The TB-05 is a Bluetooth 5.0 module designed for smart lighting products with support for mesh networking. It can be directly controlled by Tmall Genie without the need for a gateway, making it an excellent choice for IoT and smart home applications. With AT transmission firmware, it allows for secondary development and supports multiple sleep modes, making it highly versatile and energy-efficient.

Features

  • Bluetooth Mesh Networking: Enables device-to-device communication through a peer-to-peer star network.
  • Gateway-Free Tmall Genie Control: Directly controllable by Tmall Genie without an external gateway.
  • 6 PWM Output Channels: Frequency of 1 kHz with brightness adjustment range of 5% ~ 100%.
  • Energy Efficient: Supports multiple sleep modes, with a deep sleep current as low as 0.8 μA.
  • Compact Design: SMD-20 package with 1.1 mm pin spacing, compatible with both semi-hole pads and through-hole pads.
  • Additional Features: Includes small night light functionality and wall switch-based color temperature adjustment.
