Hello,
All of our product pages include dimensions specs as well as power consumption specs. Dimensions are included as the last image in each product photo reel. Power consumption can be found under Tech Specs, or more in-depth information about power and different power modes can be found from the datasheets included under downloads.
Most boards in the TinyDuino platform are 20mm x 20mm.
From there you can make a few choices to minimize the stack height if you choose to do so. The GPS Tracker Stack in the tutorial includes the TinyDuino, USB TinyShield, GPS TinyShield, and Flash Memory TinyShield. With this stack in mind, the height would match the screw height from the Mounting Kit (
https://tinycircuits.com/collections/accessories-add-ons/products/tinyduino-mounting-kit) to be around 15mm. The GPS Antenna of course takes up some space, but the main stack would be 20mm x 20mm x 15mm.
You could simplify the TinyDuino and USB TinyShield into one board, the TinyZero to save a few mm of height to have around 8-10mm instead. (You can cut the mounting kit screws once installed)
For power consumption, it depends on how often you are polling data, reading and writing data to the flash memory, and if you take into account any low-power modes. I recommend thinking about how long you need to run your project (in hours) and what the likely consumption is in mA. Once you have the number of hours, and the amount of mA the project is likely to draw, you can multiply these to get a mAh approximation. This number can be used to decide which battery works best for your project:
