The LC filter should be bridged to the 9V side for most FPV gear. Step 3 - Configure LC Filter and FPV Gear Verify that the Dupont cables or servo extensions are available to connect P9 to the flight controller. All other headers are optional and pilots should refer to the pin headers documentation for more details. The P9 header is critical for flight and should be installed first. Turn the soldering iron temperature up, feed solder to help transfer heat from the tip to the pad, and be patient. Due to the massive copper area surrounding the pads to transfer large amounts of current to the ESCs, a large amount of heat is necessary to solder to this pad. Quick Start Guide Step 1 - Install Battery Wiresīattery wires up to 12 AWG are installed to the large through hole pads in the center of the board. Things will vibrate or rattle and eventually fail unless secured. I recommend sticking some to the part of the PDB immediately below any mounted components such as ESCs. KISS ESCs) to prevent wearing through the solder mask. Electrical TapeĮlectrical tape is a critical requirement to insulate parts mounted on the PCB (i.e. MassiveRC carries XT60 connectors and are perfect compliment for your PDB order. XT60 Battery Connector and PigtailĪn XT60 connector is the most popular battery connector and a pigtail easily connects to the center battery pads. Double row pin headers are very useful if the front/rear pin P1-P4 headers for LED connections. Single row pin headers aid in mounting KISS ESCs. Available on Amazon in 10cm length.Īn alternative to these are male to male servo extension headers such as these from Amazon.Ĭonsider picking up 90° 0.1" angled pin headers. It is recommended to use Dupont female to female cable connectors to wire the PDB to the receiver and flight controller. Recommended Additional Components Wire Extension Cables (3) 2x2 pin header for respective power supply outputs (5V, 9V, Filtered).(1) 1圆 pin header for the ESC and flight controller port.(1) 1x4 pin header for the auxiliary port.(1) CleanHawk 250 Power Distribution Board with all surface mount components installed.Shielded inductors to reduce switching power supply noise.Sufficient copper keep out area surrounding the mounting holes.2oz copper for efficiency and electroless nickel immersion gold plating for solderability.Centralized battery input pads to keep the high current paths through the board as short as possible.Optional bulk capacitance near the ESCs to help smooth out ripples.Battery voltage divider for dividing the voltage down to something manageable for the Frsky D4R-II.Multiple soldering points for accessories on the VBAT, 9V, and 5V rail.FPV LC filter that can select between 9V or 5V for feeding cameras and FPV transmittter,.Plan is to do red on the rear and white up front. User configurable color by changing resistors. 4 on bottom, 2 on top (not sure if top will be useful). 3A 5V for flight computer, OSD, and LEDs (i.e.Hoping that the new Emax BLHeli Oneshot ESCs fit. Designed for KISS 18A ESCs, ReadyToFly/Witespy's BearHug should fit just fine, and have pads for traditional ESCs.The printed circuit board replaces the bottom carbon fiber frame support on the Emax 250 / Nighthawk 250 quadcopters. The goal of the CleanHawk 250 PDB is to simplify wiring and imporve integration and reliability. This document outlines the basic tasks to get the CleanHawk 250 Power Distribution Board (PDB) up and flying.ĭocumentation can be found at the CleanHawk250 GitHub repository.
