Notes
Raspberry Pi HAT that combines an SX1262 LoRa radio with an RTL-SDR receiver (RTL2832U and R860 tuner, 100 kHz to 1.74 GHz, HF direct sampling and a software-enabled 5 V bias tee), GNSS and a PCF85063A real-time clock backed by a rechargeable 3 V coin cell. The Raspberry Pi is not included.[1]
- The listing offers SMA or U.FL (IPEX Gen 1) antenna connectors, each with or without a GPS, LoRa and SDR antenna pack.[1]
- The GNSS receiver is a GP-02 module (GPS and BDS).[2]
- A six-position DIP switch connects the GPS backup battery, GPS PPS (GPIO6), GPS reset (GPIO22), GPS enable (GPIO23) and the RTC interrupt (GPIO16), and selects GPS+BDS or GPS+GLONASS mode.[3]
- The USB-C port and rear USB connector are wired to the RTL-SDR, so they cannot serve other USB devices.[4]
The maker lists Raspberry Pi 3B, 4B, 5, CM4, CM5, Zero and Zero 2W as compatible hosts.[1]
