Description

The goal of the CleanHawk 250 PDB is to simplify wiring and improve integration and reliability. The printed circuit board replaces the bottom carbon fiber frame support on the Emax 250 / Nighthawk 250 quadcopters and drones.

Features

• 3-4S compatible
• Designed for KISS 18A ESCs, ReadyToFly/Witespy's BearHug should fit just fine, and have pads for traditional ESCs. Hoping that the new Emax BLHeli Oneshot ESCs fit.
• 3A @ 5V for flight computer, OSD, and LEDs (i.e. WS2812), telemetry/BT, etc. (85%+ efficient).
• 3A @ 9V for FPV camera, vtx, and LEDs. (92%+ efficient),
• (6) RGB LEDs. 4 on bottom, 2 on top (not sure if top will be useful). Testing waters here. User configurable color by changing resistors. Plan is to do red on the rear and white up front.
• FPV LC filter that can select between 9V or 5V for feeding cameras and FPV transmitter,
• Multiple soldering points for accessories on the VBAT, 9V, and 5V rail. Helps to contain the wiring mess.
• Battery voltage divider for dividing the voltage down to something manageable for the Frsky D4R-II.
• Optional bulk capacitance near the ESCs to help smooth out ripples.
• Centralized battery input pads to keep the high current paths through the board as short as possible
• 2oz copper for efficiency and electroless nickel immersion gold plating for solderability.
• Sufficient copper keep out area surrounding the mounting holes
• Shielded inductors to reduce switching power supply noise.

What's Included

• (1) CleanHawk 250 Power Distribution Board with all surface mount components installed.
• (1) 1x4 pin header for the auxiliary port
• (1) 1x6 pin header for the ESC and flight controller port
• (3) 2x2 pin header for respective power supply outputs (5V, 9V, Filtered)

International Shipping

Note: USPS First Class International shipping doesn't offer tracking information after it leaves the United States. As a result, I can't guarantee delivery or help resolve lost mail. If this is a concern for you, please contact me to investigate alternative shipping options with tracking.

To date no packages have been lost, but some have been severely delayed due to things like the postal service in the destination country being on strike.
