32u4 Feather Development Board

This is a Feather form factor board based off the ATmega32u4.


It's compact, and much more feature filled than a standard Arduino Nano. It's also cheaper.


The 32u4 feather comes with a MicroSD slot for data logging.


For many applications, this is. a very useful feature, especially when working with sensors.


To comply with the feather layout, I added a PMIC onboard, for battery charging. This board supports Li-Ion and Li-poly charging and battery power usage.


I've calculated the price, with PCBWay's low cost PCB and PCBA, to be around 12 USD. That's almost as little as the Nano Every, with much more features.


The specs are:


8 Bit AVR ATmega32u4

32K Flash

2.5K SRAM

1K EEPROM

Onboard Data Logging

Onboard PMIC for power management and battery charging


We are a team of college students making lots of Feather boards and third party FeatherWings, so this is one of our creations.


Hopefully, with PCBWay's low costs we can easily prototype this.
