ESP32-C3 Development Board with 0.42-Inch OLED
Add a small on-board display to your next wireless electronics prototype. This ESP32-C3 development board combines Wi-Fi, Bluetooth and a 0.42-inch OLED. It is for makers building and programming compatible microcontroller projects.
- ✅ Show a project readout locally — The on-board OLED gives your program a small display.
- ✅ Prototype wireless functions — Wi-Fi and Bluetooth provide communication options for a suitable programmed project.
- ✅ Keep the core hardware together — The board integrates a display and ceramic antenna.
- ✅ Load your own project code — USB downloading provides a route for programming the board.
A compact core for a display-equipped project
An on-board screen is useful when a prototype needs a local status readout as well as wireless communication. The ESP32-C3 core brings those elements together on one development board, reducing the number of separate core modules to arrange.
This is a programmable development board rather than a ready-made smart device. Firmware, wiring and a suitable power connection are required for the intended project. A USB cable, headers and external sensors are not confirmed as included.
