Versions
The first version has one external module.
Using the official protoboards.
Custom PCB with a hole for the camera, but because the flash and the pin orientation, this idea was not good.
It has a large prototyping section with the ESP32 pins exposed. Behind the NRF24 and ESP32 boards there is pins for sensors connected to the Flipper Zero pins.
Compact form factor.
Combination of small tweaks in general, prepared to be customized.
Different versions for other makers.
Added support for 4 pin sensors and small layout improvement. Enhanced ground planes under the ESP32 antenna and NRF24/CC1101 modules.
Small revision on pcb holes, silkscreen.
This version has two external modules, the upper and lower pins connect to a different module. It is a similar footprint, but does not fully replace Version 1 because it has no place for sensors.
No more module swap, removed the prototyping area to add a secondary external module header.
Small revision on pcb holes, silkscreen and component positions.
