Product Description
Variant: RP2350-Touch-LCD-3.5.
The RP2350 3.5inch LCD Display Development Board raw display combines an RP2350B with capacitive touch input and integrated audio processing. It supports the development of embedded user interfaces and experiments involving image capture or motion-based control. This version is supplied without a case or camera. GPIO connections, a camera interface and a microSD slot provide expansion paths. Programming uses USB-C, while a 3.7 V lithium battery connector supports charging and discharging. Supported programming environments include C/C++, MicroPython and Arduino.
