Pre-soldered V4 ZMR 250 PDB with support for Naze32 Rev5 & MinimOSD

The ZMR 250 is a classic 250 racing drone frame. Its seems like it has been around from the start of the mini quad revolution and yet it's still the first choice frame for many getting into the hobby thanks to its study construction and great price point. As a frame, it's hard to fault, but it does lack support for electronics. That's where this ZMR PDB comes in. With it, it will transform any ZMR 250 frame from this to this (pics to come). The PDB makes the wiring up of your quad's electronics a total breeze and super fast. The PDB also helps to keep everything neat and tidy which saves a surprisingly amount of weight. The PDB is 100% compatible with all ZMR 250 frames and a lot of ZMR copy frames, so it can be integrated into a new build or retrofitted to an old frame.

This is the latest version of the ZMR PDB and it's a big step forward from the previous V2 PDB. With the V2 version you had to solder the 5 and 12 volt BECs to the PDB yourself, which was quite tricky. Now the V4 PDB comes with the BECs integrated and you can jumper the power outputs for the camera / VTX between 5 volts or 12 volts independently. The V4 version also comes an upgraded LC-power filter and support for the new SPRacingF3 flight controller.

As with the V2 board, the PDB still comes with integrated LEDs which look cool and are handy for orientation, and also a piezo buzzer which can be setup as a low voltage / lost model alarm.

The PDB is directly compatible with several flight controllers and an OSD, including the Naze32 Rev5, CC3D, SPRacingF3 and the MinimOSD. Your choice of FC / OSD is easily installed by using the provided header pin connectors. If you don't wish to solder these yourself, you can pay a little more for the pre-solder versions.

Features:

• 4 layer PDB, compatible with ZMR250/QAV250/custom build
• Support socket install of CC3D & Naze32 Rev5, SPRacingF3 flight controllers
• Support for MinimOSD via socket install - can be removed quickly
• ALL OSD features supported via breakout pins (rssi/current/batt2)
• Integrated SMD LED lights - red back, front white (with on/off switch)
• Easy VTX and camera install with jumper power output to suit 5 or 12 volts
• LC Filter to provide smooth DC voltage to FPV camera and video transmitter 
• Built in buzzer compatible with Naze32, SPF3 (for CC3D you will need PWM buzzer)
• New V4 PDB now comes with integrated 5V and 12V BEC modules - no UBEC required
• Easy ESC soldering connections - both top and bottom options.

Directly compatible with ZMR 250 - simply replace the base plate with the PDB

Integrated LED lights with on/off switch - useful for orientation
