This programmable module is designed to be the core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its ATmega32U4 AVR microcontroller comes preloaded with an Arduino-compatible bootloader. On-board hardware includes dual motor drivers that can deliver 1.7 A per channel and an efficient voltage regulator that allows the controller to work with a 5.5 V to 36 V input voltage, along with level shifters that enable it to interface with a Raspberry Pi. This version (item #3118) does not include any through-hole components or connectors, allowing for customized assembly or standalone use.

Notes:

1
Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
2
Some I/O lines are used by on-board hardware.
3
Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
