Hi Trevor,

You could plug an RTC into the exposed headers easily enough, but it’s a little messy.

To have an internal solution you might be able to fit this QWIIC shim ([SparkFun Qwiic SHIM for Raspberry Pi | DEV-15794 | Core Electronics Australia](https://core-electronics.com.au/sparkfun-qwiic-shim-for-raspberry-pi.html)) in the case and use a QWIIC compatible RTC ([Adafruit PCF8523 Real Time Clock Breakout Board - STEMMA QT / Qwiic | ADA5189 | Core Electronics Australia](https://core-electronics.com.au/adafruit-pcf8523-real-time-clock-breakout-board-stemma-qt-qwiic.html)) and a cable ([PiicoDev Cable 100mm | Core Electronics Australia](https://core-electronics.com.au/piicodev-cable-100mm.html)). It’d all be solder free. Teh QWIIC shim is just I2C so you could probably connect any I2C RTC to it.
