3.1.1 Power

The default option of the smoke detection module board is to install a 9-V battery in the battery socket. Once the power is on, the module starts operation automatically.

The user can also use an external 5-V supply to power the board. To achieve this complete the following:

  • Remove the 0-Ω resistor at R15 location and install a 0-Ω resistor at R14 location
  • Connect GND and 5-V connector to the external ground and external supply, respectively
