[RISC-V MCU CH32V103 Review] - 0: Three unexpected things when meeting for the first time [Copy link]

 

This is the actual object of this review:

The first thing I didn’t expect was that it was so small and exquisite, which was completely in line with the temperament of a “reduced” instruction set.

The second and third unexpected thing are the programming interface and a power interface:

The flat USB interface on the left means that the user needs two male USB cables of the same type, which seems to be relatively rare in actual applications. The programming cable on the right uses the early 10-wire connection method similar to AVR-ISP. I don’t know how many people have this cable. If not, you need 10 double-female jumper cables. The reason why I was able to equip these two cables so quickly is because I had the interest and conditions to collect various interface cables for a long time. I don’t know if other users will be a little confused here.

I am going to make a board myself. If you are interested in playing with it, I will give you a copy of the bare board. I only applied for 5 chips. I can't give you the soldered one.

One end of the emulator is directly plugged into the computer or HUB, and the other end of the Dupont line is connected to the board. Conventional design should not be a problem

The smaller problem was unexpected.
