nRF5182
name：
WT51822-S2
The WT51822-S2 module is a data transparent transmission module. It adopts Nordic’s BLE Bluetooth MCU integrated SOC chip nRF51822-QAFF. It integrates the low-level low-power Bluetooth 4.0 standard protocol, and the module interface is a standard UART. The interface has built-in interrupt output prompt function. When the module receives data transmitted by paired Bluetooth, it will output a high-level prompt signal to notify external devices. At the same time, the module is equipped with a hardware enable pin, which can be used when data transmission is not required. By setting the enable pin high, the function of serial data transmission is disabled, thereby reducing the power consumption of the system.
