Espruino and STMicroelectronics

The Espruino firmware runs on a variety of STMicroelectronics STM32 devices. We sell the following development boards based on STMicroelectronics STM32 ARMs:

	STM32F103	Espruino Original
	STM32F401	Espruino Pico
	STM32F411	Espruino WiFi

However pre-built firmware is available for many other ST-based boards, or you can build firmware yourself:

• STM32L496 Discovery, supported by ST
• Hardware Reference for common Espruino hardware
• List of boards with Espruino firmwares
• Espruino GitHub repo with build instructions
