NEW PRODUCTS – Adafruit Real Time Clock Assembled Breakout Boards: PCF8523 / DS1307
These are great battery-backed real time clock (RTC) that allow your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC – but it requires 5V power to work (although we’ve used it with 5V power and 3.3V logic successfully). The PCF8523 RTC can run from 3.3V or 5V power & logic!
The PCF8523 and DS1307 are simple and inexpensive but not high precision devices. They may lose or gain up to 2 seconds a day. For a high-precision, temperature compensated alternative, please check out the DS3231 precision RTC.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
