With the latest features, a layout which will make your build clean and easy, top-notch customer support, and an extremely competitive price, the Bardwell F4 AIO Flight Controller is perfect for your quad!

Version 1.3's JST connector's pinout is: 
VBat - Current - GND - NC - M1 - M2 - M3 - M4

Changes in version 1.3 include:

* 16 MB data flash chip for Blackbox logging instead of SD card reader.
* RX4 pad at corner for ESC telemetry
* TX6 pad added so there is one additional UART for general-purpose use
