A USB bootloader for STM32F103 microcontroller boards, derived from the Leaflabs maple-bootloader, designed for use with the Arduino_STM32 core and Arduino IDE. It supports Maple boards and generic STM32F103 boards with multiple build targets for different LED and button pin configurations.

Use cases

  • upload Arduino sketches to STM32F103 boards over USB without a serial adapter
  • flash firmware to generic STM32F103 blue pill boards
  • use DFU protocol to program STM32 microcontrollers
  • enable USB re-enumeration on boards without Maple reset hardware
  • bootload Maple mini and Maple clone boards

When to choose

  • you are using the Arduino_STM32 core with the Arduino IDE on STM32F103 hardware
  • you want USB firmware uploads on a Maple or generic STM32F103 board without a USB-serial converter
  • you need a lightweight, hobby-grade bootloader for STM32F103

When to avoid

  • you are using the official STM32duino core (STM32Duino core by STMicroelectronics) which uses its own bootloader approach
  • you need a certified, standards-compliant USB implementation for commercial or safety-critical products
  • your board is not STM32F103 or lacks a ~1.5k pull-up on PA12
