Microchip RN2903A-I/RM098 RF Transceiver Module 902 → 928MHz, 2.1 → 3.6V

The Microchip RN2903 is a low-power long range transceiver module based on wireless LoRa® technology. The module contains an integrated MCU, crystal, EUI-64 node identity, serial EEPROM, RF wireless transceiver with analogue front end and matching circuitry, and is fully-certified for 915 MHz wireless operation. A unique spread spectrum modulation process within the sub-GHz band is utilised to enable long range, low power, and high network capacity. When used with an external host MCU the RN2903 module is suitable for simple long-range sensor and IoT applications.
