Dependable. Works for years now.

I tested the CH551 and the CH552. Both are great little boards.
I think the CH552/554 board could do without the 3V3 regulator, since the chips have a builtin 3v3 LDO.

Great little boards for learning the CH55x chips (and 8052 programming in general). You can do a lot with the 10kB (actually 12kB in my testing) of flash available on the CH551. Electrodragon has documented these boards well.
