Adalogger FeatherWing - RTC + SD Add-on for All Feather Boards
The Adalogger FeatherWing adds timestamped data logging to any Feather with a real time clock and microSD storage.
A Feather board without ambition is a Feather board without FeatherWings! This is the Adalogger FeatherWing: it adds both a battery-backed Real Time Clock and micro SD card storage to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight!
Check out our range of Feather boards here.
This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You get both an I2C real time clock (PCF8523) with 32KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS). Tested and works great with all of our Feathers.
Does not come with a micro SD card. 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, but we do stock them so pick one up or use any CR1220 you have handy. If you're not using the RTC part of the FeatherWing, a battery is not required. If you need a precision RTC, check out our DS3231 FeatherWing
For pinouts, wiring and code example that will run on all Feathers, check out the tutorial guide.
Features
- Battery-backed Real Time Clock (PCF8523) with 32KHz crystal
- microSD card socket for data logging
- Compatible with all Feather main boards
- I2C RTC connection and SPI microSD connection
- Requires CR1220 coin cell battery for RTC backup (sold separately)
- microSD card not included
- Stacks on top of Feather boards with Feather Headers
- Ideal for datalogging applications
Specifications
- PCB: 50.8mm x 22.9mm x 1.6mm
- Weight: 5.1g
Revisions History
- As of June 6, 2017 - we now ship a version with a slightly different power supply setup that reduces RTC brownouts. It is otherwise code and hardware compatible
- As of June 22, 2022 - we have changed the crystal in the Adalogger to a smaller package and may ship either a SOIC or HVSON version of the same RTC chip. Functionality and pinout are identical!
