+ | ====== Miniature Relay Shield for Wemos D1 mini - Design A ====== | ||
+ | |||
+ | Inspired by [[https:// | ||
+ | |||
+ | It mounts a max of 8x miniature relays (G6K-2F-Y) so it is easy to add a remote control option to different types of push button control panels (that are otherwise not really designed with wireless remote control in mind), like: | ||
+ | * any (regular type) push-button panel (as seen in the video about the AC unit). | ||
+ | * any matrix arranged in a 4x4 or 5x3 or 6x2 button matrix. | ||
+ | |||
+ | Once wires are soldered to the correct places, on the control-panel, | ||
+ | |||
+ | It is possible to cut the PCB in different ways, in order to fit the PCB into tight spaces. This might however also limit the max number of relays available, on the remaining PCB. | ||
+ | ---- | ||
+ | A PCB specifically designed to fit the tight space of a MaxxFan, is available here: | ||
