Matek PDB-HEX: The “Im Building a Hexa” Power Solution
So, youve decided that four motors weren’t enough of a cable management nightmare. Youve graduated to a hexacopter, or perhaps a quad that consumes more power than a small UK village. Welcome to the PDB-HEX, where we stop pretending your 30A AIO can handle the heat. This is for the heavy lifters, the over-spec enthusiasts, and the people who actually read manuals.
Why You Actually Want It
Matek Systems knows youre going to push this thing until something glows. Thats why theyve rated this distribution board for a massive 140A of continuous current. Thats enough juice to make your neighbours’ Wi-Fi flicker. It handles up to 12S LiPo, because clearly, 6S was just a gateway drug to real power-induced anxiety. Its reliable, its chunky, and it wont give up the ghost when you decide to punch the throttle at 50% battery.
PDB
Input voltage range: 6~60V (2~12S LiPo)
PDB/current sense resistor: 140A cont, 264A burst.
ESC power pads: 60A cont. 100A burst
6x ESC power /signal/ telemetry pads
Current Senor: 264A, 3.3V ADC
Current Scale 125(INAV/BF), BATT_AMP_PERVLT 80 (ArduPilot)
Heavy Duty Copper: Thick 2oz copper traces because physics doesn’t care about your feelings.
Dual Voltage Rails: Separate 5V and 12V regulators so your flight controller doesn’t brown out when your gimbal kicks in.
Precision Sensing: Know exactly how fast youre draining your bank account… I mean, battery.
Notes
Please ensure your soldering iron is actually hot. Tacking a 10AWG wire onto a high-current pad with a 15W iron from the back of your shed is a recipe for a bad Saturday. Also, check your polarities;
