RISC-V Phone

The goal of the "RISC-V Phone" project is to develop a simple, fully featured and privacy enhanced mobile phone. It is built using off-the-shelf inexpensive components which are easy to assemble even in a home lab. The software for it is small, simple and easy to audit. Basic phone functionality is running on a secure RISC-V microcontroller (FE310 from SiFive) which controls all peripherals: microphone, speaker, display/touch controller, camera. The phone will be using esp32 for WiFi and Bluetooth, along with industry standard mPCIe modem for cellular communication. Graphics/touch panel controller FT813 enables advanced user experience. The phone will provide VOIP/messaging application using packet data protocol similar to CurveCP which features end-to-end encryption and onion routing. There is also a socket for optional ARM SoM which shares display/touch panel with the main board.
