I recently tried to build the minimum possible quadcopter (for my skill set), and was surprised to find out betaflight worked with one of those cheap BlackPill boards. You just need to flash the STM32F411 board, and the config things through the CLI. Sorry if this is obvious to everyone here, but it did suprise me! I also tried to iterate my way up to a quadcopter from a motor and a battery - not sure how much I learned that way, but it was kind of fun.
This is the video, if anyone is interested I can post the pin outs and config settings I used. The final hardware was just that board, an IMU, some mosfets, and a little flysky receiver. It was more minimal that viable, but might be a good stepping off point for some.
