change MCU to STM32F042 since it provides read out protection, can recover 48 MHz clock from USB, and is easy to solder.

this is a large development board.
|
|
|
|
|
it accepts the classical STM32F103 (which I'm more familiar with), and CH32V203 (cheaper).
|
|
|
|
|
it has a proper debug port and buttons.
