Husarion CORE2 STM32 Board for Robotics Projects Works with ESP32, Raspberry Pi 3, or ASUS Tinkerboard

Husarion CORE2 is a board designed to make robotics projects simpler and faster to complete with pre-configured software and online management. Projects can start using LEGOs, before moving to 3D printed or laser-cut version of the mechanical parts without having to spend too much time on the electronics and software part of the project. Two versions of the board are available: CORE2 combining STM32 MCU with ESP32 WiFI & Bluetooth module, and CORE2-ROS with STM32 instead coupled to a Raspberry Pi 3 or ASUS Tinkerboard running ROS (Robot Operating System). Both solutions share most of the same specifications: MCU -STMicro STM32F4 ARM CORTEX-M4 MCU @ 168 MHz with 192 kB RAM, 1 MB Flash External Storage – 1x micro SD slot USB – 1x USB 2.0 host port with 1A charging capability; 1x micro USB port for debugging and programming via FTDI chip Expansion Headers hRPi expansion header for CORE2-ROS […]
