Description

I have designed another case for OLED.

This time it's slightly larger 2.42 oled. You can easly find it by searching “2.42" OLED SSD1309 128x64” in google.

 

All you need to make it work is: ESP32-C3 supermini board and OLED screen.

Touch sensor TTP223 and 3v flexible led (around 60mm) is optional.

 

More details on how it works and how to assemble on my github:

https://github.com/Keralots/SmallOLED-PCMonitor

 

Print profile contains 2 versions of the case: with small 3v flexible led or no led bar.

Check my other cases for 0.96" and 1.3" oleds! 

1.3" https://makerworld.com/models/2185211

0.96" https://makerworld.com/models/2051935

 

Quick start:

  1. Download: https://github.com/Keralots/SmallOLED-PCMonitor/releases/download/v.1.4.2/firmware-v1.4.2-OLED_0.96inch.bin (0.96" firmware works for 2.42")
  2. Connect ESP32-C3 SuperMini to PC and go to: https://espressif.github.io/esptool-js/
  3. Click Connect, change flash address to: 0x0, choose the file downloaded in step 1, click Program
  4. Disconnect ESP32-C3 and solder 4 wires between OLED and ESP

    5. Case is easy to assemble :)

    Optional: check my Github for LED and touch sensor adding!
