I recently decided to increase the number of my Arduino UNO sized boards (not original ones, clones) from a Chinese warehouse, any of them, I’m not fussed.
Imagine my consternation when the board I wanted, a standard UNO format but with a micro USB socket rather than a full sized one were rarer than hen’s teeth. And quite expensive, relatively speaking.
I can remember just a couple of years ago that all the Far East sites were awash with these boards for about $3 ($2.50) each. Now they are around the $6 mark (£5) – if you can find them at all.
There are plenty of Nano-sized boards at very good prices but I wanted a full-sized UNO board! With a micro USB socket!
What I found instead, around the $3 mark, is the UNO sized board with an ESP8266 chip on it. I rejected these at first, as my brain’s filter mechanism was switched on. But it suddenly dawned on me that the UNO ATMEGA328P had been usurped by the ESP8266 – and why not?
It can do everything the UNO can, plus it has the undoubtedly desirable feature of inbuilt wifi. And it’s faster. Quite a bit faster.
OK, the generated, compiled code is considerably bigger, and so takes more time to upload but the actual C++ source code (that we write) is pretty much the same.
It would be a shame to use such a capable board to flash an LED on and off but then an ATMEGA328P is probably pretty bored at doing that too.
Have a look around the Chinese warehouse sites if you don’t believe me – the UNO (with micro USB socket) is dead! Long live the ESP8266!
I’ve (helpfully) included the link below – it’s an affiliate link that might help my YouTube channel. It shows everything under $5 at AliExpress, which should include those elusive UNO-sized boards!
At the time of writing, I’m off to Germany for a few days to see the family and celebrate my brother’s 55th birthday all rolled into one. I’m just worried about this tickle in my throat…
