Adafruit PiRTC - Precise DS3231 Real Time Clock for Raspberry Pi
The Adafruit PiRTC Precise DS3231 is a high-accuracy, battery-backed real-time clock that plugs directly onto your Raspberry Pi's GPIO header. Built around a genuine Maxim DS3231 with an integrated temperature-compensated crystal oscillator (TCXO), it delivers exceptional timekeeping accuracy — f...
12mm Coin Cell Breakout w/ On-Off Switch
A breakout board with a CR1220 coin cell battery holder, an on/off switch, and 0.1″ pitch breakout pins. Ideal for powering very low-current projects or providing switchable battery backup for a real-time clock (RTC) module. The board breaks out four pins: two ground pins, one switched power pin...
Adalogger FeatherWing - RTC + SD Add-on For All Feather Boards
Add datalogging capability to any Feather board with the Adalogger FeatherWing. This add-on combines a battery-backed real-time clock (PCF8523) with a microSD card socket, giving your project accurate timestamps and local data storage in one compact wing. The RTC communicates over I2C with a 32 ...
DS3231 Precision RTC FeatherWing - RTC Add-on For Feather Boards
A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the m...
