Modifications

The control board includes a USB Micro-B connector that can be used to connect to a computer’s USB port via a {{pl|68|USB A to Micro-B cable}} {{polpl|2072}} (not included). The USB connection can be used to transmit and receive data from the computer and program the board over USB. The USB connection can also provide power for the microcontroller and most of the other hardware on the board (but not motor power); see Section 3.5 for more details.

The control board’s ATmega32U4 comes preloaded with the Arduino-compatible A-Star 32U4 USB bootloader, which allows it to be easily programmed using the Arduino IDE. For more information about programming the Romi 32U4 Control Board, see Section 5.

The board also has a 6-pin ISP header that allows it to be programmed with an external programmer, such as our USB AVR programmer. Pin 1 of the header is indicated with a small white dot and has an octagonal shape.
