Ligne 10 : − The Romi 32U4 Control Board <small>([https://www.pololu.com/category/149/a-star-programmable-controllers Lien Pololu])</small> is designed to be assembled with a Romi chassis to create a capable integrated robot platform that can easily be programmed and customized.+ − 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.+

La carte contrôleur Romi 32U4 <small>([https://www.pololu.com/category/149/a-star-programmable-controllers Lien Pololu])</small> est conçue pour être montée sur le châssis Romi pour créer une plateforme robotique qui peut facilement être programmée et personnalisée.
Comme pour le contrôleur programmable A-Star 32U4 de Pololu, la carte de contrôle Romi 32U4 est réalisé autour d'un AVR Atmel ATmega32U4 disposant déjà de fonctionnalités USB 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.
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 {{cl|30|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.
