J11 SPI interface and in-system-programming
When the shorting block on JP1 IS IN THE SS
position, J11 is used for the SPI port. When the
shorting block on JP1 is in the RST position, J11
is used for in-system-programming. 1 PCINT2/SS/OC1B PB2

5 GND
6 VCC
J12 Power supply
When JP2 is shorted, J12 supplies power to both
the MiniServo’s processor and the servos. When
JP2 is left open, J12 only supplies power to the
processor.
1 GND
2 VCC
J13 Screw terminal Power supply
When JP2 is shorted, J13 can supply power to
both the processor and the servos. When JP2 is
left open, J13 becomes the dedicated servo
power supply. 1 SVCC
