1. Product overview
TB-05 is a BLE5.0 low-power consumption Tmall Genie Mesh Bluetooth module based on
TLSR8250 chip. The Bluetooth module supports the direct control of Tmall Genie and has the
function of Bluetooth mesh networking. The devices communicate through peer-to-peer star
network and Bluetooth broadcast, which can ensure timely response in case of multiple devices.
It is mainly used in intelligent light control, which can meet the requirements of low power
consumption, low delay and short-range wireless data communication.

2.4. Power consumption
The following power consumption data is based on a 3.3V power supply, ambient temperature
of 25°C, and measured using an internal voltage regulator.
All measurements are completed at the antenna interface with a filter.
All transmission data are measured in the continuous transmission mode based on the duty
cycle of the 100%.
