Remarks |
- Note: The user button is also connected the the BOOT0 pin. This means that this button should be pressed when flashing the microcontroller.
- Trivia: This board is a clone of the official Maple Mini originally made by Leaflabs. The originial Maple Mini was designed to be used with the standard Arduino IDE. The official Maple products are no longer supported. The software has since been forked and is maintained under the STM32duino flag, supporting more boards than the original Maple project.
