The Romi 32U4 Control Board 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 ATmega32U4 AVR microcontroller from Microchip (formerly Atmel), 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 Romi Encoder Pair Kit (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 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 ships with all of its surface-mount components populated, and it includes a number of through-hole parts and mounting hardware, as shown in the picture above. Note that assembly (including soldering) is required; please see the user’s guide for assembly instructions.
The Romi chassis itself and other parts required to build a complete Romi 32U4 robot are not included; these are listed below, along with some optional additions.
What you will need:
To build a robot with the Romi 32U4 Control Board, you will need a few additional parts:
- a Romi Chassis Kit (this includes motors, wheels, one ball caster, and battery contacts)
- a Romi Encoder Pair Kit
- six AA batteries; The Romi chassis and control board work with both alkaline and NiMH batteries, though we recommend rechargeable NiMH cells
- a USB A to Micro-B cable to connect the robot to your computer for programming and debugging
- tools to help with kit assembly; see the user’s guide for a list of specific tools
