The Irdroid USB Infrared transceiver does not have a bootloader and firmware update is only possible via a ICSP serial programmer. The firmware can be updated using MPLAB and a PIC programmer. In order to program the module you will have to remove the plastic cover. To attach to the module you wil also need a 5×1 male pin header. Attach the pin header to the PIC programmer , then connect to the USB Infrared transceiver board as shown on the pictures below. You need to provide power to the module with the PIC programmer. That option has to be ticked in the PIC programmer settings in MPLAB. The import the target HEX file and program the module. After a successful programming the Irdroid USB blue led should be lit.
