC – Hisilicon Hi3518E ARM926 processor @ 440MHz with H.264 encoder([email protected])
  • System Memory – 64MB DDR2
  • Storage – 16 MB NOR flash
  • Connectivity – 802.11 b/g/n WiFi via Mediatek MT7601U with on-board chip antenna
  • Debugging – micro USB port
  • Expansion – 2x 30-pin 2.0mm pitch through holes with access to 10/100M Ethernet, UART, I2C, SPI, SDIO, ADC, PWM, JTAG and GPIOs
  • Power Support – 5V via micro USB port
  • Dimensions – 33 x 27 mm
RobinCore Pin Assignment

RobinCore Pin Assignment

The board runs OpenWrt 15.05 with Linux 3.18 or HiSilicon Linux SDK with Linux 3.0.8. The developer has already released some binary images and script, as well as documented is progress on RobinCore.org. Source code has not been released, but he plans to submit patch files to OpenWrt trunk  for hi3518e soon. I’ve been told HiSilicon SDK normally costs $10k – at least outside of China-, but the developer confirmed by email that he obtained HiSilicon SDK and documentation from an authorized agent of HiSilicon, and as well as H.264 video library and API. He also claims to be releasing PCB layout, schematics, documents and full source code for U-boot, the Linux Kernel, OpenWrt, and applications such as the RTSP server, and DVR program if the campaign is successful.

RobinCore_RobinCam_RobinMac

Two add-on boards (aka docks) have also been developed:

  • RobinCam board with Omnivision OV9712 HD CMOS sensor and a wide-angle lens
  • RobinMac with 10/100M Ethernet RJ45 port,a microphone and a SD card slot.

As you can see from the picture above both boards can be connected together to RobinCore.

The project has now launched on Indiegogo (fixed funding), where Robin, the developer, aims to raise at least $7,000 to go ahead with production. A $15 pledge should get you RobinCore, $20 RobinCore with RobinMac dock, $25 RobinCore with RobinCam dock, and $30 the board with the two docks. Shipping adds $3 to anywhere in the world, and delivery is planned 2 weeks after the campaign ends, so around June 2016 with a production run for 500 units.

Imagination Releases OpenWrt and LWM2M Stack Source Code for MIPS Creator Ci40 Development Board

March 25th, 2016 No comments

MIPS Creator Ci40 is a development board made by Imagination technology that features the company’s Creator cXT200 “Pistachio” SoC with a dual core MIPS interAptiv processor @ 550MHz and Ensigma C4500 RPU for 802.11ac/ BT 4.1 LE connectivity. The boards are supposed to be shipped to Kickstarter backers in April, but in the meantime, the company has released the source code for OpenWrt distribution as well as LWM2M stack for the board.

MIPS_Creator_Ci40_OpenWrt_LWM2M

OpenWRT source code is available in OpenWrt repo in FlowM2M gitbub account. Building the code for MIPS Creator Ci40 is quite straightforward:

IMG_MIPS_Pistachio

Select IMG MIPS Pistachio in make menuconfig, save the settings, and then run make to build OpenWrt for the board. This will also build the toolchain, so you don’t need to install any before hand.

LWM2M stands for Lightweight Machine to Machine, and is a protocol from the Open Mobile Alliance (OMA) for M2M / IoT device management, which defines the application layer communication protocol between a LWM2M Server and a LWM2M Client running on LWM2M Device. Imagination implementation is called Awa LWM2M. It’s a development suite that provides a number of components and tools.  For example a gateway will run both LWM2M daemon and client, but a sensor node would only run the client, Creator Ci40 board would communicate with sensors over 6LoWPAN using MikroElektronica 6LoWPAN Clicker boards.

You can find the source code and documentation on Awa LWM2M github repo.

Arduino Tian Board Combines Atmel D21 MCU, Atheros AR9342 WiSoC, and CSR8510 Bluetooth 4.0 SoC

March 2nd, 2016 1 comment

Arduino Tian is an update of Arduino Yun board, mainly replacing Atmel ATMega32u4 8-bit MCU and Atheros AR9331 WiSoC with more recent Atmel SAMD21 32-bit Cortex M0 MCU and Atheros AR9342 WiSoC with support for dual band 802.11 b/g/n WiFi, as well as CSR8510 Bluetooth 4.0 SoC.

Arduino_TianArduino Tian specifications:

  • MCU part
    • MCU – Atmel SAMD21G18 ARM Cortex-M0 MCU @ 48 MHz with 256KB flash and 32KB SRAM
    • Digital I/O Pins – 20x GPIOs with 12x PWM and UART
    • Analog Input Pins – 6x 12-bit ADC channels
    • Analog Output Pins – 1x 10-bit DAC
    • DC Current per I/0 – 7mA
    • Operating Voltage – 3.3V
  • “Linux” SoC part
    • SoC – Atheros AR9342 MIPS74Kc processor @ 535 MHz
    • System Memory 64MB DDR2
    • Storage –  16 MB Flash for firmware, 4 GB eMMC Flash for data
    • Connectivity – 10/100M Ethernet, dual band 802.11n 2×2 2.4/5 GHz WiFi, Bluetooth 4.0 + EDR (CSR8510)
    • USB – 1x USB host port
    • Operating Voltage – 3.3V
  • Input Voltage – 5V via micro USB port or 6 to 17V via VIN pin ( for AC/DC adapter or batteries)
  • Dimensions – N/A
  • Temperature Range – Operating: 0°~60°C; storage: ‐10°~60°CArduino_Tian_Description

You can see that all I/Os are connected to the Atmel MCU, and none of Atheros AR9342 GPIOs can be used. Both chips are connected via a USB hub / card reader, also used for the Bluetooth chip, eMMC memory, and USB port, as well as SPI/ICSP and UART via CP2105 USB to dual UART chip (also used to connect to computer for programming the board). Atmel D21 MCU can also turn on/off the Atheros processor using pin32, which can be necessary if you plan to run on batteries.
