Seeed Studio reComputer R1125-10 Raspberry Pi IoT Gateway & Controller

Description

Seeed Studio reComputer R1125-10 is a fanless industrial Raspberry Pi IoT gateway and controller built on the Raspberry Pi Compute Module 4 platform. It is designed for industrial edge computing, building automation, remote monitoring, and field gateway deployments where reliable serial communication, isolated I/O, dual Ethernet, wireless expansion, and long-term stability matter more than raw desktop-style performance.

The R1125-10 is especially attractive when you need one compact controller that can bridge RS485, RS232, DI, DO, Ethernet, HDMI, LTE, LoRa, Wi-Fi, BLE, TPM 2.0, NVMe SSD, and optional PoE or UPS. That makes it a strong fit for Modbus RTU / Modbus TCP gateways, BACnet building systems, industrial telemetry, smart city cabinets, HVAC monitoring, energy management, and remote device integration.

Because it belongs to the reComputer R1000 / R1100 family, this system is not just a generic Raspberry Pi box. It is built for DIN-rail deployment, fanless operation, industrial temperature ranges, and protocol-heavy IoT work where Raspberry Pi flexibility and industrial interfaces need to coexist in the same device.

Features

• Industrial Raspberry Pi controller: Powered by Raspberry Pi CM4 for flexible edge control, industrial IoT integration, and software ecosystem compatibility.
• Rich isolated interfaces: Includes 2 x isolated RS485, 2 x isolated RS232, 2 x isolated DI, and 2 x isolated DO for field device integration.
• Flexible wireless communications: Supports 4G LTE, LoRa, Wi-Fi, and BLE, with optional module expansion depending on deployment needs.
• Dual Ethernet architecture: Useful for gateway, controller, and edge networking scenarios where upstream and downstream devices need to be separated.
• Industrial deployment design: Fanless enclosure, DIN-rail support, IP40 protection, and wide temperature operation help it fit real field environments.
• Security and reliability options: TPM 2.0, watchdog, RTC, optional SuperCAP UPS, optional PoE, and NVMe SSD support improve robustness for unattended operation.

Specifications

Applications

• Building automation and BMS: Works well with Home Assistant, Node-RED, and protocol-driven building systems that rely on serial and Ethernet field integration.
• Modbus and BACnet gateways: Suitable for Modbus RTU / Modbus TCP bridging and BACnet-related smart building or HVAC control architectures.
• Industrial remote monitoring: Combine RS485, RS232, DI, DO, LTE, and dual Ethernet for telemetry, field data collection, and cabinet-level monitoring.
• Smart city edge cabinets: Useful for traffic, lighting, environment, and utility cabinets that need industrial I/O plus wireless backhaul.
• Energy and facility management: A practical platform for power, HVAC, pump, and facility status monitoring with local control logic and cloud connectivity.

Other Content

The R1125-10 stands out because it combines Raspberry Pi flexibility with industrial control interfaces. That is a very different proposition from a consumer Raspberry Pi enclosure. With isolated RS485, isolated RS232, DI, DO, dual Ethernet, LTE expansion, and TPM 2.0, it is much closer to an industrial gateway or compact controller than a hobby board computer.

It is also a strong fit for protocol-heavy environments. If your project involves field devices, PLC-adjacent serial communication, smart meters, HVAC units, or building subsystems, the R1125-10 makes it easier to bridge those systems into local dashboards, automation logic, or cloud platforms.

Software ecosystem support is one of its biggest advantages. The platform is well suited to Raspberry Pi based workflows using Node-RED, Home Assistant, AWS IoT Core, balena, and other edge orchestration or automation stacks.

FAQ

What kind of product is the reComputer R1125-10?
It is an industrial Raspberry Pi IoT gateway and controller, not a Jetson AI box and not a simple Raspberry Pi case. It is designed for serial communication, remote connectivity, edge control, and field deployment.

What is the difference between R1125-10 and R1124-10?
reComputer R1124-10 is a closely related R1100-series controller, but R1125-10 is the variant that is better positioned when you need the richer communication mix highlighted here, especially around industrial serial interfaces, LTE-ready deployments, and gateway-style edge integration.

How is R1125-10 different from R1025-10?
reComputer R1025-10 belongs to the R1000 line, which is often used when different interface emphasis or system packaging is preferred. R1125-10 sits in the R1100 family and is a strong match when you want dual isolated RS485, dual isolated RS232, DI, DO, LTE-ready gateway capability, and fanless industrial field deployment.

Can R1125-10 be used with Home Assistant or Node-RED?
Yes. The Raspberry Pi CM4 foundation and industrial connectivity make it a practical choice for Home Assistant, Node-RED, and similar automation or edge integration workflows.

Does R1125-10 support Modbus or BACnet scenarios?
Yes. With RS485, RS232, and Ethernet connectivity, it is well suited for Modbus RTU, Modbus TCP, and building-automation style integration where BACnet-related gateways and controllers are needed.

Can I add LTE, LoRa, or PoE later?
Yes. The platform is designed with optional expansion in mind. Depending on the deployment, you can add 4G LTE, LoRa, PoE, UPS, and other functional modules as needed.

Is this product suitable for harsh industrial environments?
It is built for industrial-style deployment with fanless design, IP40 protection, DIN-rail installation, and an operating range of -30C to 70C, which makes it much better suited for field use than a standard consumer Raspberry Pi setup.
