The board brings reliable cellular connectivity to Raspberry Pi systems, empowering IoT projects to run seamlessly—even without Wi-Fi.
Wi-Fi dead zones are no longer a roadblock for connected devices. HashStudioz’s 4G LTE Cat IV HAT for Raspberry Pi enables continuous cellular connectivity for IoT, telemetry, and automation systems—offering developers a simple, power-efficient way to keep devices online anywhere.
Designed for Raspberry Pi 4 and Pi 5, the board integrates an LTE Cat 1 modem to provide reliable 4G network access, striking a smart balance between performance, cost, and energy use. It’s ideal for applications such as smart farming, environmental sensing, logistics tracking, and industrial control—scenarios where consistent connectivity matters more than bandwidth speed.
The key features include:
- 4G LTE Cat 1 connectivity for IoT and M2M systems
- Plug-and-play compatibility with Raspberry Pi 4 and 5
- Interfaces: UART and USB
- Supports Nano SIM cards
- Low-power design for continuous field operation
- AT command access for advanced configuration
Compact and plug-and-play, the HAT connects directly to the Raspberry Pi’s GPIO header, instantly transforming it into a cellular-enabled IoT gateway. It supports Nano SIM cards and features both UART and USB interfaces for flexible data exchange. Developers can also issue AT commands directly to the modem for custom setups and deeper control of network functions.
The LTE Cat 1 link ensures stable uplink and downlink performance with lower power consumption compared to faster LTE categories like Cat 4. That energy efficiency is key for remote, battery-operated IoT nodes that must stay active for months or years.
Beyond convenience, the cellular capability extends IoT access to rural or infrastructure-limited areas where Wi-Fi and Ethernet aren’t feasible. Combined with Raspberry Pi’s strong processing power and open-source community, it allows engineers to scale projects from prototype to deployment quickly and affordably.
As cellular IoT gains momentum across industries, this 4G LTE expansion board strengthens Raspberry Pi’s role as a practical platform for edge intelligence—bridging the gap between concept and connected reality.
