I have put together some more of these PCBs for anyone that wants to run the TIU in passive mode. You can checkout this thread that found the benefits of using a 20A 22uh choke HERE. This includes a power LED and TVS diode. Also included will be the PCB standoffs in the pictures below for easy mounting
$26 a per PCB or 4 for $95 with free USPS shipping to the Lower 48
