This document introduces the hardware configuration of the OpenCR board. It is a project that shares robotics technology through open source ROS between communities, academia and companies. The OpenCR board is designed as an embedded board for ROS 2.0. It uses an STM32F746 microcontroller and sensors like an accelerometer and gyroscope. The document provides details on the board's specifications, including its communication interfaces, LEDs, buttons, battery charging and block diagram. It also mentions that OpenCR can be used for the TurtleBot3 robot.
