7214-X3 Voltage Regulator
These units have high efficiency switch
mode providing better heat dissipation than linear voltage regulators.
Shielded PCB design and output EMF coil makes a stable, low noise voltage
output. Reverse polarity is built in. Has 2 to 5
cell LiPo, 7.2 to 21 volt input. Output is 3.3 volts, 3.5 amp
