ESP32-C3 OLED Development Board

The KEHIPI ESP32-C3 OLED Development Board is a compact IoT edge device built around the ESP32C3FN4/FH4 core. It integrates a 0.42-inch OLED display with a ceramic antenna for WiFi and Bluetooth 0 connectivity. The board includes 4M Flash memory and supports USB download for firmware updates. It targets makers and developers prototyping connected projects.

Check OLED screen mapping before use

The onboard 0.42-inch OLED uses a 12864 resolution with a starting point offset at coordinates 13, 14. This mapping differs from other common 0.42-inch screens. Existing libraries or code written for standard screens will not display correctly without modification. Verify your display driver settings match this specific offset before integrating the board into your project.

Suits makers needing integrated display and radio

This board suits developers who want a single module combining processing, wireless connectivity, and a small status display. It is not for buyers who need a larger screen area for detailed graphics. It is not for projects requiring external antenna connectors for long-range links. It is not for users who cannot adapt display libraries to the unique 13, 14 coordinate offset.

Spurningar um þessa vöru

What comes in the box and do I need to buy a USB cable separately?

The board includes the ESP32-C3 module with 0.42-inch OLED and ceramic antenna; a USB cable for power and programming is not included.

How do I know which ESP32-C3 chip version I am getting?

The board is built on the ESP32C3FN4/FH4 core with 4M Flash, so you receive that specific variant.

What does the 0.42-inch 12864 OLED starting at coordinates 13, 14 mean for my code?

The display uses a non-standard origin (13, 14) instead of 0,0, so graphics libraries must offset drawing by those pixels.
