# FC V5b Quickstart Guide

This is a quick guide that can be used to quickstart and test the core functions of the V5b Flight Controller Board!

The V5b FC board uses the standard PROVES Kit software development toolchain. At this time it is cross compatible with V5a firmware but has some key incompatabilities with V5a software.

If you want to use V5a software on a V5b board note that the enable levels of *all* the load switches are inverted. This means that although V5b boards enable their load switches by setting their `value` to `True` V5a boards enable thier load switches by setting their `value` to `False`. This can cause some surprises if not carefully checked.

> NOTE: V5b Flight Controller Boards are still affected by the bug with the deep sleep implementation for RP2350's in CircuitPython. If your board appears to "disappear" soon after booting simply power cycle and attempt to establish a serial connection ASAP to get around this issue.

## Individual Functional Checkouts
22-
At the moment the best way to verify individual hardware functionalities is to enter the `REPL` by interupting any running code and allowing `reply.py` to setup manual test functions. You can interupt the `main` loop with a `ctrl+c` terminal command. Note this appears to work significantly better with a dedicated serial terminal software like `Tabby` or `Warp` rather than the built in serial terminals in `VS Code` or `Cursor`.

Ideally all of the functions in all of these objects should execute without errors when the FC board is fully connected with all other boards in the PROVES Kit. You can learn more about what functions are availible in each object by either inspecting them directly or using the following pattern in the `REPL`:
