The Adafruit PiCowbell Adalogger adds microSD storage, RTC with battery backup, Qwiic/I2C connector, and a reset button to your Pico or Pico W. Ideal for flexible data logging and compact project builds.
Ding dong! Hear that? It's the PiCowbell ringing, letting you know that the new Adafruit PiCowbell Adalogger is in stock and ready to assist your Raspberry Pi Pico and Pico W project with handy hardware and datalogging.
This version comes with Pico 20-pin stacking headers pre-soldered on. We also stock the unassembled version in the store.
The PiCowbell Adalogger is the same size and shape as a Pico and is intended to socket underneath to make your next data logging or data reading project super easy. Micro SD card socket? Yes! STEMMA QT / Qwiic connector for fast I2C? Indeed. Real Time Clock with battery backup for accurate timekeeping? Of course!
The PiCowbell Adalogger provides you with:
If using the Philhower Arduino core, the Wire peripheral is already set up to use IO4 and IO5. If using CircuitPython or MicroPython, you'll need to let the code know to look at 4+5 for SDA+SCL pins.
Does not come with a Pico, micro SD card or a coin cell battery. A CR1220 coin cell is required to use the RTC battery-backup capabilities! We don't include one by default to make shipping easier for those abroad.
Raspberry Pi Pico, MicroSD and coin cell battery not included.
