LinkIt Connect 7681 is a Wi-Fi IoT Board Powered by Mediatek MT7681

January 19th, 2015 2 comments

So it looks like Mediatek has decided to carry on with its Mediatek Labs endeavours, as after launching LinkIt ONE last year, they’re about to introduce LinkIT Connect 7681, a development board with a Mediatek MT7681 based Wi-Fi module, and access to various GPIOs.

LinkIt_Connect_7681LinkIt Connect 7681 HDK (Hardware Development Kit) specifications:

  • SoC – Mediatek MT7681 Andes N9 processor @ 80 MHz with 64KB RAM,
  • Storage – 1MB SPI Flash for firmware
  • Connectivity – Wi-Fi: 802.11 b/g/n for Station mode; 802.11 b/g for AP mode via a MT7681 module by AcSIP
  • Headers – 12-pin header for UART, 5 GPIOs (also usable as software PWM), RESET, and 3.3V/5V/GND; 6-pin header for SPI, 3.3V and GND.
  • USB – 1x micro USB for power and programming/debugging
  • Misc – Reset push-button, 2x UART LEDs
  • Power Supply – On-board 1A 3.3V voltage regulator (can be powered from USB connector)
  • I/O Voltage – 3.3V for GPIO and UART
  • Dimensions – 50 x 31 mm (board); 15 x 18mm (Wi-Fi module)

LinkIt_Connect_7681_Block_Diagram

A Wiki has been setup for the board, and already contains a short overview, and links to hardware files (free registration required), API reference, a developer’s guide, and the SDK for Linux or Windows (Cygwin required). Key features of the SDK include:

  • Libraries for all the MediaTek LinkIt Connect 7681 APIs, including Smart Connection and FOTA firmware updates
  • C-like language
  • Command line compiler, based on Andes Development Kit
  • Firmware upload tool
  • MediaTek Smart Connection app examples for Android and iOS, including source code
  • Example source code such as IoTServer, AT Command Parser, Data Command Parser and X-Modem

 

MT7681 Software Architecture

MT7681 Software Architecture

The board is not available yet, but Mediatek Labs MT7681 page indicates LinkIt Connect should be available early 2015 via Seeed Studio. The price has not been disclosed either, but this looks somewhat similar to WRTnode selling for $25, and the HLK-M30 Starterkit, also based on MT7681 and very similar to LinkIt Connect, sells for $16.32 including shipping and a power supply, so I’d expect the new board to cost between $10 to $20.

Thanks to deets for the tip.

Gemalto Cinterion Concept Board Features 3G Connectivity, Arduino Headers for Secure Java M2M Applications

December 22nd, 2014 No comments

Gemalto is a digital security company providing software solutions, smart cards, and secure modules, and one the largest manufacturer of SIM cards. The company has launched a developer board earlier this year called Cinterion Concept Board with the company’s Cinterion EHS6 M2M Java embedded machine-to-machine (M2M) 3G module, and Arduino compatible headers.

Cinterion_Concept_BoardCinterion Concept Board specifications:

  • 2G/3G M2M Module – Gemalto Cinterion ESH6 with Java ME embedded support
  • Cellular Connectivity
    • GPRS/EDGE Class 12, HSPA, 5 bands 3G, 4 bands 2G.
    • Voice support.
    • On-board antenna (top left side on picture)
    • SIM card holder
  • Expansion
    • Arduino Compatible headers
    • 8 GPIO with level shifters, and corresponding LEDs
  • USB – 1x mini USB port for power, 1x mini USB port for debugging and power
  • Misc – Start on/off, and user buttons, LEDs for serial interface.
  • Power – 5V via either mini USB ports, solder pads for external battery.
  • Dimensions – N/A

The board is programmed using Java ME 3.2, and supports FOTA (Firmware OTA updates).  Unfortunately few details are available, as the company only provides support with the SDK and documentation to people who bought the board. Having said that, one developers provided a quick start guide and close-up pictures of the board in Russian so it can get a better idea of the board interface, and what it is capable of. A video entitled Introduction to Java ME Development with Gemalto Concept Boardexplains how to get started with programming, and makes clear a Windows PC is required for development with Java ME SDK 3.2 and NetBeans 7.x.

A quick demo with a fan shows it’s possible to use to board to start and stop a fan by making a phone call to the board.

The board sells for 99 Euros excluding VAT and shipping via Gemalto distributors. More details can be found on Gemalto’s Cinterion Concept Board page.

