LILYGO T-FH interface sensor is the abbreviation of female header, main function is that there is no need for a connecting line, and it can be extended directly through the 2.0-pitch busbar. Simple and beautiful.
There will be T-FH with different functions. this one is mainly used for LILYGO T5-4.7 inch ink screen, as a low-power Bluetooth wake-up module.
Many developers are wondering why they have used ESP32-based wifi/Bluetooth functions, and need to extend a low-power Bluetooth module?
Answer: In the battery scenario, although the ESP32 has Bluetooth, it must be used when it is awake and cannot be used when it is sleeping.
The power consumption is intolerable for the limited power of battery power. Of course, it is not necessary to use the battery scenario. Use this module. .
For example, the ink screen sleeps and wakes up on demand, and the micro cameras sleeps and wakes up on demand.
