Pinout for PCF8523 Real-time Clock

Wed Oct 10, 2018 2:35 pm

I'm looking for the pinouts for the female header attached to the the PCF8523 Real-time I2C Clock. The pins on the card itself are unlabled. The accompanying PCF8523 PDF file shows the other models, not the one with the header. The same goes for the PCF8523 pinout page, the model 6-pin female header is not described there.

Which pins are +5V, +3.3V, GND, SDA, and SCL?

The PiRTC is listed on the Raspberry Pi Pinout website
https://pinout.xyz/pinout/pirtc

As seen in the picture
Left Hand Side furthest from the camera connects to pin 1 - 3.3v
Right hand side furthest from the camera connects to pin 2 - 5v
Left Hand Side middle pin connects to pin 3 - SDA
Right Hand Side middle pin connects to pin 4 - 5v
Left Hand Side closest to camera connects to pin 5 - SCL
Right Hand Side closest to camera connects to pin 6 - Ground
