Purchased in early 2023 for the implementation of various small projects. For the price I bought it (€7), it was an amazing value for money, very good hardware, built-in wifi & bluetooth, and the pinout didn't require much searching to find. It runs on the Arduino environment with minimal settings, but be careful because you may need to download specific drivers to recognize it! Unlike Arduino, it comes with a micro USB port, so you will need an adapter to connect it to a PC. Fully satisfied one year later.
