Page 21: Power On/Off Control
The Tile can be externally switched on/off by an user-supplied power switch on the 3V3 power inputs. When a Tile has been turned off, power should not be restored until more than 1 second has elapsed. Additionally, if a unit does not respond to software commands, power off the module, wait for at least 1 second and then power it back on. -
