لوحة معالج TinyDuino (ASM2001-R) مستطيلة بدون حامل بطارية

I couldn't believe it when I saw how small this board actually is—it really is less than a quarter in diameter. The USB programming port works flawlessly, and I had my sketch uploaded in under a minute.

Packed up my whole Arduino project into something that fits in a shirt pocket, and the USB programming works exactly like the full-sized board. Finally a compact board that doesn't sacrifice the standard pin layout I need.

Honestly, I was shocked at how tiny this board is when it arrived, yet it runs my sketches just like a full-size Uno. The compact footprint without the battery holder makes it perfect for slipping into a small wearable project, and it’s surprisingly easy to stack with other modules.
