Was about to say this was going to be a quick video... it's not. This is a full detailed walkthrough of how the trigBoard works on a hardware level. That clever low power circuit keeping the standby power down to less than 1uA is analyzed in depth including the TPL5111 timer functionality and how it plays with everything else on the board. Thought it would be a good idea to pull out the logic analyzer to show you what's really going on here. I think there's a lot to learn from this board that can be used on many many low power projects.
