Summary of 7-42VDC to USB Supply/Charger
This article describes a compact, high-performance DC-DC converter designed to power 5V USB devices like Raspberry Pi and Arduino from non-standard 7-42V sources such as batteries or solar panels. The unit features a tiny form factor (56x21.5mm) suitable for mobile applications and production environments where 12V or 24V is standard. It supports up to 2A constant draw and is built with high-quality components for stability and longevity.
Parts used in the 7-42VDC to USB Supply/Charger:
- High performance parts
- 56x21.5mm PCB board
- Mounting holes
- 7-42VDC input section
- USB output interface
Introduction
Having to use a Raspberry Pi and other USB Devices in an electronics production environment where 5V isn’t standard, I have noticed a lack of power supplies capable of fitting in. A unit had to be designed to fit into systems where 12V & 24V are the norm or where batteries / solar panels etc are the only supply method available.
Development
Using only high performance parts, a solution was prototyped to meet this criteria. Only a few tweaks are needed to improve spacings, add mounting holes and to make the board completely production ready. The unit has a tiny form factor, only 56×21.5mm, meaning it is small enough to travel around with you.
Battery powered robots, adapting an old 9 or 12V wall charger, powering your Arduino / Raspberry pi in-car project, a simple and easy solution is here.
Compatibility
The power supply has been designed to power/charge the following devices:
– Raspberry Pi
– Arduino Boards
– iDevices
– Mobile Phones
– Other 5V USB Devices up to 2A constant draw
Construction
The power supply is constructed using high quality parts, to ensure long life and great stability in your application:
