Nano DIP: the smallest complete Arduino board 33 x 10mm
Here, I share technical solutions that arised during the development of my solar-bike.
1 x fast 350ksps 8-bit real DAC The USB supply pin is protected by an ideal diode that doesn't have a 0.7V voltage drop A 2-pole header, which is connected to D2, can be used as a jumper. To make this job easy, I could have opted for small 0201 SMD parts and thin 2 mil traces. The pin numbers are different than the Arduino Nano or UNO, you must change them in the sketch.
