RBCX

Hardware

Board is based on STM32F103VC microcontroller and ESP32-DevKitC.

STM32 is used for motor control and other low-level tasks. ESP32 is used for high-level tasks like communication with mobile app and sending commands to STM32 via UART.

STM32F103VC

  • ● 72 MHz, 32bit ARM Cortex-M3
  • ● 48 KiB RAM, 256 KiB Flash
  • ● 5x UART, USB
  • ● Debug support (with ST-Link)
  • ● Programmable in C++, with FreeRTOS and stm32cube framework, in Platform.io
  • ● Our bootloader based on sboot_stm32.
