I had to purchase 5 of these boards so I have 4 extra (boards only) I will never use. I don’t claim to be a board designer, but the design works great and I have been using it for about 1 month with my DSC PowerSeries Alarm. If anyone would like one I am happy to send it to you for free (if you live in US). I can also provide a list of parts. The design uses a 30 Pin ESP32 ESP-WROOM-32 DEVKIT V1 board. Message me if you want one.
