TR7220B2S IoT Module — Bluetooth Mesh, Cloud-Ready
The TR7220B2S is an IoT module with Bluetooth Mesh support — built for cloud-connected endpoints where the wireless stack runs on the module and the host MCU only exchanges commands. Firmware builds target Alibaba Cloud, Tuya or a private-cloud deployment, so the module arrives provisioned for your onboarding flow rather than as a generic radio.
Key Specifications

Applications
- Smart home devices — mesh networking across rooms without new wiring.
- Sensors & control hubs — low-power endpoints reporting to the cloud.
- Lighting & automation — Bluetooth Mesh is purpose-built for many-node control.
Integration Notes
Mesh changes the topology. Bluetooth Mesh lets dozens of nodes relay for each other, so coverage grows with device count instead of access-point count. Plan node density, not just per-node range.
Cloud-matched firmware. Tell us the target cloud before sampling — public-cloud provisioning and private-cloud onboarding differ, and the module should arrive with the right build. Samples ship with the matching onboarding guide.
OEM/ODM and Manufacturing Support
The TR7220B2S is developed and manufactured in-house by Shenzhen TrolinkTek Technology Co., Ltd. — R&D, production and sales under one roof since 2005. For programs that need more than the standard configuration, our OEM/ODM path covers branding, packaging, firmware defaults and configuration alignment with your target market, all inside our ISO9001-controlled production process (FCC, CE, SRRC and RoHS documentation available).
Free samples are available so your team can validate compatibility and performance before a volume order.
FAQ
Which cloud should we target?
Alibaba Cloud and Tuya builds are available, plus private-cloud deployments. Choose before sampling so we ship the matching firmware.
Does it need a host processor?
A minimal host MCU exchanging commands over UART is the typical architecture — the wireless stack runs on the module.
