Touchsy is family of 3.2 inch, 320 x 240 pixel LCD touchscreen displays designed to work with most single-board computers. There are three versions designed for specific hardware platforms and a fourth that’s a breakout board that should work with most other SBCs.
The developer behind Touchsy has launched a Kickstarter crowdfunding campaign with early bird pricing starting at £23 (about $29) and units expected to begin shipping to backers in April, 2023 (if everything goes according to plan).
All Touchsy models feature 3.2 inch LCD displays attached to a small board that with connectors for different types of single-board computers, plus a few extra features like buttons or a buzzer.
There are four versions of the Touchsy display:
- Touchsy HAT is designed to attach to the GPIO pins on a Raspberry Pi board with 2 programmable buttons, a programmable buzzer, and a 5-way joystick
- Touchsy based on Raspberry Pi Pico W has a connector for a Rasperry Pi Pico, a battery port, 4 programmable buttons, and a microSD card reader
- Touchsy based on ESP-32 has similar features to the Raspberry Pi Pico model, but designed for ESP-32 boards
- Touchsy Breakout Board features an 8-bit SPI interface for connecting to other single-board computers and support for 3v3 and 5V power supplies.
Each model is also available with a choice of capacitive touch or resistive touch panels, depending on whether you want a capacitive touchscreen that supports light finger touch input, or a resistive one that requires a firmer press (or the use of a passive stylus, fingernail, or other object).
The developer says that, among other things, you could use Touchsy as a touchscreen controller for cameras or other hardware connected to a single-board computer, or create a DIY PDA or mini-tablet. Just keep in mind that not only are Touchsy displays small, but also fairly low res: there’s only so much you can fit on a 320 x 240 pixel display.
Optional add-ons include a breadboard kit, relay board, a 1.28 inch round LCD HATs, sensors, and even an air quality monitor.
