Industrial-Grade Timing Accuracy: ±5ppm (±0.432 seconds/day) stability with temperature compensation (-40°C to +85°C range). Dual-Voltage Compatibility: Operates at 3.3V or 5V (2.3V-5.5V range), no level shifter needed for Arduino/Raspberry Pi. Complete Calendar Functions: Tracks seconds to years via 400kHz I²C, including leap year compensation until 2100. Battery Backup Support: CR2032 socket maintains timing during power loss (1.3μA backup current; battery not included). Multi-Output & Value Pack: 5x modules (20×15mm each) with 1Hz/32.768kHz outputs for distributed systems.
