* All signals are logic level UART signals (typically 0 - 2.85VDC).
** Use max 4.7kOhm as pull-down which is different to previous product generations from connectBlue.
*** Alternative signal pin recommended to use in new designs (both signal pins should be connected).
The cB-OBS411 module has linear power supplies, which means that the current is constant if the voltage supply is changed.

This signal is multiplexed:
GREEN:Logic Green LED Signal (see the
Status
Active low.
Switch-1: If the level on this pin is pulled-down** the
unit goes back to default serial settings. The Switch-1
input is only active during the first 500ms after startup.
The module will restore all factory settings if both the
Switch-1 and Switch-0 signals are low during start up.
See the Serial Port Adapter AT command
Specification for more information on the Restoring
Default Configuration functionality.
See section
Logic Blue LED Signal (see the
