A touchscreen matrix using an 3.5" ILI9488 TFT with resistive touch and a Raspberry Pi Pico

A touchscreen matrix using an 3.5" ILI9488 TFT with resistive touch and a Raspberry Pi Pico. The Raspberry Pi Pico has native HID Keyboard support. This sketch gives you 12 buttons in a 4x3 matrix. Each button can have one or more keyboard functions.

- In the Arduino IDE go to File->Preferences. - Under "Additional Board Manager URLs" add this line: https://github.com/earlephilhower/arduino-pico/releases/download/global/packagerp2040index.json. Click OK. - Go to Tools->Boards->Board Manager. Type "pico" in the search box and click "Install" for "Raspberry Pi Pico/RP2040".

Pico-Matrix-Touch-Keyboard: common questions

What microcontroller does the Pico-Matrix-Touch-Keyboard use?

The Pico-Matrix-Touch-Keyboard is built around the Pico, from the RP2040/RP2350 family.

How big is the Pico-Matrix-Touch-Keyboard PCB?

The Pico-Matrix-Touch-Keyboard measures 98.1 × 55.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pico-Matrix-Touch-Keyboard?

6 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico-Matrix-Touch-Keyboard design files?

From the DustinWatts/Pico-Matrix-Touch-Keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pico-Matrix-Touch-Keyboard design in my own project?

Yes, under the terms of its MIT license, which DustinWatts chose for the repository.

Can I test firmware for the Pico-Matrix-Touch-Keyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
