DS1307 AT24C32 RTC real time module

It can be used to control the microprocessor of the Arduino AVR PIC system and others, or as a digital potentiometer rotating the rotary encoder can be counted in positive and negative, depending on the direction of rotation; with the button of the rotary encoder can be reset to its initial state, which starts counting from 0.

This product is a Bluetooth module BLE 4.0 UART without adapter, low energy with serial transceiver.
Logic level conversion circuit. No external level of 5V is needed to become a 3.3V level.
The power input port is protected against the anti-circuit, to avoid the inverted accidental power plug, which leads to the module burn
