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 …

Have you ever found a base-board for one of these? I've found the double row of pins makes for very difficult prototyping.

No and I agree with you it is not breadboard friendly or suitable. I plan to design a breakout PCB when I have some spare time.

I guess you could solder the outside pins downward as normal, and the inside upward and use female to male jumpers to connect to the breadboard.

That's a brilliant idea - why didn't I think of that? I'll solder one today and see how it works. [trial_A] [trial_B]

It must be my positronic brain :rofl: :rofl: :rofl:

I have just ordered a handful from AliExpress. I am hoping to use them with node-red-mcu-plugin. I have been using D1 Minis, but they can only cope with a very few node red nodes. Not surprisingly.

That sounds interesting, although for me there is a limit as to how many projects I can handle at once - I think it's called "bandwidth". I've decided to try using Micropython for the last set of S2s I bought from AE.

[image] dynamicdave: a limit to how many projects I can handle at once Have you seen the Brachiograph in the Raspberry Pi blog today Dave? A pen plotter from 2 lollipop sticks, 3 servos and a Pi zero. It looks great fun but it's lacking a little something ... A Node-red dashboard perhaps.

Hi Dave, I am glad you get your devices working. Although I have had mine for a week or two I haven't had time to 'play' with them. I prefer to use platformIO over Arduino and I have managed to load a basic sketch that blinks the LED. For the life of me I cannot get the serial to work, when I con…

Hi Bob, I've used Thonny 4.0.2 for my initial experiments with the ESP32-S2 Mini. https://thonny.org/ I reflashed the devices I received from China with the latest version of Micro-Python. There is an option to help you do this when you click the 'Configure interpreter' button/option. I can just…

S2 Mini based on ESP32-S2 with the same footprint as the Wemos D1 Mini

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.
