openpilot revo mini results

Hi.
Just to let everyone know i just finished testing (on the bench) the
mini version of the openpilot revo.
I wrote a slightly different board config because i wanted to also test
the transparent serial link provided
by the orangerx 433 Mhz  LRS rc receiver (contains a rfm22 module)
running the openlrsng firmware,
so i moved the telemetry link to UART6 on the RC input port which
allowed me to have a single connector to the receiver-modem.
Everything worked fine at 9600bps (i didn't test the telemetry link at a
higher serial speed) until the openpilot revo mini died probably from
voltage regulator overheating.
I have mixed feelings for this autopilot board as i feel that the single
3.3v regulator is not up to the task
of a otherwise wonderfully small autopilot board.
If it is powered from more than 5v as mine was (6.6v) the regulator gets
very hot
Now on to make my own 1w rc-modem transceivers which will carry the rc
link as well as the telemetry.
BTW Felix i think there is a typo in the normal openpilot_revo_1.0.h
file because the PPM input pin used is the PA01 which ends up to servo 5
not 6 (counting from 1) of the revo board.
Below is the board file i used:
