A small modular radio to chat with satellites.
- LoRa UHF communication (TX and RX); - Compatible with Raspberry Pi (40-pin header); - Programmed with CircuitPython; - Independent power supply to increase performance; - Dedicated to PROMETHEUS-1 satellite.
For more details on the RFM98 radio module, check the short and detailed datasheets.
A few issues from RPiGS v2 were discovered during testing, which could be fixed in a new iteration (v2.1). These issues are detailed below:
