C-Board firmware downloads are now available on GitHub.

C-Board is the external DSP board I built for UV-K5 (and compatible radios) to extend digital features such as FT8 receive, APRS receive/decode, GPS-assisted functions, and related experiments.

Hardware introduction (previous post): C-BOARD (DSP-Board) for UV-K5

Repository

github.com/phdlee/cboard-uvk5

Release package: v0.32

What is in v0.32

cboard_v032.uf2 — C-Board firmware (RP2040)
cec0.3P.packed.bin — companion UV-K5 / UV-5R Plus firmware
cboard_v0.32.zip — packaged set + original notes

Download v0.32

Why this is public now

Earlier builds were shared only with beta testers. After that, many people asked for the firmware by email. I was not checking that mailbox regularly, so I could not send copies to everyone who asked.

Publishing the last beta package on GitHub Releases should make it easier to download without waiting for a private reply.

Source code status

Source code is not uploaded yet. I am still organizing the tree before publishing it. For now, please use the Release binaries.
