TinyDuino Processors & TinyShields / Re: TinyZero with Accelerometer & Wake from Sleep

Hi Steve,
As can be seen in the TinyZero schematic and board files, the INT1 pin of the BMA250 accelerometer is only broken out to a solder pad on the bottom side of the board. This is the small copper circle labeled "INT1" next to the "BOOT" button.
Because of this, a wire would have to be soldered to this pad and then input to the processor via a Proto Board TinyShield. According to the official Arduino documentation for interrupts, any digital pin except for digital pin 4 is usable for interrupt input to the TinyZero processor.
If this is something you'd still like to pursue, I can look into getting some sample code for this.
Hope this helps.
