Adafruit ChronoDot - Ultra-precise Real Time Clock

The ChronoDot V3 showcases pioneering design during challenging times, built with the cutting-edge MAX31328 temperature-compensated real-time clock chip. It maintains backward compatibility with older models, preserving precise clock accuracy and drift specifications.

Key advancements include enhanced compatibility with solderless breadboards due to its slimmed-down dimensions, ensuring seamless integration while retaining original pin spacing. It also introduces a user-friendly snap-in top access battery holder for effortless maintenance.

Incorporated is an EEPROM chip providing 2 kilobytes of memory, retaining data during power outages—ideal for microcontrollers like STM32 and ESP32 lacking built-in EEPROM. This facilitates data preservation and transport of configuration information or unique IDs.

The ChronoDot V3 stands as macetech’s first product designed entirely with open-source software, transitioning from Eagle to KiCad, reflecting innovation and embracing technological advancements.
