Be carreful, i don't use this capacitor for "replace" the battery voltage during the disconnection/connection!

"The very easiest solution (that working for me) simply consist to solder an external maxi capacitor (0,1F - 5,5V)between the positiv and negative pinout or cable of the power supply (board side, not battery side).

Then, why not adding wind/current sensor in next version for optimising and reduce the USV drift.
"Grant, just my vision for the RTL mode on sea:
When the boat go in RTL mode (by failsafe or by remote action), there are two possibility for the boat:

What do you think also of a possibility to RTL by the same previous way?
On sea you can have many obstacles (buoy, boat, jetty and so) preventing a direct RTL to home position.
Regarding the rally point, RTL to the nearest, seem the best and…"
I have the same issue with a Droppix board (the french Pixwhak like's).
Normaly, my Droppix is powered by the "power module" and by the ESC via the receiver/pwm to ppm conveter. In this configuration, it's working…"
One think very important in boat configuration, you need to start the system on shore or if is it impossible, you need to disable the gyro autocalibration at startup.
Because in water, the boat alway moving and the gyro is not able to make a…"
I receive my RFD868+ bundle.
But when i'm connecting the modem with RFDtools 1.5, i can't see and change the 868Mhz frequency, i have only the choice between the 902/928Mhz band.
Is there an hardware frequency band error with…"
