@NeverDie You have a point. The TPL is also simpler.
But bless the developer. Yes, I was trying to hype his product. I forgot to mention that doing this current test was really easy because this thing just worked... right out of the box (really, out of the anti-static bag.) Rarely have things work so quickly for me. Even the TPL required fumbling.
So if sleeping is the objective and timing isn't really important, then the TPL it is. But if configuration settings, Bluetooth, ADC, I2C, SPI and timing are relevant, then the Trigboard is the way to go.
