Mediatek Labs has announced LinkIt Smart 7688 development boards powered by Mediatek MT7688 WiSoC earlier today, but I was selected for a close beta several weeks before the launch, and I’ve had time to play a little with the boards, so today I’ll report my experience getting started with LinkIt Smart 7688 amd 7688 Duo by writing a Quick Start Guide showing how to setup the boards, upgrade firmware, access the serial console, run “Blink LED” sample applications with Python and JavaScript, as well as the Arduino IDE, and connect to the Internet. Initial Setup You’ll only need a micro USB cable and a computer with WiFi and USB ports to get started with the board. The green LED (top) for the MCU will turn on immediately, while the red LED (bottom) for WiFI will blink once, and only turn on continuously after 5 seconds, and within 30 seconds after […]
Mediatek LinkIt Smart 7688 and Smart 7688 DUO Boards Run OpenWRT for IoT Applications
MediaTek LinkIt is a collection of development platforms designed for the prototyping of wearables and Internet of Things (IoT) devices, and last year they started with LinkIt ONE board based on Mediatek MT2501 “Aster” micro-controller and featuring WiFi, Bluetooth, GPSD and GSM/GPRS connectivity. Mediatek Labs has now launched two new LinkIt board, namely LinkIt Smart 7688 and LinkIt Smart 7688 DUO, both powered by Mediatek MT7688 MIPS processor and running OpenWRT, with the latter also adding an Atmel ATmega32U4 for Arduino compatibility. LinkIt Smart 7688 Board LinkIt Smart 7688 is then the simpler of the two with the following specifications: Processor – Mediatek MT7688AN MIPS24KEc processor @ 580 MHz with WiFi System Memory – 128MB DDR2 RAM. Storage – 32MB flash + micro SD slot Connectivity – 1T1R Wi-Fi 802.11 b/g/n with chip antenna and I-PEX conector USB – 1x micro USB host port, 1x micro USB port for power […]
MIPS Creator Ci40 Development Board Powered by cXT200 SoC Launched for $53 on Kickstarter
Last year, Imagination Technologies launched their first community development board with MIPS Creator CI20 powered by Ingenic JZ4780 dual core MIPS processor running both Android and Linux, and now supported by various projects. The company has been teasing about its MIPS Creatort Ci40 for a few weeks, and was already announced as the MIPS platform of choice for Google Brillo operating system, but the board has now officially been launched via a Kickstarter campaign where you can get the board for $53, as well as some add-on boards. But instead of using a processor from one of their partner, Imagination just designed their own MIPS interAptiv SoC for the board. Creator Ci40 board specifications: SoC – Imagination Technologies Creator cXT200 with 2x MIPS interAptiv core @ 550MHz, 512KB L2 cache, and an Ensigma C4500 RPU (for 802.11ac/ BT 4.1 LE) System Memory – 256 MB DDR3 Storage – 512 MB […]
How to Build Brillo Operating System from Source Code and Run Brillo Emulator
Google formally launched Brillo operating system a few weeks ago. The new operating system is a stripped down version of Android that targets Internet of Things (IoT) applications, and more recently the company pushed the source code to their servers. So I’ve given it a try by checking out the code, building Brillo emulator for Intel/AMD, and running it in Ubuntu 14.04 64-bit. First you’ll need to retrieve the source code:
1 2 3 4 |
mkdir brillo-master cd brillo-master repo init -u https://android.googlesource.com/brillo/manifest -b master repo sync -j8 |
It took a few hours here with some errors the first time, so I tried again and I finally got the code a few hours later. Once this is done, set the build environment and configuration:
1 |
source build/envsetup.sh && lunch |
Lunch will bring a list of possible builds:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
You're building on Linux Lunch menu... pick a combo: 1. aosp_arm-eng 2. aosp_arm64-eng 3. aosp_mips-eng 4. aosp_mips64-eng 5. aosp_x86-eng 6. aosp_x86_64-eng 7. brilloemulator_arm64-eng 8. brilloemulator_arm-eng 9. brilloemulator_x86_64-eng 10. brilloemulator_x86-eng 11. edison-eng 12. mini_emulator_arm64-userdebug 13. m_e_arm-userdebug 14. mini_emulator_x86_64-userdebug 15. mini_emulator_x86-userdebug 16. brillo_gpios-userdebug 17. brillo_i2c-userdebug 18. brillo_leds-userdebug 19. ledflasher-userdebug Which would you like? [aosp_arm-eng] 9 |
You could also run the “Brillo emulator” on ARM, and edison-eng must be the build for Intel Edison board. Now you can start the build:
1 |
make -j8 |
It has to complete 21491 different tasks, […]
RedBear Duo is a Breadboard-friendly Wi-Fi + BLE IoT Board Based on Ampak AP6212 Module (Crowdfunding)
I’ve taken apart lots of TV boxes and together with Realtek, Ampak are by far the most popular wireless modules to provide WiFi and Bluetooth connectivity in those devices. One startup decided to use Ampak AP6212 module, also found in NanoPi 2 board, to create a breadboard-friendly IoT board with Bluetooth 4.0 and 802.11b/g/n connectivity. Redboard Duo has been designed with the same form factor as many other IoT boards such as NodeMCU or Spark Photon, and features the following: Ampak AP6212 module: STMicroelectronics STM32F205 ARM Cortex-M3 @120MHz, 128 KB SRAM and 1MB Flash Broadcom BCM43438 Wi-Fi 802.11n (2.4GHz only) + Bluetooth 4.1 (Dual Mode) combo chip Storage – On-board 16 Mbit (2 MB) SPI Flash Integrated chip antenna with the option to connect external antenna Expansion – Headers with 18 I/O pins Misc – RGB status LED Dimensions – 20.5mm x 39mm The company also made a small baseboard called RBLink with […]

AndroMeda Box Edge Brillo Starter Board Features Marvell IAP140 Processor, 96Boards Form Factor
Google announced Brillo, a new operating system based on Android and targeting the Internet of things, at the end of October. The company also disclosed that ARM, MIPS and x86 architectures were supported via respectively TechNexion Pico-i.MX6UL system-on-module and PICO-DWARF baseboard, MIPS Creator CI-40 board, and Intel Edison development board. A few days later, Marvell announced Andromeda Box, an IoT platform supporting Brillo and Weave, based on IAP140, a quad-core ARM Cortex A53 application processor for the “Edge” version, and ARMADA 385 dual core Cortex A9 processor for the “Connect” version, but without the full details. AndroidMeda Box Edge is now listed on Solid Run and Arrow websites, where it is sold for $74.99. If the board looks familiar, it’s because it clearly follows 96Boards form factor, but instead of officially being supported by Linaro, it has been designed specifically as a Google’s Brillo development platform with the following specifications: […]
Newracom NRC6101 802.11ah WiFi SoC Promises up to 1 km Range for Smart Grid and Automation
802.11ah is a new WiFi standard operating in the 900 MHz range that targets low power & long range connectivity, as required by many IoT & M2M applications. According to this low power WAN standards comparison table, 802.11ah also supports up 1km range outdoor, 150 Kbps to 346 Mbps transfer rates, up 8191 clients per access points, and a 2016 launch is planned. However, I had not seen any implementations based on the new standard, except a demonstration by Antcor on a DSP in 2014. A Korean startup, Newracom, may however soon launch the first 802.11ah chip with NRC6101 SoC. I was tipped about this new solution via a Korean website, where I got the picture above from, but there’s no information about NRC6101 on the web, except for a small mention on Wikidevi.com redirecting to the product page, where NRC6101 name is not even mentioned, but with some specifications […]
