This is a small development board centred around the ESP32-C3FH4 microcontroller, which has a RISC-V 32-bit single-core processor operating at up to 160 MHz. It comes with 400 KB of SRAM, 384 KB of ROM, and 4 MB of Flash memory, giving you plenty of storage and memory for various projects!

The board also has a colourful and vibrant 0.71″ round IPS LCD with a 160 x 160 resolution. It uses the GC9D01 driver and communicates using a 4-wire SPI connection. It supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with an onboard 2.4G ceramic antenna.

A USB Type-C port is available for power supply, data transmission, and program downloading. Additionally, the board has a built-in battery charge management circuit, with a reserved VBAT solder point for connecting an external lithium battery, letting you take it on the go.

This comes in two options: Board Only and With Protective Case. Please choose which one you want before adding it to the cart!
