# ManThink — 门思科技 > ManThink supplies LoRaWAN gateways, sensors and EdgeBus collectors for connecting existing equipment. ThinkLink is its native-LoRaWAN, general-purpose AI-driven IoT platform, supporting LoRaWAN / 4G access, AI operations and micro-app development, with free self-hosted deployment. Product specifications and interface compatibility must be checked against the linked official ThinkLink device manuals. GD6 gateways use ESP32 and connect to an external platform; GD7 gateways run Ubuntu on a quad-core processor with 1 GB RAM and 16 GB eMMC and include the full ThinkLink platform. EdgeBus runs JavaScript collection and protocol logic on supported collectors; a physical interface alone does not guarantee protocol compatibility. GD61 advertised unit price: CNY 298 on Simplified Chinese pages; USD 48 on all other language pages. Confirm the ordered configuration with ManThink. News and articles are available only in Simplified Chinese and English. ## Products and deployment - [ManThink — LoRaWAN Products & AI IoT Platform](https://www.manthink.cn/en/index.md): ManThink offers a native LoRaWAN, AI-powered IoT platform with free self-hosting, cost-effective gateways, a broad sensor range and EdgeBus collectors to modernize existing equipment. - [LoRaWAN gateways selection — ManThink](https://www.manthink.cn/en/products/gateways/index.md): GD6 uses ESP32 and an external platform.
