From time to time I buy myself a little devboard to tinker with, mostly they are ESP32 based these days, there’s a nice ecosystem around them and they work with the Arduino devtools. I’m going to try to record pertinent information about these boards in a place where I can find it again – the internet is a slippery place and things keep moving around and disappearing.
My latest is a ESP32-S3-Touch-LCD-1.69 from Waveshare, I had one with a round screen before, which didn’t work at all, this one has a small square screen similar to those you see on modern cheap ‘smart’ watches. There is no battery, so it isn’t viable as a watch in its own right, but it does have a connector to attach one if you can order one with the right connector. I can’t, it seems.
Waveshare are normally pretty good at documenting their devices:
I don’t have a plan for what to do with this yet – I have been looking for a small screened wifi enabled device, to use as a gauge or readout for some thing, but I’m not sure what yet. I have an epaper device which is suitable for slow moving readouts, not that I’ve found anything to read out yet.
As usual, though, I start out with the demos and examples to make sure I can compile and deploy, it is shipped with the LVGL_Arduino demo installed, and is always reassuring when the shipped software is included as a demo.
All-in-all this is a nice little devboard, but there are still no plans for what to do with it.
