EB500 Bluetooth Modules (Set of 2)
I found one set of these classic Bluetooth Adapters originally designed for the BASIC Stamp 2 and having an AppMod header to connect to any development board with the appropriate socket. Not tested, but should be working. See description below for complete details.
EFX-TEK RC-4 SSR Board
I found a few of these RC-4 boards which were originally planned for both a Christmas Light control and a DJ lighting control project. Already populated with Crydom Solid-State Relays. New old stock. See description below for complete product details.
