## Description

Your new RP2350-powered, connected desktop companion! Features a 4" square touchscreen, elegant black aluminium stand and RGB backlighting.

Presto is a swish, fully programmable display designed to keep precious digital information close to your fingertips. Make it do anything you want...

Calendar updates? Check.

Weather reports? Sure!

Photos of favourite humans or animals? Of course.

Generative digital art? It would be rude not to.

It features a tasty, full colour **4" square touchscreen IPS display**, with all the power of Raspberry Pi's new RP2350 chip behind it. Also behind it is some sweet 7 zone **RGB backlighting**, a **piezo speaker** for alert boops, an **SD card slot** for adding storage and a **battery connector**, so you can power Presto without having it tethered to USB. It also has a built-in RM2 wireless module for 2.4GHz **wireless connectivity**.

**Getting Started**

Presto comes pre-loaded with MicroPython, the Presto launcher and some examples, but you can find the most recent version of the firmware and more examples below:

- [Presto MicroPython firmware and examples](https://github.com/pimoroni/presto)
 
There's also a boilerplate project for if you'd prefer to program your Presto with C++.

- [Presto C++ boilerplate](https://github.com/pimoroni/presto-boilerplate)
 
**Connecting Breakouts**

Presto has a Qw/ST (AKA Qwiic/STEMMA QT) connector, so you can connect up Qw/ST breakouts easily using a [JST-SH to JST-SH cable.](https://core-electronics.com.au/piicodev.html#category_1309)

- [View everything Qw/ST!](https://core-electronics.com.au/catalogsearch/result/?order=bestsellers&q=qwiic+stemma+piicodev)
- [Breakouts currently compatible with our C++/MicroPython build](https://github.com/pimoroni/pimoroni-pico#breakouts)
 
**Notes**

- Measurements: 110mm x 92mm x 80mm (H x W x D, approx)
- Note that Presto has no battery charging hardware onboard - this is so you can use either alkaline or LiPo batteries safely. You'll need to charge up your LiPo battery with a separate battery charger (we like [LiPo Amigo](https://core-electronics.com.au/lipo-amigo-lipoliion-battery-charger-lipo-amigo.html)).
- The battery connector can be used to power Presto with batteries that provide between 3V and 5.5V. At the lower end of that voltage range, you'll start to see dimming of the backlight and less vibrant colours. We'd suggest using a [LiPo](https://core-electronics.com.au/power-batteries.html#category_307), or a [3x AA alkaline battery pack](https://core-electronics.com.au/aa-3-battery-box-with-switch.html) - check out the extras for some options.
