The ShaRPiKeebo is a pocked-sized computer kit that features a custom PCB with a 2.7 inch sunlight-readable display, a 56-key thumb keyboard plus D-Pad buttons, and a LoRa radio for long-range wireless communication. It's designed for use with a Raspberry Pi Zero W or Zero 2W. So while you'll need to provide your own Raspberry Pi, the kit gives you the flexibility of picking your processor, among other features.
