PBlowup If you want to use individual ESC's you will need a PDB for power to you ESC's, I believe the pads marked S1 to S4 would be where you connect the signal wires from the ESC's. If you need ESC telemetry you connect to the RX6 pad. If you want an easier build a 4 in 1 compatible ESC would be a better option. I purchased this board and found that the motors for S1 to S4 are not pinned out to solder pads you can only access these via the ESC plug, however motor S5 to S8 do have connections on solder pads you would need to re-map the motors via the CLI in betaflight to change the motors to S1 to S4.

PBlowup I flashed the firmware to the latest version in the 4.0 series and the LED is light permanently when powered on however no modes can be set.

PBlowup You need to translate you question to English as I don't speak or read in other languages.

PBlowup Thewire is a bit small for motors, these cables are used for connection to UART ports on flight controllers.

PBlowup I'm only using these with 4S batteries so I cannot confirm 6s batteries, however after a 4 minute flight they don't heat up at all.
