2.2.1 Power circuitry
The power circuit consists of the power socket, diode bridge, selection jumper JP41 and
two low dropout linear voltage regulators. Power options include USB and LPC-Link 2 but
for the best performance external power source is recommended.
Note:
PN7462B v2.1: external power supply 7.5V max.
PN7462B v2.2: external power supply 13.5V max.
