Many pcb projects are in progress to run KaraDio.
Dimitris works on a pcb with esp8266, the external ram and the vs1053 with the complete set of option by juumper (a0 and type of ram).
I hope he can sell it soon (with mounted components).
discover1977 has made a pcb not yet finished, but with the full hardware including the lcd and more.
See his project at https://github.com/discover1977/Wi-Fi-WEB-radio
Christophe has made a minimalist pcb to be used with KaraDio, but can be used in many other projects. The lc soft vs1053 can be plugged directly on the pbc.
