System ground: (same as pin 23)
General-purpose I/O pins: each can source and sink 40 mA. However, the total of all pins should not
exceed 300 mA (source or sink).
5-volt DC input/output: if an unregulated voltage is applied to the VIN pin, then this pin will output 5
volts. If no voltage is applied to the VIN pin, then a regulated voltage between 4.5V and 5.5V should
be applied to this pin.
Reset input/output: goes low when power supply is less than approximately 4.2 volts, causing the Spin
Stamp to reset. Can be driven low to force a reset. This pin is internally pulled high and may be left
disconnected if not needed. Do not drive high.
System ground: (same as pin 4) connects to power supply’s ground (GND) terminal.
Unregulated power in: accepts 5.5 - 12 VDC (7.5 recommended), which is then internally regulated to
5 volts. Must be left unconnected if 5 volts is applied to the VDD (+5V) pin.
