Las month, Olimex discovered a Chinese company called GigaDevice has made an STM32 clone called GD32 and compatible with STM32F103, but with higher core frequency (108MHz). Olimex has now posted an update after receiving a letter from GigaDevice, and trying GD32F103RBT6 MCU on their own STM32F103 boards. The company explained that GD32 was their own implementation, and claimed rights on GD32 trademarks, while Olimex discovered than GD32 was working just fine on their board having passed “all functional tests without any modifications”, and with all the same development tools and software code running fine. GD32F103xx datasheet (PDF / English version) can be downloaded to find a few more details: The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. […]
FTDI NerO is an Energy Efficient Arduino UNO Compatible Board That Can Handle Higher Loads (Crowdfunding)
FTDI found out that the original Arduino UNO R3 boards had issues handling higher loads with 9V and 12V power input being limited to about 800mA and 300mA respectively before the voltage of the 5V regulator drops, so they decided to make their own supporting up to 1A.

Quick Start Guide for LinkIt Smart 7688 (Duo) Board
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.
