PN532 - Pre-Jumpers, Resistor between sel0 sel1?

by paulchabot on Fri Apr 30, 2021 12:53 pm

I have an early PN532, the one on the manuals title page. However, the manual doesn't seem to reference it. I remember something about having a resistor between sel0 and sel1 to select SPI, but cannot be sure.

If anyone knows, that would be very helpful.
