At this moment, there are three versions of the CX-20 on the market with different firmware upgrade techniques. The difference between Open-source flight controller, Zero Tech flight controller and A Big Shark Flight Controller is:
- CX-20 with open-source flight controller can be upgraded by the user;
- Zero and A Big Shark versions only can be upgraded with the software made by the manufacturer;
- In the CX-20 with the Zero Tech Flight Controller the firmware can be upgraded only with special USB cable from the manufacturer.
The Cheerson CX-20 multi-rotor board is using the PL2303 USB-to-Serial Bridge for firmware upgrade purposes. That means, first you have to install the driver (also included in the downloaded file) for PL2303 on your computer before you can proceed with the firmware upgrade process.
