## Description

desertcart.com: Yahboom Robot Expansion Board V3.0 with STM32F103RCT6 Support RaspberryPi 5/Jetson/RDK Series 9-Axis IMU Sensor ROS2 (Ver 3.0) : Electronics

Review: Really nice ROS controller! - I really like this controller board. It has 4 DC motor outs, so it works great for 4wd / mecanum robots. It also has pwm and serial bus servo outs, RGB LED out (for ws2812), SBUS in (for an RC receiver), and plenty of power connectors. It is controlled by USB and there are images available from Yahboom for ROS1 and ROS 2 for Raspberry and Jetson platforms. (I’m using raspberry pi). But you could plug it into a PC running linux and run ROS there and it would work. I have two of these boards now and I will probably buy more. It’s a great general purpose robot controller. One note -at the time of this review, the Yahboom ROS2 image is using ROS2-foxy. If you are on a newer ROS distribution you will have a more work to get everything running.
Review: Unable to use, difficult to power - I bought this board as a test bed, to further my robotics education. I had attempted to use this board to run a self-balancing robot, to no avail. Also, when I hooked a raspberry pi 5 to the board, the board would not power the pi.

## Features

- Compatible with multiple development boards: Compatible with Raspberry Pi Jetson series development boards, Sunflower Pi, industrial control board development boards, and also has multiple power supply interface outputs, providing stable power supply for DIY expansion boards.★★★Note: 3.0 compatible with raspberry Pi5/Jetson/RDK Series，Support Raspberry Pi 5 power supply protocol.
- Rich peripheral interfaces: The expansion board supports 4-way encoder motors, which can drive various vehicle types, such as mecanum wheels, four-wheel differentials, tracks, etc.; it also supports PWM servos and serial bus servos, which can adapt to various forms of robot arm development; it also supports USB serial communication, CAN bus communication, and SBUS bus communication.
- Multi-functional robot expansion board: The control board is equipped with a 9-axis IMU attitude sensor, which can obtain real-time posture information of the robot and is widely used in ROS robot kit development.
- Fully open source data: Provides basic peripheral driver routines written in STM32CUBEIDE, including driving encoder motors, PWM servos, serial bus servos, reading and solving 9-axis attitude sensor data, and controlling multiple communication interfaces; open hardware schematic, which is more user-friendly when used with the driver routines.
- Support 12V voltage input and multiple power supply interface output, refuse to use a safe and stable power supply system. Support ROS1 and ROS2

### ⭐ Unable to use, difficult to power
*by D***N on November 10, 2025*

I bought this board as a test bed, to further my robotics education. I had attempted to use this board to run a self-balancing robot, to no avail. Also, when I hooked a raspberry pi 5 to the board, the board would not power the pi.

### ⭐⭐⭐⭐⭐ Beyond my expectations!
*by X***O on September 28, 2023*

Great board to learn robotics. It also comes with free courses, firmware, python codes, and ROS/ROS2 codes to build a robot! The technical support is also patient and knowledgeable to provide solutions to my problems.
