This is an Arduino Nano compatible board with a breadboard. I purchased it 7-8 years ago, but I haven't had much opportunity to use it, so it has been stored at home. The pins have been soldered. I have confirmed that it powers on (photo 1). I have not checked any other functions. The only included accessory is the breadboard. The USB cable in photo 1 is not included. I am reusing packaging materials from my home. Thank you for looking.
