Introducing Project Fin, a carrier board designed for the Raspberry Pi Compute Module 3 Lite.
It’s a carrier board that can run all the software that the Raspberry Pi can run, hardened for field deployment use cases, and adding some of the things we’ve seen our users needing the most. It includes 8/16/32/64 GB of on-board eMMC depending on the model, has dual-band connectivity for both 2.4 and 5GHz WiFi networks, can take an external antenna for WiFi and Bluetooth, and can accept power input from 6v to 30v (or 5v if you power through the HAT) via industrial power connectors.
It also comes with two special features. The first is a microcontroller that has its own Bluetooth radio and can operate without the Compute Module being turned on. This enables the Fin to perform well in real-time and low-power scenarios. The Compute Module, along with its interfaces, can be programmatically shut down and spawned back up via the microcontroller, which can access the RTC chip when the Compute Module is OFF for time-based operations. In addition, the Fin has a mini PCI express slot, which can be used to connect peripherals such as cellular modems. The Fin also has a SIM card slot to make it even easier to connect a cellular modem.
