3 WARNING! 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. Some parts on board may get hot. Don't touch any electronic components when in operation. Never connect conductive elements from top to bottom of board as this may cause of short circuit. 3

4 1. 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. Also on naze32 CB [conversion board] are OSD with compatibility of minim and kv team software and openlrs (openlrsng software). Future list fits ZMR250, QAV250 and RCX250 frames fits with most popular FC on market 1.6mm thickness with 70um copper current metter (90A) high lumen's LED's on front and back pins for minimosd direct connection with user selectable serial port number (UART1 or UART2) pins for UART1 or UART2 (GPS, external telemetry etc) pads for all ESC's and main battery low-pass PI filter (800mA maximum current) for FPV elements PWM to analog converter (RC) for radio link RSSI 5V/1.5A voltage regulator pads for radio link, video supply (filtered) on board buzzer 4

5 2. 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. If you use minimosd is recommended to solder it on beginning. PDB is prepared to use minimosd without soldered pins. If you have minim like this on photo you must remove all pins. Components must be on top. If not minimosd tie VIN and VOUT pins on minim video in/out connectors. Install battery leads with proper gauge for the amount of current you plan on running. Check two times polarity of battery connectors and pads on PDB. When soldering ESC's wires to PDB also pay attention with polarity. Install frame spacer (for top plate). Remember to use nylon screws (attached in package with cytrynka PDB). Now you can connect PDB with arms and main bottom plate (our PDB replace top bottom plate). 5

6 WARNING: Never cut pins directly on FC. This may destroy your gyro. 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. 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. WARNING: Remember to change the orientation in baseflight or cleanflight by entering the following: set align_board_yaw = 90 save Don't forget to check that all the movements are right in the GUI! If you made a mistake and the movements are not right, your quad will crash!! 6

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. WARNING: Remember to change the board orientation in baseflight or cleanflight in yaw axis! 7

8 CC3D CC3D best working with cytrynka PDB when it flashed with latest cleanflight firmware but it can work with Openpilot software with some limitations (no voltage, current and RSSI reading). Picture I: Cable colors for CC3D 8

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. Motors wiring with OP and Cleanflight firmware CL and OP have different motor mixing nonetheless in both firmwares user can define motors mixing but on CB we added jumpers for define which firmware you using. CC3D Buzzer usage with Openpilot and Cleanflight Information about using buzzer with CC3D with OP firmware can be found here: Before you must solder jumper Buzzer off on CB. With Cleanflight info about buzzer can be found here: Don't solder (or desolder) jumper Buzzer off on CB. 9

10 3. 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). EXTERNAL 5V UBEC SOLDER PAD 5V SOURCE Radio link input pads and RSSI signal converter On board are solder pads (RSSI, PPM, 5V, RxD, GND) for RC direct connection. Our PDB for direct connection accepts only PPM sum signal and if your receiver does not operate with PPM you must use PWM to PPM converter or connect receiver to FC (or you can use Spektrum Satellite connecting it direct to CB connector). RxD pad is dedicated for FRSKY telemetry. RSSI signal have PWM to analog RC like this: RSSI from converter goes to CB and to solder pad and this can be used to connect it directly to minimosd (bypassing FC). 10

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: soldering wire to pad on PDB and directly to OSD. In this case is not possible to log current value using FC (default connection PDB->CB). In this case user must activate feature in cleanflight configurator: on image above in Scale the output... is 400 but must be 815! or via CLI using commands: feature CURRENT_METER current_meter_type = 1 current_meter_scale = 815 current_meter_offset = 0 12

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. MinimOSD can be directly programed with UART2/1 (depending on selected serial port) connectors on PDB using FTDI programmer. OSD DTR is connected to RESET line on minim. If is used other OSD like minim (or with not compatible pinout) short selected pins on PDB. Solder jumpers for serial ports selecting for minim. For UART2 solder like this: For UART1 solder like this: 13

14 WARNING: Minim used for the cytrynka PDB must have a 5V modification. See below or check the link: For some minims 5V mod needs only shorting this pads: 14

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. This is simple diodes (not WS2812B or similar). To switch off lights just remove LED OFF jumper. 15

18 5. 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! SJ2, SJ3 jumper for Current Sensor and RSSI signals. Must be close! 5V SOURCE - with this jumper you can select 5V source (internal UBEC or external with input on pad on M1 connector) jumpers on NAZE32 conversion board SJ5 selection for UART port number for Spektrum satellite receiver (UART1 or UART2) SJ1 for S.BUS inverter activation jumpers on FLIP32(+) conversion board SJ2 always open SJ1 for S.BUS inverter activation SJ3 FRSKY input on softserial jumpers on CC3D conversion board solder jumpers group on bottom this jumpers are for motor mixing selection dependig firmware on CC3D (OP- openpilot, CF- cleanflight) Buzzer - closing circuit for buzzer output on SERVO channel (with transistor key). 18
