Yahboom Multifunctional Programming Development Board for Raspberry Pi Jetson Nano Orin Building ROS1 ROS2 Robot Expansion Board with 9-axis IMU Sensor STM32F103C8T6 Core (ROS Expansion Board)

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.

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.
