Sutajio Ko-Usagi’s wiki is the place where you find documentation for open source hardware projects such as Novena laptop or Fernvale IoT board. There’s another IoT board supporting 900 MHz and Bluetooth radios called Orchard.
Orchard board specifications:
- MCU – Kinetis MKW01 ARM Cortex-M0+ MCU @ 48 MHz with 128KB flash, 16KB RAM
- 900 MHz radio with +13dBm transmit power (for long-range applications)
- Bluetooth LE radio (for short-range, low power connection to IP gateways)
- Display – 128×64 OLED
- Sensors – 3-axis Accelerometer, microphone sensor
- Debugging – FTDI serial port header, SWD provisioning & debug header
- Captouch button controller
- WS2812B LED strip driver
- Lithium ion battery solution
- Gas gauge for accurate battery life determination
- Charging solution that can support high-capacity batteries
- Integral 5V boost
The hardware files and ChibiOS 3.0 firmware source code are all available. The board does not appear to be for sale, but instead students taking part of MIT Media Lab Summer Manufacturing Bootcamp, in Shenzhen, China, modify the design, and create their own board and case over a period of 5 weeks so that they learn firmware coding (on a Raspberry Pi 2), electronics and mechanical design, as well as manufacturing thanks to the guides provided in the wiki.
Thanks to Nanik for the tip.
