Hi everyone!
I’m trying to use the 7-Segment Serial Display COM-11442 with an ESP32-S3. Has anyone tried this combination before? I’d love to know if it’s expected to work properly.

For reference, I’m using this dev board:
:backhand_index_pointing_right: ESP32-S3-DEV-KIT-N8R8 (Waveshare)

Any tips or experience would be greatly appreciated!

Sure - start with getting the esp32 going Arduino Setup - SparkFun Thing Plus - ESP32-S3 and then move on to the screen guide Using the Serial 7-Segment Display - SparkFun Learn

The main thing you’ll want to ensure is that you have the right board selected in the arduino menu;
“ESP32S3 Dev Module” with the following settings:

  • USB Mode: Hardware CDC and JTAG
  • USB CDC on Boot: Enabled
  • Upload Mode: UART0 / Hardware CDC
  • PSRAM: QSPI PSRAM
