A project log for A Risc-V HC-12 433Mhz Serial Bridge

Updating the original HC-12 with a CH32V003

After a 2.5 week postal journey, the first rev boards have arrived from OshPark

They’re still pretty small. Only slightly bigger than the original. I’ll sand the edges to remove the routing stubs and the swarf on the edge of the castellated holes. Then some manual paste application (I didn’t order a stencil for this revision. Maybe once the design is final and I panellize it, I’ll get a proper stencil done. ) 

All the parts arrived before the pcbs, so next project log will be once they’re assembled.

it working with https://reticulum.network/ or https://meshtastic.org/

  Are you sure? yes | no

The radio IC doesn’t support LoRa, so it won’t work with meshtastic. Reticulum RNodes also use LoRa, so that’s out too. Reticulum can use any physical layer modulation, so it’s possible to use these, with a second processor performing higher level protocol functions.
