USB RTC Type-C Breakout

The USB RTC TYPE C is a highly advanced device featuring an integrated DS3231 circuit with low power consumption and a temperature-compensated crystal oscillator. This ensures precise timekeeping and reliability. To establish USB connectivity in Raspberry Pi projects involving USB, UART (Serial), GPIO, and I2C interfaces, the MCP2221, a USB-to-UART/I2C serial converter, is employed.

The Type-C USB connector used in this setup offers the convenience of reversibility, eliminating concerns about cable orientation during plug-in. Furthermore, it can deliver up to 1.5 Amps of power, providing versatility for various applications.

By incorporating the USB RTC, the system's timekeeping remains accurate. The USB RTC securely stores essential time and temperature data, enabling the creation of intricate devices and products. Whether used with Raspberry Pi, Windows, Linux, or any other operating system, this USB RTC proves to be a valuable addition to a wide range of projects.
