This is a dedicated programmer for changing the program for the BL-RPX4. Firmware for updating the older model programmer (BL-R26P3) is also available. Even after updating the firmware on the program card, it is still possible to change the program for the older RPX3 and RPXS ESCs.
To update your old firmware to the latest version, please see the following page: https://teamyokomo.com/topics/16074/
