Propeller Activity Board pre sale question
Hi,
Are the input pins 5V tolerant in the Propeller Activity Board ? If not ... will some resistor in series be enough ?
Thank you.

Pins P12-P17 on the servo headers have 3.9K resistors in line.

Note: if you use P12-17 on the left side of the breadboard, they DO NOT have the series resistor.
10) Analog to Digital Converter
Use the Analog to Digital Converter to monitor the voltage at analog inputs labeled A/D 0, 1, 2, and 3. It
will give a number from 0 to 4095, which tells what the voltage is in a range from 0 to 5 volts. The
converter used here is a 12-bit, 200 ksps SPI ADC, with a 5 V reference.
If not there's great documentation here - https://www.parallax.com/downloads/propeller-activity-board-guide
That was not my take on the question, but the ADC reference is a good one.
I guess we will not know until he/she responds.
Thank you all for your prompt reply.
