New devboard: ESP32-S3-Touch-LCD-1.69

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.


Igelbäcken natur reserve

Between Kista and the centre of Stockholm the TBana passes through a nature reserve. This forms a part of the cities green belt, and is marked with a series of paths and cross country tracks, with different colours denoting different distance circuits.

Skansen again

We went to Skansen again when my sister came to visit.

Nyköping

At the end of the road to Skavsta there is the small industrial town of Nyköping, the NYO Skavsta gets its IATA airport code from.

The town itself clearly used to be a major industrial centre, but now it is more of a tourist centre, with the old mills next to the river turned into heritage museums and handcraft shops. Unfortunately I didn’t find the river until after dark so didn’t get to see it properly, so would like to explore it a little more during daylight.

Road to Skavsta

I hired a car to collect A from the airport upon her return recently, it had snowed a little in the few days beforehand, but the roads themselves were clear. The cars here come with spiked tyres, which make quite a racket when theres no snow underwheel.
