Apologies to everyone as this post is not directly related to Node-RED. I know many people on the Forum use the Wemos D1 Mini in their projects to collect data and send it to Node-RED via MQTT, so you may be interested in hearing about this device... This is one example (click the purple coloured …

Finally, had some spare time to solder some pins and headers onto a ESP32-S2 Mini. Then to see if it worked... lashed up a SSD1306 OLED panel driven via the I2C bus. [S2_soldered]

I think it varies where in the world you live. Typically it takes a couple of weeks to get stuff from Ali to the UK. I prefer to use Amazon or Ebay sources if the mark up isn't too great. Where the Ebay price is 3x the Ali price then I think there is an element of greed at play.

Banggood is also good for some larger items as they have EU & UK warehouses. You have to pick and choose though between all of them depending on what you are trying to get. Sometimes larger items can be cheaper from UK shops. I was looking for a Type 2 e-car charging cable recently and Halfords and…

Wow! BangGood USA charges $13.99 for one yes one and a shipping charge of $4.99 for a total of $19.25 and it ships from China and the estimated arrival is between March 18th-28th Aliexpress would cost $1.80 with $2.18 shipping total $3.98 arrival estimated April 26. or I could order 5 for $10.23 …

It certainly is the case that one needs to shop around. I don't go into towns much and so travelling costs are a factor and Screwfix has a minimum order of £50.00 for delivery. All have to weighed up to get the true cost of the purchase. Amazon definitely are not always the cheapest for sure, but…

I've taken your lead Bob and ordered a set of four S2 Mini devices for a total (UK) price of £10.51 The spec says they come pre-flashed with Micro-Python, so that will be a lot of "fun" for just over a tenner. [S2_Mini]

Well that is very easy to explain... On the AE website there are a number of options you can select. [selection] I think I've ordered the right one. Only time will tell. The line-item-title says "S2 Mini", so should be correct.

Color option ? Let’s wait and see.

I didn't order mine from that site, I did a search on Ali for ESP32 S2 and ordered at the best price, with good reviews, that I could find. I have never used uPython or much Python at all, so it might be an interesting learning curve if mine are flashed with uPython. I do most of my programming us…

Micropython is really a breath of fresh air, the REPL interface is amazing, realtime coding on your ESP (over wifi!), no more compiling at the cost of speed, then again how much speed do you need :wink:

Why does it call itself an ESP8266 then ?
