Yeap, it looks like UNO… but it’s not an Arduino! It is clone of an Arduino. Due to huge demand on Polish market we starter selling clones. However we made a lot effort to be them good quality.

First of all, they have ATmega328P in DIP form factor – You can replace broken one or use Arduino to burn bootloader (with other ArduinoISP or USBASP).

Second – it has ATmega16u2 as chip responsible for USB/Serial converter. Other clones have CH340/CP2102. They work OK, but it can not be programmed. That means they are more Duemilanove clones than UNO. With ATmega16u2 You can burn other firmware, and Your board will be recognized as keyboard, mouse or other device.

Third – we test each board. Make sure that connectors are straight and You can easily put some shield on. We program board with other sketch to make sure board works as expected.
