Interesting that they put a full blown XX32F103 there for jtag and still use a CH340 for serial. They could easily use the F103 for both, to bring the cost down

Interesting that they put a full blown XX32F103 there for jtag and still use a CH340 for serial. They could easily use the F103 for both, to bring the cost down (save on USB conn, 12mhz crystal, serial IC, etc). That's savings of 0.30 USD right there.
- sitkack 8y agoThey probably reused jtag and serial from different projects, which makes sense for a V1. If it is popular, I am sure they would implement the changes you list.
