Propeller Protection & Pull Down Considerations
Propeller Protection & Pull Down Considerations
01-06-2011, 08:17 AM CODE 5-113
When connecting prop to prop, a 2.2K ohm resistor is recommended to
protect the Propeller chip pin. In the circuit at the bottom of the
diagram posted above, what value is recommended and does the 4.7K ohm
pull-down resistor need a lower value? At first glance, it looks like
2.2K ohm could be used throughout. That would give 4.4K ohms to Vss with
each Propeller chip, close to the original recommended 4.7K ohms.
Considerations: how will this be affected with 20 props? With 50 props?
