Power Architecture
The COPA mesh module will have a 3.6V Lithium-type battery mounted all the time. It can
use an external power source which it detects through a sense line. The battery is then
disconnected immediately using FETs. External voltage FETs are also controlled from the
MCU, first off then on to make sure the battery and mains do not get connected at the same
time. On-board capacitors will help bridge the small time required for switching.
Voltage coming from the external power source shall be max 3.4V so that it cannot charge
the battery (3.6V) in case mains and battery get connected at the same time (due to any
software/hardware failures).

module is using the power source of another PCB.
