| Like our A-Star 32U4 programmable controllers, the Romi 32U4 Control Board is built around a USB-enabled Atmel ATmega32U4 AVR microcontroller, and it ships preloaded with an Arduino-compatible bootloader. The control board features two H-bridge motor drivers and is designed to connect to a {{pl|1452|Romi Encoder Pair Kit}} {{polpl|3542}} (available separately) to allow closed-loop motor control. It also includes a powerful 5 V switching step-down regulator that can supply up to 2 A continuously, along with a versatile power switching and distribution circuit. A 3-axis accelerometer and gyro enable a Romi 32U4 robot to make inertial measurements, estimate its orientation, and detect external forces. Three on-board pushbuttons offer a convenient interface for user input, while indicator LEDs, a buzzer, and a connector for an optional LCD allow the robot to provide feedback. | | Like our A-Star 32U4 programmable controllers, the Romi 32U4 Control Board is built around a USB-enabled Atmel ATmega32U4 AVR microcontroller, and it ships preloaded with an Arduino-compatible bootloader.

− | The Romi 32U4 Control Board can be used either as a standalone control solution or as a base for a more powerful Raspberry Pi controller. Its on-board connector and mounting holes allow a compatible Raspberry Pi (Model B+ or newer, including Pi 3 Model B and Model A+) to plug directly into the control board. Integrated level shifters make it easy to set up I²C communication and interface other signals between the two controllers, and the control board automatically supplies 5 V power to an attached Raspberry Pi. In this setup, the Raspberry Pi can handle the high-level robot control while relying on the Romi 32U4 Control Board for low-level tasks, like running motors, reading encoders, and interfacing with other analog or timing-sensitive devices. | + | The Romi 32U4 Control Board can be used either as a standalone control solution or as a base for a more powerful Raspberry Pi controller.

| The I/O lines of both the ATmega32U4 and the Raspberry Pi are broken out to 0.1″-spaced through-holes along the front and rear of the control board, and the board’s power rails are similarly accessible, enabling sensors and other peripherals to easily be connected. | | The I/O lines of both the ATmega32U4 and the Raspberry Pi are broken out to 0.1″-spaced through-holes along the front and rear of the control board, and the board’s power rails are similarly accessible, enabling sensors and other peripherals to easily be connected. |
