If you have a black PCB with v1.1 on it

Note that the microcontroller must be programmed with the v1.1 firmware.
Any NPN transistor that is pin-compatible with the 3904 should be OK.
Use 940nm IR LEDs.
If you have a green PCB with v1.0 on it

Note that the microcontroller must be programmed with the firmware.
Any NPN transistor that is pin-compatible with the 3904 should be OK.
Use 940nm IR LEDs.
