RasClock – Raspberry Pi Real Time Clock Module V4.2 [Discontinued]
✅ Premium Quality Materials
✅ 90-day money-back guarantee
🛍️ Money-Back Guarantee Included
RasClock is a particularly true real-time clock that plugs directly into the Raspberry Pi and includes a battery backup. The module is installed directly into the GPIO header pins with no wiring or soldering. It uses the 3.3V, GND SDA and SCL pins. The module stays within the outline of the Raspberry Pi and sits lower than video output so can be easilly installed within most cases.
Updated V4.2 – The Rasclock now features an 8 Pin Header input, so boards can be stacked on top!
RasClock uses one of the following chips:
- NXP PCF2127AT
- NXP PCF2127T
- NXP PCF2129AT
- NXP PCF2129T
All of these have the following features:
- Very accurate timekeeping (typically ±3ppm or <2 minutes deviation per year).
- Integrated crystal that compensates for temperature and age.
- A 36mA 3V CR1220 battery will keep the time for around two years if the device isn’t used and considerably longer if it i
