The full redesigned Omzlo PiJack V4 pHAT now lets you power your Raspberry Pi with any DC voltage source ranging from 6V to 32V, such as a car battery or a wall wart AC/DC adapter.
It features a DC/DC buck switching regulator that is designed to provide up to 3A to your board.
The Omzlo PiJack HAT features a barrel-type power jack for DC wall supplies, with a 5.5mm jack and a 2.1mm center pole diameter. You can also optionally solder:
- A 2 pin 3.5mm screw terminal block in order to connect power supply wires directly to the HAT.
- A 2 pin 2.54mm header in order to connect the 5V output to something else than the Raspberry Pi.
The board also features an "ideal diode" that protects the Raspberry Pi USB net in case the Raspberry Pi is accidentally connected both to the PiJack HAT and USB power.
By default, the board is provided without a 2x20 GPIO header. As an option, you can add an unsoldered 2X20 pin GPIO header with short leads, or you can go for an unsoldered stacking header 2x20 with extra long leads, instead.
Note: A Raspberry Pi board is not included with the PiJack HAT!
You can connect the PiJack to:
- Pi Zero/W/WH
- Raspberry Pi 4
- Raspberry Pi 3/3B+
- Raspberry Pi 2
- Raspberry Pi B+
Power your next Raspberry Pi with the PiJack HAT!
Omzlo found out that adding a DC power jack to a Raspberry Pi can be quite useful for many projects, allowing you to accept a much wider range of voltage inputs than the typical 5V provided through USB. So they decided to create this HAT!
This is version 4 of the PiJack, which uses an SMT jack connector.
