Hello I'm trying to get some advice on trying to keep the Arduino zero board alive when the power is unplugged. I'm running the RTC real time clock onboard the arduino zero board. Well It's a adafruit tinker board small one. It runs the Arduino zero bootloader. The problem I'm having is that if the power is removed then the real time clock is gone. Would there be a easy way of keeping it going to keep the clock running somehow?
