Description Seeed Studio reComputer R1035-10 is a fanless industrial Raspberry Pi IoT gateway and controller built on the Raspberry Pi Compute Module 4 platform. It is designed for protocol-heavy industrial and building deployments where RS485 communication, wired networking, wireless backhaul, local edge logic, and long-term reliability matter more than desktop-style computing. This model combines 3 x isolated RS485, dual Ethernet, HDMI 2.0, SIM card support, M.2 NVMe expansion, and optional 4G, LoRa, Zigbee, PoE, UPS, and TPM 2.0. That makes it a strong fit for BMS, BAS, iBMS, Modbus gateways, BACnet-related integration, remote monitoring, industrial telemetry, smart energy management, and distributed facility control. Because the R1035-10 belongs to the reComputer R1000 family, it is much closer to an industrial gateway than a generic Raspberry Pi enclosure. It is intended for edge deployments that need stable communication, field integration, and software flexibility in one compact platform. Features CM4-based industrial gateway: Raspberry Pi CM4 with 8GB RAM and 32GB eMMC in this SKU for stable edge processing. Strong serial integration: 3 x isolated RS485 makes it especially useful for Modbus RTU devices, meters, controllers, and building systems. Flexible wireless connectivity: Supports 4G LTE, LoRa, Wi-Fi, BLE, and Zigbee with optional modules. Deployment-friendly industrial design: Fanless cooling, IP40 protection, wide temperature range, and DIN rail or wall mounting support. Security and reliability options: Optional TPM 2.0, optional UPS, high-accuracy RTC, and hardware watchdog help with unattended operation. Software ecosystem ready: Well suited to Node-RED, Home Assistant, AWS IoT Core, balena, and industrial integration stacks.

BACnet and facility integration: Suitable for controller-level deployments that sit between field devices, dashboards, and supervisory systems in BACnet-style building environments. Remote monitoring and fleet management: LTE, LoRa, wired Ethernet, and local storage help with distributed device monitoring and industrial telemetry. Industrial and utility gateways: Useful for pumps, meters, power systems, HVAC, and other cabinet-level edge integrations. Product List reComputer R1035-10, system installed 1x Mounting Brackets 2x DIN Rail Bracket 1x Set of Bracket Screws 1x 16-pin Terminal Block for DIO 1x 19V Power Adapter, power cord sold separately 1x 2-pin Terminal Block Power Connector 1x Other Content The R1035-10 is one of the better choices in the R1000 line when RS485 matters most. Its 3 isolated RS485 channels make it especially useful for building systems, serial meters, PLC-adjacent integration, industrial gateways, and multi-device bus deployments. It also works well as a software-centric edge gateway. The Raspberry Pi ecosystem makes it practical for Node-RED, Home Assistant, AWS IoT Core, balena, FUXA, and N3uron based deployments. If you need local AI experimentation as well, the R1000 ecosystem also supports computer-vision oriented workflows and edge logic while still keeping the gateway form factor and industrial connectivity.

The biggest advantage is the 3 isolated RS485 interfaces. That makes it especially suitable for Modbus RTU, building systems, industrial telemetry, and serial-heavy field deployments. How is R1035-10 different from R1125-10? R1124-10 and the broader R1100 family are more interface-rich in some industrial control directions, but R1035-10 is the better fit when you specifically want the R1000 gateway form factor with 3 isolated RS485 channels. Can I use R1035-10 with Home Assistant or Node-RED? Yes. It is a very practical platform for Home Assistant and Node-RED, especially when local automation needs to talk to serial devices, meters, or field controllers. Is R1035-10 suitable for BACnet or Modbus gateway projects? Yes. With isolated RS485, dual Ethernet, and Raspberry Pi software flexibility, it is well suited for Modbus and building-integration scenarios where BACnet-related systems are part of the stack. Does the product include LTE or LoRa modules in the box? No. Those are optional modules. The platform is designed to support them, but the modules themselves are not included unless specifically bundled. Can this be used in harsh industrial environments? Yes. The device uses fanless cooling, IP40 protection, and supports -30°C to 70°C, which makes it much better suited for field deployment than a regular Raspberry Pi setup. What if I want to compare the wider reComputer lineup before choosing? The reComputer collection is a good place to compare the R1000, R1100, Jetson, and industrial lines from a deployment perspective.
