This is unlikely. Because it happens regularly on 5 different devices. The battery is connected to the cable by welding, and to Teensy 4.1 by soldering without mechanical contacts. Those devices that have a GPS receiver, after long periods of...

Indeed, I did not conduct a "clean" experiment. I measured the voltage with different devices. This is most likely a mistake. Now I measured the consumption current, it is about 29 μA. With such consumption, the CR123a battery should lose only...

I measured the voltage on the RTC battery with one channel of the oscilloscope. With the other channel I monitored the supply voltage of 3.3 V during the normal switching on of the device. The supply voltage increased in a smooth exponential. I...

Thanks Mark for the advice on setting the time. I also have to set the date. This is a much more elegant solution than mine. I'll gladly use it. Also thanks to jmarsh for the advice. Now I'll definitely switch to an external RTC. However, I...

I have at least 5 devices and all of them have this problem. Accuracy of several minutes is practically not scary, but the RTC completely loses settings. At the same time, before switching on, I check the voltage on the battery, everything is...

Hello everyone! For several years now I have not been able to solve the problem of the loss of the current time by the real-time clock built into Teensyy 4.1. In those devices that are equipped with a GPS receiver, I correct the time according to...
