PiXtend V2 -L- Hardware Manual
Connection Notes
The power supply of PiXtend V2 -L- is realized via a regulated and short-circuit-proof
power supply with an output voltage between 12 and 24 V DC. The power supply must
comply with the legal requirements of the country in which the system is used. When
purchasing a power supply, please check the corresponding test marks.

.
The internal voltage regulator of PiXtend has an energy reserve. This ensures an
uninterrupted power supply for voltage drops at the supply input of 10 milliseconds. The
energy reserve is designed to ensure the said bridging time throughout the life of the
device.
The supply port is duplicated on PiXtend V2 -L- (2x VCC, 2x GND).
Only one pair must be connected (1x VCC, 1x GND). The second pair can be used for
"looping through" the supply voltage to other devices or for supplying the digital outputs
"VCC DOx-x".
