The HY-Tiny can also act as BMP

As last example in this “let’s make an ARM programmer” series, the HY-TinySTM103T: It’s a great little STM32 board with a nice set of features: 128 KB flash, 20 KB RAM, the usual mix of peripheral interfaces, and a little programming + debugging header at the bottom. We’re going to turn the one below (on the right) into a Black Magic Probe:… which can then be used to program and develop code on the one on the left!
