Single-button keyboard based on ESP32-S3 with color screen

Overview

CircuitPython is used by default. You can also use MicroPython, Arduino. The main features are as follows: - The display part uses a 0.85-inch color screen, 128x128 resolution, and the display content is delicate - The main control board is currently only designed with the esp32s3 version, which supports WiFi, flash memory and large enough RAM to help add more functional scripts - Overall The operation is mainly based on the mechanical shaft buttons in the middle, and the left and right sides of the fuselage are generally used as auxiliary - the keyboard shaft adopts a pluggable design, you can freely choose the silent shaft or other - built-in small speakers, listening to the sound is as simple as that - onboard 6 axes Motion sensor - There is an expansion port on the back of the fuselage - USB Type-C interface - There is a reset button on the bottom - Onboard color LED
