STM8S103F3 P6 Development Board

Got this for a low-cost control project and was impressed by how the breakout board makes prototyping effortless. The STM8 chip is perfect for simple embedded tasks, and everything connected cleanly right out of the box.

Took me an afternoon to get the UART and GPIO talking, but the S103F3P6's built-in EEPROM made saving configs a breeze. For a board this cheap, the on-board debugging header is a godsend — no hunting for jumper wires.

For the price of a coffee, you get a proper breakout with the S103F3P6 already mounted, so I can wire it straight into my breadboard without hunting for a tiny adapter. The 3.3V regulator on board means I don't have to worry about frying it with a 5V supply from my USB-TTL. It's a solid little board
