module's pins plus Vdd, Vin and Vss. Vdd is +5 volts and Vin is 6 – 9
volts (depending on your power supply). NOTE: the Vdd pin on the 20-
pin socket comes from the Vdd of the Stamp module (pin 21) while the 5
Vdd sockets above the breadboard come from the Board of Education's
5-volt regulator. Use the 5 Vdd sockets for anything requiring more
current than what the Stamp can provide. Also, the pins in the "red"
row of the servo connectors are connected to Vin. Also note: the barrel
jack is designed for a center positive, 2.1 mm (pin) x 5.5 mm (barrel)
plug.
