As for the case you could avoid the issue and pickup a food storage container from the local dollar store - they are cheap and easily modded with basic tools. | |

| Jul 20, 2017 at 12:07 | comment | added | Steve Robillard | @TheDiveO Here is a quote from the adafruit page learn.adafruit.com/adafruit-ds3231-precision-rtc-breakout/… "Vin - this is the power pin. Since the RTC can be powered from 2.3V to 5.5V power, you do not need a regulator or level shifter for 3.3V or 5V logic/power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V" It also does not need to be stacked attacj it t the hacker board the same way you would attach it to the GPIO pins that is what the board does. | |
| Jul 20, 2017 at 8:15 | comment | added | TheDiveO | What about 3.3V versus 5V boards? I noticed that the RTC modules (RTC Pi Plus and RTC Pi Zero) from AB electronics UK have level shifters so that other I2C boards can be attached on top. I would suspect that the Adafruit board cannot be stacked. | |
