Microchip RN2903 LoRa Transceiver Breakout Board

A breakout board for Microchip’s series of LoRa transceiver modules:

  • RN2483 fully-certified 433/868 MHz Module (Europe)
  • RN2903 fully-certified 915 MHz Module (North America, Australia)

The RN2483/RN2903 LoRa modules contain a Microchip PIC18LF46K22 MCU with a Semtech SX1276 radio transceiver and is intended as a complete certified solution with LoRaWAN Class A protocol stack and an ASCII command interface over a UART connection.

However, if you want to get under the hood, MicroChip provide details in the LoRaWAN Library Plug-in for MPLAB Code Configurator User’s Guide on how to target the on-board PIC18LF46K22 and customise the module for your own purposes.

    • Yes, the breakout board will work with RN2483 433/868 MHz Modules. Simply populate the correct antenna for your frequency band.

      You can reprogram the MCU in the module as a stand-a-lone LoRaWAN Node, or you can use an external MCU to command the RN2483.

      • Thank you very much for informing me.I’m a novice with PCBs. I’ll have a few more questions. .I bought the product on this link.

        I’ll have this module in about a week.I’m thinking of using it with Raspberry.Can I install the Ln2483 module by soldering it after printing the pcb in the Gerber file on this page?In summary, only after ordering a pcb with the Gerber here, can I install antenna and lora mode in my house? I’m sorry for my long, novice sentences. I’d be very happy if you could help me. Healthy days. 🙂
