From the project
ISM RF module with LoRa network capability
ISM02A is a telemetry module based on the Semtech SX1262 RF transceiver. This module is widely used in LoRa and other sub-GHz wireless communication applications. It incorporates an RF switch (PE4259) to multiplex RX and TX on a single antenna, making it a compact solution for IoT and telemetry use cases.
The module is typically used as a LoRa device and offers flexible wireless communication for various low-power, long-range applications.
