Orchard is a low-power, multi-band radio-connected embedded computing solution. In other words, it's an IoT platform.
Orchard is open source hardware and software.
Orchard is also a supply chain solution. Derivatives of Orchard are meant to be manufactured quickly. As a result, a quick-turn supply chain has been set up in China and it is the foundation of the MIT Media Lab Manufacturing Bootcamp curriculum.
Basic feature set:
- Kinetis-W CPU
- 48 MHz Cortex-M0+
- 128k flash, 16k RAM
- 900 MHz radio with +13dBm transmit power (for long-range applications)
- BLE radio (for short-range, low power connection to IP gateways)
