Thrust stand data logger utilising the dshot600 protocol and ESC telemetry.
Uses the dshot600 protocol to communicate with the a blheli32 ESC and receive telemetry. Telemetry data is used to calculate KV and all info is displayed on the OLED.
Great for testing hand wound motors KV or new/troublesome motors.
Optional loadcell can be added to the pin header highlighted with the orange circle below. Data is printed via serial every 2-3ms.
