TinyHawk 2 Freestyle Resources

Resources for the Tinyhawk 2 Freestyle. This page contains annotated images for the flight controller board and dimension data for mount spacing. 

Top side of the flight controller board with the original VTX still attached.

Top side of the flight controller board with the original VTX removed.

Bottom side of the flight controller board.

Top and bottom of the board annotated showing positions for connecting replacement VTX and crossfire protocol receivers. 

Board dimensions. This image gives the exact spacing of the mounting holes for this flight controller. Useful if you want to make your own adapter plate.

Pin-out diagram. The Tinyhawk 2 Freestyle uses the STM32F – 411CEU6 chip. This diagram shows the physical pins which are used for Betaflight resource assignment.

For softserial options the best assignment is the LED strip pinout which has a physical pad on the board. 
If you need to use the original smart audio UART for something else then simply breakout the LED strip pad as softserial and swap smart audio over onto that. This will free up an extra UART to be used for example GPS connection.
