2.8 Reset Methods

The mangOH Yellow supports hardware and software resets of the entire board or certain components of the
board, as shown in

Figure 2-27

The mangOH Yellow also will switch off automatically if operating under battery power and the battery voltage
drops below 3.1V, and will remain off while the battery voltage is < 3.6V.

For detailed specifications showing how full or partial resets are enabled, see the mangOH Yellow schematics
available at

mangoh.io/mangoh-yellow-resources-hardware

Figure 2-27: Reset Methods

Table 2-11: Reset Methods

Board Components to Reset

Reset Method

Entire board, including CF3 module (WP or HL)

Press Reset button (SW401) to trigger the module signal RESET_IN.

Note:

RESET_IN can also be triggered by the IoT connector (CN601) if a

hardware modification is made to populate resistor R630. Refer to the
mangOH Yellow schematic for details.

All components except CF3 module

Use an API command to trigger the module signal LOWPOWER_RESET.

IOT Expansion Card

Use an API command to trigger the CF3 module signal

GPIO_IOT0_RESET.

Wi-Fi+BT module

Wi-Fi Reset—Not currently supported.

BT Reset—Use an API command to trigger the CF3 module signal

GPIO_BT_RESET.
