im trying to battery power my pi for a DIY handheld console (i need to be able to do a safe shutdown due to read/write to sd card). Im aiming for a slim design and i need to be able to turn the pi on/off via a button wired to a GPIO pin (Apparently i can do this via GPIO 03?). Im avoiding a PiSugar 3 due to size and cost (and reviews). currently my design is a LiPO SHIM and a TP4056. im not sure if this will work and im hoping i could get some advice. https://preview.redd.it/fckjvy02pp3h1.png?width=1390&format=png&auto=webp&s=1db8b07c016c149ac37fde852e86cc5538ffcdf2 submitted by /u/OkCream8375 [link] [comments]
