KEYESTUDIO Pro Micro Atmega32U4 with USB Cable for Arduino Projects

WHY CHOOSE KEYESTUDIO!
1. EXCELLENT QUALITY
solder is very clean, everything is aligned nicely, all boards are well packed after function, voltage, current testing
2. COOL YELLOW BLACK DESIGN
The yellow trim is definitely a departure from the standard, dull, black boards, and the yellow silk screen on black mask really pops, making it easy to read the pin labels
3. REALLY SAFE
This board made from environmentally friendly components and materials, as well as environmentally friendly production technology
