D.1.8
D.2
D.2.1
This connector allows for control of the LCD in “4-bit
Upper Nibble Mode”
D.2.2
Provides for the connection of a transponder reader
coil.
The inductance of the coil has to match the capacitance
value of C2 + C3 + C4 for resonance at 125 kHz.
Other frequencies can be obtained by changing the
PWM output frequency of the PIC16F877, but will
require also the optimization of the input filter.
