MS3 Realtime Clock Module

Add accurate time and date stamps to your MS3 datalogs with this Real-Time Clock module. Compatible with MS3 + MS3X. Battery not included.

Add Date & Time Stamps to Your MS3 SD Card Logs

Upgrade your MegaSquirt MS3 system with a Real-Time Clock (RTC) Module to automatically record time and date stamps on your SD card logs. This is especially useful for reviewing logs, tracking performance over time, and organizing tuning sessions.

This RTC module is designed exclusively for MS3, and is much easier to install when used alongside an MS3X expansion board.

Installation Details:

• Solder-on module with included pin headers

• Mounts directly to the MS3X card

• Requires a lithium coin cell battery (not included due to shipping restrictions)

Compatible Batteries:

• BR1216, BR1220, BR1225

• CR1216, CR1220, CR1225

Note: BR-series batteries offer a wider temperature range, ideal for use in cold environments, but typically cost more than CR versions.
