Digital Input Voltage Thresholds

Post by NovaBiele »

Was just curious what the threshold values are for HIGH/LOW on the BCS inputs?

I'm planning on interfacing directly with a 3.3v microcontroller and am curious if 3.3v will properly trigger a HIGH or if I need some sort of level conversion.

I couldn't find this info anywhere online. Thanks in advance

Can't say that I've ever seen the required level published anywhere. I'd say try it with 3.3 and see if it is reliable. If not, wire up a darlington fed from the BCS 5V supply.
