Product overview
NY-6801-001 Bluetooth module is based on Bluetooth 5.1 version. It is small in size, equipped with display and voice driver. It is simple and convenient to develop. It is suitable for customers with R&D capabilities to add scan code payment functions to traditional devices.
After the user scans the code to pay, the D3 pin of the NY-6801-001 Bluetooth module outputs a high level. After the timer ends, the D3 pin outputs a low level. The MCU can determine whether the device needs to work through the level status of the D3 pin. It can also be made separately into a scan code payment controller to control the power on and off of the device.
