BLHeli firmware for ZTW Spider 40A OPTO Small ESC
ZTW Spider 40A OPTO Small ESC with stock SimonK firmware can be easily flashed with BLHeli using Cleanflight interface. I just did it, the whole process took few minutes. To be true, it took me more time to find out which firmware should those ESC be flashed with, than to flash them. For unknown reason this information is well hidden in the internet! So, here is short guide:
- We will be using Cleanflight BLHeli passthrough interface. It is build in in laster Cleanflight / Betaflight / INAV firmwares
- Use latest BLHeliSuite. I used 16.3.14.7.0.0
- Connect ESC to flight controller
- Connect flight controller to USB port
- Run BLHeliSuite software
- From Interface menu select
ATMEL BLHeli / SK Bootloader (Cleanflight)
- Select COM port and click
Connect
- Connect ESC to battery
- Click
Check
to detect connected ESCs - BLHeliSuite will detect unknown firmware with SimonK bootloader
- Select ESC (1, 2, 3 or 4) and click
Flash BLHeli

firmware and flash - BLHeli 14.x enables Damped Light by default. That might not be a best idea for big (> 8") propellers so you might want to disable it
