- aappleby 4y agoI have a CH32V203 that I'll probably add support for, along with the 307 or whatever else I can get access to easily.
- unwind 4y agoVery cool, that's clearly a quite capable controller! The AUD$20 is for the full dev board, the bare chip seems to be around US$3 [1]. I've never hand-soldered anything in LQFP-100, sounds exciting!

- mrktf 4y agoThat cool CH32V307VCT6 chip have 1GBPS ethernet MAC interface, yes 1 gigabit. For me is very interesting what is real benchmark numbers. anybody have any numbers?
