I would love to see a power module with headers to help us get a jump start on building custom power modules. I’m thinking of trying to build my own power module with LiPo backup but also options for a heavier battery (maybe 12v) along with terminals so that the one power board could be used to power and backup power hungry servos as well as the board & modules.
Also, if you ever release the LiPo board, it would be great for it to have an interrupt to signal power loss & restoration.
