Description
SX1255 Raspberry Pi RF shield
A minimalistic, cost-effective Raspberry Pi hotspot. The device supports virtually any amateur radio mode, including TETRA, and covers 400-510MHz range. The baseband interface between the RF chip and RPi is I2S (full duplex). The default sample rate is 125kHz.
The design is, of course, open source and available for free on GitHub.
