Installing the V2 Beta configuration firmware, along with the utilisation of the tools.

F Series Installation

To ease the installation of F_Series firmware, APD has designed a purpose-built flasher for ESC firmware and bootloader files. This is used with all F Series devices however, units will still require a USB to UART adapter in some cases. A USB to UART adapter can be purchased from APD.

The pinout of the ESCs can be found here, it is important to note that the 200F3 does not require a USB to UART adapter.

Flashing instructions

  • Connect the ESC to the PC using the USB-UART adapter or Micro-USB cable. Ensure the two bootloader pins are connected together, this can be performed using a pair of tweezers or a small wire. Once connected, the LED on the ESC should be very dimly lit.

  • When running the APD Flashing Tool in Auto mode, the tool will automatically fetch the latest firmware to be installed on the ESC. An internet connection is required for this process.

  • Select the COM port for the ESC (the tool will automatically detect a new ESC plugged in).

  • Select the correct model for the ESC that is being flashed. Ensure the correct model is selected, as the wrong model will result in an ESC that will not boot.

  • Click Flash and wait for the process to complete. Once completed, the ESC can be directly connected to the config tool. Ensure the boot pins are no longer connected.

Once flashed, there are two methods in which an ESC can be connected to the V2 configuration tool. The USB to UART adapter can be used to directly connect to an ESC to edit its configuration settings. The ESC will signal that it is in configuration mode with a high-frequency LED blink.

Direct UART configuration is not supported on the 40F3. To configure these units, passthrough must be used. UART configuration will be introduced in a future update of the firmware.

In connection with a compatible flight controller stack (currently Betaflight units have been tested, others TBA), the ESCs can be modified using the FC passthrough method.

The 120F3 requires a component to be removed when using passthrough, see the image below.

In the case of any issues or if assistance is required, the team can be reached with the options found here. Units that are purchased from APD directly can have this beta firmware pre-loaded upon request.

HV Pro Installation

HV Pro installation instructions can be found here. DFUSE is required to update these units with the correct firmware. It is important to note that due to the logging changes, telemetry must be cleared to utilise the logging capabilities of the V2 tool.

Attempting to connect to the V2 tool while running V1 tool firmware will result in a pop-up prompt that can automatically launch the ESC into update mode for ease of installation
