Pro Mini 3.3V / 8MHz Arduino 互換マイクロコントローラ

I use this microcontroller for all my simple projects. Great value for the price, very powerful.

Great for quickly prototyping an idea.

I use this in everyone one of my creations. Nothing is more powerful or user-friendly than this product. Highly recommended!

Product working great. I wanted to put on a protoboard using the I2C, however those holes are offset. I can understand why, and not a show stopper, but slightly inconvenient. Just had to solder wires directly to the board. No biggie.

Good work. I load scatch without any problems, and it works normally. Just use special USB TTL adapter for 3.3v arduino with DTS.
