The first article introduced the GD6 open-source LoRaWAN gateway as a product. This one opens up the hardware — the reasoning behind each key component choice, and the engineering trade-offs involved. The GD6’s hardware is not exotic: an ESP32-S3 as the main controller, a Semtech SX1301 or SX1302 as the LoRa concentrator, plus Ethernet, Wi-Fi, […]

ManThink has officially released the GD6 (GD61x series), an open-source indoor LoRaWAN gateway. The gateway is built around an ESP32-S3 MCU with an optional Semtech SX1301 or SX1302 concentrator, integrating Ethernet, Wi-Fi, and optional 4G multi-link backhaul. It covers major LoRaWAN regional bands worldwide — including CN470, EU868, AS923, and US915 — supports the full

Millions of industrial devices — PLCs, energy meters, VFDs, sensors, thermostats — communicate over RS-485 buses every day. Getting that data into a cloud platform is the prerequisite for any digital transformation initiative. But RS-485 has no native networking capability. The market offers three approaches: Approach Representative Form Core Mechanism Wired Serial-to-Ethernet RS-485 to TCP/IP

Industrial IoT is not short on data—PLCs, energy meters, sensors, and VFDs already speak RS-485. What they lack is a reliable, low-power, long-range wireless bridge to the cloud. KC25x LoRaWAN DIN-Rail RS-485 Data Concentrator is built exactly for that. Ultra-Compact, Fits Anywhere Measuring just 69.0 × 25.0 × 25.0 mm, KC25x snaps onto standard DIN rails

Covering 29+ verified field devices across metering, industrial sensing & control, building & environment, and smart agriculture. Search by name, model, or protocol — every device comes with complete integration documentation. Why a “Device Catalog”? In IoT projects, the hardest part isn’t the technology itself — it’s figuring out “can I connect this device?” In

With the rapid development of industrial digitalization, smart buildings, and energy management systems, more and more devices need to be connected to IoT platforms. From environmental sensors and smart meters to industrial instruments and automation equipment, massive amounts of field data need to be collected, transmitted, and managed efficiently. However, real-world IoT deployments often face

1. Project Background The office building includes multiple subsystems: Existing issues: 2. System Objectives The goal is to build a low-maintenance, scalable monitoring system enabling: 3. System Architecture Built on ThinkLink, the system consists of four layers: 1. Sensor Layer 2. Edge Access Layer (DIN-rail DTU) 3. LoRaWAN Network Layer Based on LoRaWAN: 4. ThinkLink

In traditional IoT deployments, system architecture is often fragmented: sensor vendors provide devices, communication modules require third-party integration, and platform systems must repeatedly adapt protocols and data models. This fragmented approach leads to long deployment cycles, high integration costs, and complex on-site commissioning. ManThink has developed a true full-stack IoT product ecosystem based on years

1. Overview KS32 is a LoRaWAN-based dry contact input acquisition device designed for industrial and infrastructure monitoring applications. It provides 6-channel digital input (DI) interfaces, enabling direct acquisition of dry contact signals from field devices and transmitting status data over LoRaWAN networks. The device is designed to address a common challenge in industrial retrofit scenarios:

RS485 and Modbus RTU remain widely used in industrial automation, building management, energy monitoring, and smart utility projects. While these devices are reliable and cost-effective, they often face challenges when organizations attempt to integrate them into modern IoT systems. Issues such as extensive cabling, high installation costs, and limited remote management capabilities can slow down
