Power Distrubition on ST800

Some items need for this build arrived and it was time to start working ...

The folding arms mount very close to the centre of the fuse plate which does not leave a lot of room for electrical cables to run. With the ESC ordered I also ordered a power distribution board for $0.99 from MyRCMart, think I got it on a special , so I was determined to see if this can fit and I can make use of it ... btw , MyRCMart got some bad write up on the net ...for me they where okay with fairly fast shipping.

As it turns out ...so far ...so good ... will see as build progress ...
Multicopter Power Distribution Board



Multicopter Power Distribution Board test fit between ST800's folding arms , close fit but doable ...




Note , the side where the permanent arms mount I made a cut out for the arm to fit flush with fuse board.



I drilled two holes between the moving arms to fit the board more solid to fuse.

Cleaned up the board where I cut the space out for the permanent arm , Use your Dremel , lovely tool isn’t it ! ?







 Power Distribution Board Soldered up and mounted , note the permanent arm got enough space at the top.



I use two 3mm plastic screws for the mounting.



Also put Insulation tape on the bottom of the Power Distribution Board , just in case it touches the Fuse plate .

Left cable is for the UBEC and then main battery feed cables  ...


AttoPilot -180A














Next up ! Mounting and soldering in the Attopilot 180A current sensor ... "Description: This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider."  Got this from SparkFun , fast shipping !




Hope all of this are going to work ... need a battery for my multimeter ...
