Seeed High Accuracy RTC for Raspberry Pi

This is the High Accuracy RTC (DS3231) for Raspberry Pi—the tiny timekeeper that remembers what day it is when your Pi absolutely does not. SEO appeasement first: DS3231 RTC Raspberry Pi, high accuracy RTC module, Raspberry Pi real time clock. If you’re skimming (obviously): it keeps accurate time, survives reboots, and exists so your logs stop claiming it’s 1970.

Why You Want It

Because “just connect to the internet” isn’t always an option. The DS3231 uses a temperature-compensated crystal oscillator to keep stupidly accurate time, even when your Pi is offline, rebooting, or living its best headless life. Perfect for data logging, automation, robotics, and anything where timestamps actually matter. It’s boring, reliable, and quietly more important than half the stuff on your GPIO header.

Specifications

• RTC Chip: DS3231 (temperature-compensated)
• Accuracy: ±2 ppm (because clocks should be good at time)
• Interface: I2C
• Backup: Coin cell battery support (3V CR1225 lithium cell)
• Voltage: 3.3V / 5V compatible
• Compatibility: Raspberry Pi models with GPIO
• Use Case: Offline systems, logging, automation, robotics
