This is an alternative hardware platform for FujiNet that allows you to build your own using all through-hole technology (THT) components and an Espressif ESP32-DevKitC-VE devkit board. You could probably also use a ESP32-DevKitC-VIE board, but you will need to use an external IPEX connected antenna since it lacks the on-board PCB antenna. You must use ESP32-WROVER based devkit boards, the cheaper ESP32-WROOM boards lack the PSRAM needed by FujiNet code these days.

The PCB is designed for flexibility in building, with different cabling options and headers for the buttons and LED's if you want to mount this in your own enclosure. Most components are "jelly bean" parts you may already have or can be purchased for one or two cents in quantity from the usual China based suppliers. Total cost of the build should be around $20, depending on where you source your parts. Please see the assembly page for more details.

Currently this board is not supported by the FujiNet updater app so you will need to use Platform IO to build and upload your own binaries. Build with the 8MB flash target since the devkit boards have half the flash of the 16MB WROVER modules used on the SIO mounted FujiNet designed by mozzwald. In normal operation is should not really matter since 6MB in the 16MB version is currently reserved for over the air (OTA) updates and the release build uses a little more than 2MB of flash as of March 2021 so lots of free space still for future development.
