The Adafruit ItsyBitsy is a small, powerful, and Arduino-compatible microcontroller board. The ItsyBitsy is only 35mm long and 17mm wide. It has 6 Power pins, 6 Analog/Digital pins, and 17 Digital pins. It has about the same power as an Arduino Uno or a Feather 32U4.It is therefore ideal if you have made a prototype on a large Arduino and want to make the final project smaller.
The ItsyBitsy 32U4 3V 8MHz uses the ATMEGA32U4 chip. This is the same chip as the Arduino Leonardo. There are also two special 3V pins on the board. There is a vhigh pin code, this pin code is a power pin whose voltage is higher than VBAT and VUBB. There is also the digital #5 pin. This pin connects to a level shifter.
