OP-COM clones can become "bricked" if you attempt an online update or use incompatible firmware. Common symptoms include:
: For stable communication, use FTDI drivers v2.8.30.0 (referenced in the archive name v20830 ) or v2.8.14.0. OP-COM_RESTORE_FTDI_to_ORI_v20830.7z
Select the appropriate binary ( .bin or .hex ) file for your intended firmware version (e.g., v1.39, v1.45, or v1.59). Enable VCC and program the flash memory. OP-COM clones can become "bricked" if you attempt
If the device is still non-responsive, the main microcontroller (MCU) likely needs new firmware. Enable VCC and program the flash memory
Connect the device to your PC via the ICSP port if using a programmer.
The restoration process generally involves two parts: repairing the FTDI communication chip and reflashing the PIC18F458 microcontroller. 1. Restore the FTDI Chip
: Attempting to move from version 1.64 to 1.65 (or similar) results in a non-responsive device. Restoration Steps
