Read this manual very carefully before you start installation of our PDB. Incorrect use may result in fully damage of product, personal property and cause of serious injury. Operating with current over 60A may damage PDB! This is high degree complexity hobby product and operating it requires some basic mechanical and electrical abilities.

Page 4: Overview And Future List
Overview cytrynka PDB is a power distribution board designed for ZMR, QAV or RCX 250 size frames. It was created because I terribly hate clutter in cables. It's provides to use direct connections for most of popular FC on market (naze32, CC3D, flip32 etc) because it using conversion boards. -
Page 5: Installation
Prepare cytrynka PDB comes completely soldered and you don't need to solder nothing out of wires for battery, ESC, FPV (OSD including). Also, if you have not ordered CB for CC3D with wires you need to solder it. Installation We recommending to use spacers between bottom plate and our PDB to get best ventilation. - Page 6 Don't ask why just don't do it Flight controller installation naze32 Using naze32 flight controller with our cytrynka PDB is the best and easiest choice. User must only solder pins on naze and Conversion Board, connect it together with PDB, setup in configuration and fly.
- Page 7 FLIP32(+) FLIP32(+) flight controller is very similar to NAZE32 and installation is almost the same. Just remember to solder pins on bottom side. Angled pins for PWM outputs must be a little bit prepared before soldering. Longer side of pins must be shortened about 2mm.

- Page 9 WARNING: All of CC3D's on market are with soldered PINS. Before using it with cytrynka PDB you must desolder it. It's not simple. Best solution is to remove first plastics from pins and after that removing pins one by one.

Page 10: Hardware On Board
Linear 5V UBEC cytrynka PDB has an on board 5V linear regulator with maximum current output 1.5A. It necessary for powering FC, minimOSD or other OSD board, some FPV cameras and transmitters, GPS and programmable LED's. Also on board are pads for connection UBEC on one of ESC's and by solder jumper user can chose 5V source (internal or external not both). - Page 11 RC receiver solder pads...
- Page 12 Current meter cytrynka PDB has default on board current sensor with amperage up to 90A. WARNING: Current meter can work with amperage up to 90A but PDB is designed to carry current only up to 60A. There are two ways to get current value: •...
- Page 13 minimOSD connector With our PDB is possible to install minimOSD directly on board. For this purpose under the FC are pads to solder pins. WARNING: Before soldering minim on PDB select desired serial port number through solder jumpers. We recommending use UART2. See below.
- Page 14 WARNING: Minim used for the cytrynka PDB must have a 5V modification. See below or check the link: https://hoogvlieger.wordpress.com/2013/11/01/rctimer-minimosd-5v- mod/ For some minims 5V mod needs only shorting this pads:...
- Page 15 Video and LC filtered 12V For those who wants fly FPV on board are a LC filtered 12V power supply for camera and video transmitter and video IN/OUT solder pads. LED diodes On front and back of PDB are LED diodes- green on front, red on back. All of this are connected to 12V line.

jumpers jumpers on PDB (main board) • “LED OFF” - jumper for switching off/on led's on front and back (parallel with goldpin 2x1), • SJ6 – solder jumper on bottom side. This is for closing LC filter circuit when step-down regulator is not installed. With step-down must be open! •... - Page 19 Some photos of our last installation...
