Hi all! In the quad that I use to work i've a Mikrokopter "tower" (all board), I created an "hot swap" adapter that allows me to move all the board/receiver from a quad to another in just a minute.
In the photos I had not yet entered the base for the receiver (now is between the GPS and the NC), but now even that is connected to PPM Sum with Flight Control, all in a single "tower".
For safety reasons all the contacts are redundant on more pins, this is the list of contacts used for any "signal or power":
8 / - LiPo
8 / + LiPo
6 / C I2C
6 / D I2C
4 / + Buzzer
4 / - Buzzer
2 / pwm signal for each servo
2 / -5V for each servo
2 / +5V for each servo
2 / + Led Strip front
2 / + Led Strip rear
4 / + 5V Aux
4 / - 5V Aux
10 / Telemetry Port
This system is of course usable for any type of flight card, even for ArduCopter APM1/APM2, just obviously adapt the cards and the strips.
Certainly this adapter is used on heavy quad, since the bulk and weight (46g) would be ridiculous to install it on little quad.
In the photos are missing the four 10 mm spacer that fasten the two boards of the adapter with 4 plastic screws.
Obviously after each swap is necessary to load the appropriate tab setting flight and motors matrix table, simple and quick.
Tower ready to go, full Mikrokopter electornics with "3DR Radio" telemetry and rx s-bus, "all in one" installed in the "hot swap adapter".
Yeah, the new 3DR Radio work fine also with Mikrokopter boards! :-)
In the "male" base adapter there's the two pnp transistor and two resistor for the "led strip".
