ALLNET SATA NAS HAT Top Board Expansion Module for Raspberry Pi

The ALLNET SATA NAS HAT Top Board is a high-performance expansion module designed to add SATA III storage capabilities to your Raspberry Pi. This HAT (Hardware Attached on Top) board enables you to connect a 2.5-inch SATA HDD or SSD directly to your Raspberry Pi, transforming it into a powerful NAS (Network Attached Storage) device. With USB 3.0 connectivity and UASP support, it delivers fast data transfer speeds up to 6 Gbps. The board features a JMicron JMS578 USB-to-SATA bridge chip, ensuring reliable and efficient data communication. It includes a 40-pin GPIO passthrough header, allowing you to stack additional HATs or connect other peripherals. The board also supports a 40x40mm cooling fan (not included) to keep your drive cool during extended operation. Power is supplied via a 5V DC barrel jack, with the board providing power to the connected SATA drive. LED indicators for power and drive activity provide clear status at a glance. The ALLNET SATA NAS HAT is compatible with Raspberry Pi models 4B, 3B+, 3B, 2B, and B+, and works seamlessly with Raspberry Pi OS and other Linux distributions. The package includes mounting hardware and a USB 3.0 cable for easy setup. Whether you are building a home NAS, a media server, or a backup solution, this expansion board offers a compact and efficient way to add reliable storage to your Raspberry Pi.
