Description
The Sixfab Base HAT bridges the gap between your hardware and robust cellular networks. Acting as an industrial mini PCIe interface, it empowers you to deploy global 3G, LTE CAT-M1, CAT 1, CAT 4 and even next-gen 5G RedCap connectivity to the edge.
While designed to mount seamlessly to any standard form-factor Raspberry Pi (A+, B+, Zero, 2, 3, 4, and 5), it is fully compatible with any Linux device featuring a similar 40-pin header. Deploying on a different system? You can also connect the Base HAT to any Linux device or PC directly via USB.
GPIO functionality is unavailable in USB-only mode.
Build your custom cellular setup
The Base HAT is a versatile carrier board that serves as the foundation of your project. Because every deployment is unique, this board gives you the freedom to separately add the exact Mini PCIe modem (CAT-M1, CAT-1, CAT-4, or 5G RedCap) and antennas that fit your specific requirements.

Real-world applications
- Edge AI & video surveillance (5G RedCap)Securely pipeline heavy processed datasets, computer vision inference results, and industrial robotics data using the low-latency, power-optimized footprint of next-gen 5G RedCap.
- Mobile gateways & failover internet (CAT 4)Harness high-bandwidth CAT 4 connections to power commercial vehicle WiFi, stream digital signage, or provide backup internet for remote enterprise branches.
- Fleet tracking & smart kiosks (CAT 1)Utilize the cost-effective, medium-bandwidth capabilities of CAT 1 for real-time GNSS vehicle logistics, smart vending machines, and remote point-of-sale terminals requiring continuous uptime.
- Remote off-grid sensors (CAT M1)Leverage the ultra-low power consumption and extended signal penetration of CAT M1 to reliably transmit soil moisture, weather, and basic telemetry from remote agricultural sites and smart meters.
