A lid is good to keep your electronics safe. But it is also a pain since you have to turn on the board before you close the lid.
I invested in a small 433mhz remote which I connected to my anti spark circuit. I can now connect everything and close the lid and not activate the board before it’s in the water.
The 433mhz receiver runs on 3-24v, I used a very old power bank that makes 5V out of 1,5V.
The receiver has a relay that is normally open. I bought it on AliExpress.
