ADRSPWDJ Raspberry Pi DC Power Input Expansion Board
The Raspberry Pi DC Power Input Expansion Board allows you to use DC jack power adapters with your Raspberry Pi, which are more stable and have a wider range of options than USB power supplies.
By using the long pin header, it is also possible to stack other HATs on top.
In addition, the design does not block the camera connector or heat sink, ensuring that it does not get in the way of experiments or installation.
It conforms to HAT size so that it can be attached by simply removing the top cover of the official Raspberry Pi case.
Product application examples
・Power supply to always-on IoT devices using Raspberry Pi
- Perfect for experiments that require a stable power supply
- When you want to use a standard DC jack power adapter
Product Features
Can be used with a standard DC jack type AC adapter
There are limited sources of USB connector type power supply adapters.
However, if you use an AC adapter with a DC jack, there are many alternatives available, making it easy to obtain.
By using a DC jack, a physically stronger connection is achieved compared to a USB connector!
It provides a more stable power supply and a stronger connection, ensuring the stability of your Raspberry Pi.
・Complies with the official Raspberry Pi 4 case size*! HAT size, slim design convenient for experiments and integration

The board is designed to be as slim as possible to avoid interference with other devices and cables during experiments and integration.
Long pin headers allow you to stack other expansion boards.
This expansion board only uses 5V and GND GPIO pins, allowing for highly flexible expansion.
Please be careful!
To use this product, you will need general knowledge about electronics and electronic circuits.
