Relay Boards
Description
Four different boards to hold 4 relays (Link below) or 4 relays and an Arduino MKR series board (with headers or without) and another one to hold 4 relays and a MKR board with holes for zip ties to clean up wiring. The oval hole in the Arduino versions is for battery cable pass through. Two boards to screw to the bottom to hold a 3.7v Lithium battery. https://www.amazon.com/dp/B07BTTRCTT?psc=1&ref=ppx_yo2_dt_b_product_details Here are the relays used. https://www.amazon.com/dp/B07XGZSYJV?psc=1&ref=ppx_yo2_dt_b_product_details M2x10 and M2x20 screws used to attach the PCB to the board. You could probably use #4 x .25" self threading screws as well. Enjoy, and post a print if you like! Print it in whatever you like, at whatever resolution you like, and there are no supports needed.
