Is 35mm too wide? I’m sure it is. Here’s one that’s only 24mm. As small as I can make a pair of 5050’s and a beeper. needs a special beeper, too!

Now with data out. Only 35mm wide, for really tight builds. The beeper is this:

Although I suspect any 9.6mm diameter active buzzer would work. Notably, that rules out most eBay options which are 12x9.6 or thereabouts.

Better sizing! Fewer Pads! Less chance starting a damn fire if you know what I mean

Note: No clearance on standoffs is an almost guaranteed short circuit with metal standoffs. And the minim cutout is undersized. And why not have a 12v reg, since there’s space. Anyway, don’t use.
I like an OSD, but I hate wiring it. Put the Pololu reg on top or beneath the board. Fundamentally just a respin of the Atom PCB, but with bigger tracks for the power leads because the Atom PCB doesn’t look like it’d stand up to a constant 5A per motor load.
The pads are mostly laid out to be as directly wired for a SN20a as possible, but the pads for motor #1 are reversed to provide better current handling for the negative rail.
There are ground and signal “pads” near the power pads for jumping from the ESC to a second wire for running up to the FC.
Warning: Untested. Order at your own risk.
