This board is sold by several vendors on AliExpress, Amazon and ebay. It does not have name, but since it comes in the same form-factor and color as the Bluepill line of boards, I think it makes sense to use that name. Flashing is a bit cumbersome as I always had to press the reset button in time when OpenOCD tries to connect to the CPU. There is no dedicated reset pin exposed on the board.
