SparkFun LoRa Gateway - 1-Channel (ESP32) with a LCD

I was wondering how I could add a LCD to this device and display the info that it is receiving from another LoRa device?

What LCD’s would work with this device because I know it only unleashes 3.3 V of power. Plus im unsure how to code the LCD to the ESP32. Any suggestions??

Hello, and thanks for writing!

Any of the three new SerLCD’s we carry will work with the LoRa Gateway

  • - LCD-14072
  • - LCD-14073
  • - LCD-14074

    • There’s no Qwiic connector on the new displays, but you can add one pretty easy with a Qwiic Adapter and a Qwiic cable.

  • - DEV-14495
  • - PRT-14427

    • The attached photo shows how everything should look.

    I don’t have code specifically for the LoRa Gateway, but the I2C example code for the SerLCD should give you some ideas on how to send data to the display.

    Okay thank you! I ordered the parts that I needed. If I am having coding issues can I get help here? My code works, I just need the LCD to display what my serial monitor reads.
