What You Can Build With This
- Create a portable file server by connecting a USB flash drive to your Raspberry Pi Zero.

- Expand storage with an external hard drive or SSD on a low-power Pi.
Compatibility
This adapter works with any device that supports USB OTG, including the Raspberry Pi Zero, Zero W, Zero 2 W, and Model A+. It operates at standard USB voltages (5V) and requires no additional drivers for most Linux distributions. For full-size Raspberry Pi models (3B, 4B) that have standard USB-A ports, this adapter is not needed but can be used with a micro USB power input port for data if supported.
Wiring Notes
Simply plug the micro USB end into your Pi’s data port (not the power-only port if separate) and connect your USB device to the female end. For Pi Zero, the micro USB port nearest the Mini HDMI is typically the data port; check your board labeling. No external power is required for low-power devices, but for high-power peripherals, use a powered USB hub.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi 4?
The Raspberry Pi 4 has full-size USB-A ports for data, but this adapter can be used with its USB-C power port only if you’re using an OTG cable that supports data; this micro USB adapter is not designed for USB-C. It is compatible with micro USB OTG ports found on Pi Zero and A+ models.
Can I charge my phone with this adapter?
This adapter is designed for data transfer, not charging. Using it to connect a charger may not provide sufficient power and could damage the adapter if used with high-current chargers.
What if the device is not recognized?
Ensure that OTG support is enabled in your operating system. On Raspberry Pi OS, it is usually enabled by default. Check dmesg for USB enumeration errors, and if the device draws too much power, use a powered hub.
