Backpack-style addon boards for the Flipper Zero!

This is a collection of addon boards for the Flipper Zero multi-tool in the style of a backpack that clips behind the Flipper!

Right now it features only an ESP32 wifi board, like the official wifi devboard, only formatted as a backpack and with an SD card slot fitted. There is also a protoboard to create your own designs in the same formfactor.

The backpack framework is designed to fit snugly to a Flipper inside its silicone case. Without a silicone sleeve, the board will have 2mm of space around the Flipper, which might be undesireable.
