“I used Presto to create a clock. This clock features a calendar function, slideshow functionality, and the ability to display pre-set messages.
Development was highly efficient as I implemented it using MicroPython, allowing me to complete the project in a very short time.
Calibrating the clock via WiFi is straightforward, making it easy to maintain accurate time.
The RGB565 colour display offers excellent colour reproduction, and the backlight is bright enough to make it well-suited for displaying photos. Additionally, SanDisk microSD cards (I used a 64GB version) work perfectly without any issues.
The piezoe speaker on th back is ideal for playing the hourly chime, and I have also implemented ambient LED effects on the back to accompany the chime.
The aluminium enclosure is solidly built and looks premium, making the finished application feel almost like a production-level product. Furthermore, the touch panel’s sensitivity is excellent, providing a smooth and responsive user experience.”
“The Presto is a cute device.
It has a feature set that makes it very broadly useful - touchscreen, nice colour screen, tiny speaker, WiFi and bluetooth. Couple that with a straightforward MicroPython library, and you can start running fast - e.g. you could very quickly make a little dashboard that pokes addresses over the local network to change lights, read data, or bring in anything from the internet.
The Qwiic port expands the usefulness. I don't have a killer use for the backward
-facing LEDs yet, but they're a fun idea. The USB port isn't ideally placed, but a right-angle cable can help keep that tidy.
The only unexpected limitation I've found is that two-point touch can misbehave when both are close to the same horizontal line, but otherwise this is nicely rounded! Very happy with mine.”
“A very fine product, in many ways 'just the ticket'. As any design, there are needed extensions. The use of I2C as the external interface and WiFi as the communications medium are, by themselves easy to work with and the Pico2350 is an excellent chip, but some access to the 2350GPIO would have been a nice thought.
One answer is the IIC to Serial converter which works fine for Arduino but I have not been able to make it work on the presto under micropython.
I like the touch colour screen (480x480) and Pimoroni give a good example software set, but I still yearn for some GPIO access.
Great product, proud to own one!”
“The documentation isn't there yet, you'll need to figure out things on your own (hint: it's a pico). Great board though, and the possibilities are huge as a desk gadget, works brilliantly”
