What is the ALPON X4?

ALPON X4 is Sixfab's industrial edge IoT computer for telemetry, gateway, and protocol-aggregation workloads. It runs on a Raspberry Pi CM4 (Broadcom BCM2711 quad-core Cortex-A72 at 1.5 GHz) with up to 8 GB LPDDR4 RAM and up to 32 GB eMMC flash storage. Connectivity includes ETH/G (1 Gbps, data plus optional PoE+), ETH (100 Mbps, data-only), Wi-Fi 5, LTE Cat 4 with eSIM, Bluetooth 5.0 / BLE, and GNSS. It includes a TPM 2.0 and is managed through ALPON Cloud. The fanless aluminum enclosure has a documented -20 °C to +60 °C operating range and IP40 protection, with no liquid-ingress protection. Built on Raspberry Pi.

Key features

Raspberry Pi CM4 host

Broadcom BCM2711 quad-core Cortex-A72 at 1.5 GHz with up to 8 GB LPDDR4 SDRAM and up to 32 GB eMMC flash storage. Native Raspberry Pi ecosystem, Debian-based ALPON X4 OS, and standard ARM64 containers.

Multi-network connectivity

Dual Ethernet (ETH/G: 1 Gbps, data plus optional PoE+; ETH: 100 Mbps, data-only), LTE Cat 4 with eSIM (eUICC SGP.22), dual-band Wi-Fi 5, Bluetooth 5.0 / BLE, and GNSS / cellular geolocation. Reachability depends on configuration, service availability, and coverage.

TPM 2.0 hardware

Discrete Infineon SLB 9670 TPM 2.0 provides hardware-backed security capabilities. Its presence alone does not confirm secure boot, measured boot, or an application key-management policy is configured. Validate the security configuration for your deployment.

Industrial form factor

Fanless aluminum enclosure, 111.16 × 99.9 × 33 mm at ~457 g, IP40. Operating range -20 °C to +60 °C, up to 95 % RH non-condensing, MTBF over 13 years at 25 °C. DIN rail and wall-mount kits available.

Flexible I/O and power

2× USB 2.0, 1× HDMI, an RJ45-style Add-on connector with 6 GPIO signals plus 5 V output up to 1 A and GND, 2 user buttons, and an RGB LED controlled through an I²C expander. The Add-on connector is not Ethernet. Use one power input: 9–30 V DC rated (full peripherals at 12–30 V), USB-C PD 15 V, 1.8 A (27 W), or optional PoE+ up to 25 W. PoE cannot cover the 27 W simultaneous system peak; reduce peripheral load or use DC/PD.

How data flows on ALPON X4

Telemetry pipeline

Step 1

Connect

Connect sensors, meters, and field devices over Ethernet, USB, or supported GPIO interfaces. Confirm pin assignments before wiring.

Step 2

Process on CM4

Cortex-A72 handles parsing, normalization, and protocol translation (Modbus, OPC-UA, MQTT, REST) inside containers.

Step 3

Aggregate & filter

Local rules thin, batch, or threshold the data so only what matters leaves the device.

Step 4

Forward

Your application forwards events to its configured backend over Ethernet, Wi-Fi, or LTE.

Why this matters

Logic runs on the edge. Your application determines which field data is processed locally and what is sent to a backend. Configure and verify network access, data handling, and security for the site's requirements.

Where ALPON X4 fits

IoT gateways & telemetry

Aggregate field sensors and meters, normalize the data, and ship events to ALPON Cloud or your backend over LTE, Wi-Fi, or Ethernet.

Industrial monitoring & SCADA

Modbus and OPC-UA aggregation, PLC supervision, machine condition monitoring, and edge data brokering for factory and energy sites.

Smart city & infrastructure

Street furniture, lighting controllers, environmental sensing, traffic counters, EV-charger backhaul, and digital signage — managed remotely as one fleet.

Remote sites & cellular failover

Unmanned cabinets, well sites, pumping stations, agricultural sensors, and pop-up locations where LTE is primary and Ethernet/Wi-Fi back it up.

Platform & ecosystem
