Title: Homing Missile Build Doc?
Post by: Vtguy22 on August 13, 2019, 11:25:39 AM
Hello,

  Does anyone happen to have a build doc for the homing missile?

Thanks,
Paul.

Unless somebody has a better suggestion, I would follow what is written on the board. The "pwr" components have been 100n MLCC 2.5mm capacitors on other VFE boards that I've built. I assume it is the same here.

Thanks, the power board is my bigger problem.  I'm not sure what diode it takes, and if it's a split rail.

Given the circuit is a mix of the Rocket and Focus, I would GUESS it uses the "charge pump" (aka split rail) setup on the switching board. The board has power rails to both the "V+" and "V-" connections, also suggesting this.

Can't find definite info either way. Peter's schematics are... sparse in details, so the files aren't that much use here unfortunately.

In the download bundle, I think he put an asterisk next to the ones that require the charge pump

Edit: just veried that the Homing Missile does have the asterisk in the doc so it is required
