mangOH Green Configuration

Default Configuration

The mangOH Green‘s default configuration is described in 

Table 3-6

.

 

1—Board reset (SW400)
2—Arduino-compatible circuit reset (SW1500)

Default Configuration / Behavior

Notes

Antenna connectors 
(Main, Diversity, 
GPS)

•

U.FL connectors

•

3.3 V bias voltage for active antennas

SMA connectors can be added, if required, by a 
user who is proficient at soldering. For details, 
refer to the mangOH Green schematic available at 

mangoh.io

.

Audio connector 
(CN500)

•

Connected to onboard mangOH codec

•

CTIA/AHJ-compatible headset

Reconfiguration to use an OMTP-compatible 
headset requires soldering.

RS-232 connector 
(CN700)

•

Enabled

•

Connected to primary module’s UART2

LEDs

All LEDs are enabled and will exhibit their default 
behaviors

System reset signal 
(RESET_IN_N)

Held LOW until primary module is fully booted

Peripherals on the mangOH Green are not 
activated until the module is fully booted.

SIM1/SIM2 Detect

•

SIM1 Detect uses physical sensor to detect 
SIM card insertion/removal

•

SIM2—Switch SW401 (position 4) can be 
used to indicate that a SIM is in SIM holder 2:

•

OFF—SIM2 detected

•

ON—No SIM
