Above all, the Pico-Eval-Board is a full evaluation solution designed for Raspberry Pi Pico. With 3.5inch 65K colorful LCD display in addition to the misc helpful onboard components, this evaluation board allows you to try almost every on-chip peripheral of the RP2040, eliminating the messy wiring. Therefore it is an ideal choice for users to fast get started with the Raspberry Pi Pico, as well as the RP2040 chip.
This board includes
- Standard Raspberry Pi Pico header supports Raspberry Pi Pico series boards
- 3.5inch resistive touch screen, 65K colorful, bringing clear and vivid display effect
- Standard 3.5mm audio jack, therefore you can use headphones or other audio peripherals
- Micro SD card slot through the SDIO interface, faster access speed than SPI interface
- Integrates battery header and recharge circuit, allows it to keep running without wired power supply
- In addition, other rich resources like a buzzer, photoresistor, and RGB LED…

Download Demo codes
Open terminal and run the following command：
wget -P ~/pico/ https://www.waveshare.net/w/upload/f/fc/Pico-ResTouch-LCD-X_X_Code.zip
What can I do with this?
After running the demo code, it first displays some characters, patterns, and then displays pictures, and finally displays the touchpad function.
Therefore, if you need characters of different sizes and fonts, you can use the font extraction software provided in the materials to create your own font library
In fact you can also Image2Lcd picture modulus software to convert images of different sizes different formats to array data, then use our written function display
Above all you can load images off your SD card. For instance you can create fun, interactive games.
The Raspberry Pi Pico is also compatible with micropython, therefore it has never been so easy to write your own code.
Above all, there a tons of libraries and code examples available for you. In other words, the only hard part left is opening your imagination and finding the right project for you.
MicroPython is a software implementation of a programming language largely compatible with Python 3, written in C, that is optimized to run on a microcontroller. It is a full Python compiler and runtime that runs on the microcontroller’s
