HUAWEI MU736 HSPA+ M.2 Module
Hardware Guide
As the RESET# pin signal is relatively sensitive, it is recommended to install a 33
pF capacitor near to the M.2 pin.
Triggering the RESET# pin signal will lead to loss of all data in the module
and the removal of system drivers. It will also disconnect the module from
the network resulting in a call drop.
3.4.4 LED# Pin
MU736 provides an open drain signal to indicate the RF status.

Figure 3-15 shows the recommended circuits of the LED# pin. The brightness of LED
can be adjusted by adjusting the resistance of the series resistor.
Figure 3-15 Driving circuit
LED# pin output is different from HUAWEI MU733 module, because MU736
integrates a MOSFET inside.
