More info


Adafruit Feather 328P is a module with a built-in ATmega 328P AVR microcontroller clocked at 8 MHz. The built-in system works with 3.3 V logic, has a flash memory with a capacity of 32 kB and 2 kB of RAM. The board is compatible with the Arduino IDE environment, and the USB connector allows its programming and debugging. In addition, the built-in Li-Pol battery connector allows you to power the board and charge the cell via USB. Battery voltage can be measured through the analog input of the microcontroller, thanks to which the device gains mobility and can signal the need to connect to USB for charging.
