So I got Fio V3 with XBee Pro 900 XSC-S3B along with USB explorer.
I have cut the trace off from USB Explorer, removed resistor connected to RSSI LED on Fio V3, and they both work well as expected.
Now, as far as Fio V3 with XBee, I won’t worry too much about re-wiring RSSI LED since it will go inside a container.
But I’d like to know if it is possible to re-wire(or by-pass) RSSI LED on USB Explorer.
Does anyone know which pin they use for RSSI output on the Pro 900 XSC S3B?
Datasheet in the product page shows Pro 900HP and I’m pretty sure that pin #6 isn’t RSSI pin for 900 XSC S3B…
