## 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](https://www.st.com/en/microcontrollers-microprocessors/stm32f103vc.html)

-  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](https://github.com/RoboticsBrno/sboot_stm32) based on [sboot_stm32](https://github.com/dmitrystu/sboot_stm32).

### [ESP32-DevKitC](https://www.espressif.com/en/products/devkits/esp32-devkitc)