Thanks to Nanik for the tip.

e-con Systems Unveils eSOMiMX6 SoM based on μQ7 Form Factor, and Ankaa Development Kit

December 4th, 2014 2 comments

QSeven is one of the many standards for system-on-modules, and it defines both Qseven (Q7) 70x70mm modules, and smaller μQSeven (μQ7) 70x40mm modules. While there are quite a few SoMs following the larger form factor, few modules are based on micro Q7, and e-con Systems eSOMiMX6 has just launched one of these tiny modules with eSOMiMX6 system-on-module powered by Freescale i.MX6 processors, as well the corresponding Ankaa development kit comprised of the SoM and a baseboard.

uQseven_Freescale_i.MX6_SoM

eSOMiMX6 module specifications:

  • SoC – Freescale i.MX6 single, dual or quad Cortex A9 processor @ 800MHz to 1.2 GHz with Vivante GPUs
  •  System Memory – 256MB/512MB (Solo only), 1GB (default), or 2GB (dual/quad only) LVDDR3 RAM
  • Storage – 4GB (default) to 64GB eMMC flash, 2MB SPI NOR flash, and SD/MMC + SATA II  interfaces via MXM connector
  • Display / Video Output:
    • HDMI up to 1920 x 1080
    • Dual channel 24-bit LVDS
    • 24-bit LCD RGB
    • MIPI DSI
  • Camera:
    • 4-lane MIPI-CSI  (2-lane for Solo)
    • 10 bit parallel camera I/F
    • 20-bit parallel camera I/F
  • Connectivity – Optional Gigabit Ethernet controller,  optional module for 802.11 b/g/n Wi-Fi and Bluetooth 4.0 BLE
  • Other I/O accessible via 314-pin MXM connector:
    • USB 2.0 host, USB 2.0 OTG
    • SPDIF audio in and out
    • 2x CAN (FlexCAN)
    • 5x serial UART
    • 3x I2C,  3x PWM, SPI
    • Up to 50x GPIOs
    • PCIe x1 Gen2
  • Power Supply – 3.3V @ 3A
  • Dimensions – 70 x 45mm
  • Temperature Range – Commercial: 0 to 70°C; or Extended: -40 to 85°C

You may have noticed the module size is 70x45mm, and not 70×40 as in Q7 specifications, which is probably why the companies refers to a custom μQseven” form-factor, where they’ve kept the MXM connector, the same mounting holes position, but increased the width of the board. So it should still work with most Q7 baseboards, unless the 5 millimeters extra interfere with your baseboard.

The company provides BSPs for Linux (with bootloader), and Android, with Windows Embedded Compact (WEC) 2013 still in development.

Ankaa Development Kit (Click to Enlarge)

To speed up development, e-con Systems can also provide Ankaa development kit with including eSOMiMX6 Module (eSOMiMX6-CS-P1G-F4G-R1G-WB-E with i,MX6 Solo @ 1GHz, 1GB RAM, 4GB eMMC, Wi-Fi/BT, and Ethernet), Ankaa carrier board, and HDMI cable, a USB to serial port cable, and a 9V power supply. They have both Linux and Android version of the kit, and the latter also adds a 10″ LCD with capacitive touch.

Ports and features available on Ankaa development kit:

  • 314-pin MXM connector for uQ7 SoM
  • Storage – SATA connectors (DATA + Power, not working with Solo SoM),  SD Card slot

Spark Photon is a $19 Hackable IoT Wi-Fi Board

November 14th, 2014 4 comments

Spark Core is a popular Wi-Fi module for the internet of things  with a community of over 20,000 developers, but at $39 it may have started to feel a little expensive compared to the new IoT Wi-Fi modules such as ESP82666 or xWiFi, so the company has unveiled a new Wi-Fi board called Photon that’s smaller, better, and cheaper.

Spark Photon and P0 Module

Spark Photon and P0 Module

Let’s compare Spark Core with the new Spark Photon.

Feature Spark Core Spark Photon
Wi-Fi Support 802.11 b/g 802.11 b/g/n
Wi-Fi Setup Smart Config Soft AP
Wireless Module TI CC3000 Broadcom BCM43362
MCU STM32F103 STM32F205
MCU Speed 72 MHz 120 MHz
Flash Memory 128 KB 1 MB
RAM 20 KB 128 KB
GPIO 18
UART (Serial) Yes
JTAG Yes
I2C Yes
SPI Yes
ADC Yes
DAC No Yes
CAN No Yes
VBAT pin exposed No Yes
Wakeup pin exposed No Yes
Price $39.00 $19.00

So beside slashing the price by 50%, the new board supports 802.11 n, comes with a faster STMicro MCU with more memory, and it adds DAC and CAN interface, as well as access to VBAT and Wakup pins. The Wireless module from Texas Instruments has been replaced by Broadcom BCM43362 module that’s used in products like Nest, LIFX, and more.

They’ll also sell P0 module with Broadcom BCM43362 and STM32F205 as shown in the right of the picture above for $10, and a P1 module with a u.FL connector and an antenna on the board.

Finally the company has launched Spark Dev, a new IDE available for Windows and Mac OS, based on Atom project, which also support Linux based distributions.

Spark Photon can be pre-ordered now for $19 + shipping, with delivery scheduled for March 2015.
