What is it?

It's a little ESP32 Board. Perfect for controlling or sensing stuff in the real world and sync it to the internet! You can order the board with a built in BME280 Sensor.

Why did you make it?

I wanted a small ESP32 Board which works and doesn't eat your whole time to get it working and find it's issues and quirks.

I've used the CP2102 Serial converter because this is the one, which works the best way to program the ESP32. Even Espressif uses this serial converter on their own dev boards.

What makes it special?

It's small and already features a BME280 Sensor! (If you want and check the option.. :) )

Quality

My goal is to provide the best quality possible. The modules are hand assembled in Switzerland. I test every module prior shipping. This is a free time project from a Nerd, thus it lacks from any certifications and isn't RoHS conform.

Technical Q&A

How big is the PCB?

• 1.15x1.05 inch (29.21x26.72 mm)

How can I power the thing?

• It's designed to get power via the onboard Micro USB Socket. But you can power it too via the white battery connector. It can even measure the voltage on this!

It just doesn't work. What can I do?

• If you have any sort of issue, just contact me. I try to find a solution for every kind of issue. But make sure to include as many information so I have a clue what you're trying to do.

What do I get if I buy one of this?

• You get one module as on the image. Depends on which configuration you chose you get one with or without the sensor.

Is it compatible with my Arduino IDE XYZ?

• It should work with the Arduino for ESP32. But I can't guarantee it due to I'm not using it.
