PYRODRONE F4 RACE with VTX PIT mode - 30x30mmIt's finally here! The pyrodrone F4 board has been one of the very few boards with perfectly flat one side which lot of guys been utilizing as a "shelf" for their VTX and RX.

It's finally here!
The pyrodrone F4 board has been one of the very few boards with perfectly flat one side which lot of guys been utilizing as a "shelf" for their VTX and RX.
It was time to reroute the pads and offer a direct clean solder option for the TBS UNIFY V3 VTX and the TBS Nano RX similar to the Whitenoise Synergy FC.
The Pyro F4 RACE also has a built in socket which makes it plug & play with the Pyro32 F3 45A 4in1 ESC (The correct harness is ONLY included in the ESC package)
Please check below for tips and Betaflight Settings.
- MPU6000 Gyro STM32F405 CPU @ 168mhz, can be overclocked
- 2-6S direct battery input
- 3.3V 100ma, 5V 2A BEC
- 5V and Vbat Camera Power
- Built in configurable Betaflight OSD
- Flat bottom PCB for SUPER CLEAN builds
- 36x36 PCB with 30.5x30.5 mounting holes
- 6 UARTS.
- UART1 (INVERTER FOR SBUS),
- UART2 (FREE),
- UART3 (INVERTED TELEMETRY), use CLI command : Set tlm_halfduplex=off UART4 (Free),
- UART5 (Smart Audio)
- UART6 (Free)
- The Pyrodrone F4 RACE flight controller can power HV VBAT or 5V Video transmitters.
- BF Target: PYRODRONEF4
Please make sure to jump the correct selection for your VTX.
If you want to use the VTX PIT mode function please type the following in the CLI command line:
resource pinio 1 A15 (Hit Enter)
Set pinio_box = 39 (Hit Enter)
resource pinio 1 A15 (Hit Enter)
Set pinio_box = 39 (Hit Enter)
Save (Hit Enter)
Assign a switch to the VTX PIT option in Betaflight MODES tab.
If VTX PIT mode is NOT needed then just solder your VTX and fly! (no additional settings needed)
If you want to solder the TBS UNIFY 5V direct to the board which is where this FC REALLY shines then here are couple tips for you.
Using the TBS Direct mount feature means you have to flip the board upside down with the USB to the left side of the drone.
SO REMEMBER to change the board orientation in Betaflight configuration tab.

SO REMEMBER to change the board orientation in Betaflight configuration tab.
Both the VTX and the board have "anchor" Pads on both sides of the VTX, but we do not recommend using all these anchor points for easier future maintanence in case you ever have to remove the VTX.
Here is what we recommend.
Use a very thin piece of the double sided tape that is provided in your TBS UNIFY V3 package and apply it on the VTX as shown in the below picture.
This will work as a place holder for you to line up and solder the 4 points.
When sticking the VTX to the board make sure the 4 points on the VTX (VID-AUD-GND-5V) line up with the 4 pads on the flight controller.
Once lined up solder the 4 points.
Once lined up solder the 4 points.
Now it's time to solder your receiver.
The board is labled for TBS NANO RX as the holes perfectly line up with the Nano RX, but you can really use any RX and just choose the correct type of receiver in the Betaflight configuration page.
Our preferred way of mounting the RX is with silicone wires rather than direct solder, Again for easier future maintenence purposes.
Please check the below picture:
For correct voltage reading change the Voltage scale value to 160
If you charge your batteries over 4.20 per cell AKA HV then remember to adjust the Maximum Cell Voltage to 4.4 otherwise the average cell voltage will read wrong on your OSD.

Great Multi-Function Watch
Color: Gray/Digital/Gray
I absolutely love my Timex Ironman watches. I have had many over a very long period of time.
Wonderful set of functions for the price.
Very affordable.
Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often.
Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time.
Great to be able to set three independent alarms.
Potential to capture a huge number of splits with the stopwatch.
I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

Just fine if you have simple needs...
Color: Black/Digital/Black/Green
Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up
