Led# Pin - Huawei ME936 Hardware Manual

HUAWEI ME936 LTE 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 lose all data in the module and
remove system drivers. It will also disconnect the module from the network
resulting in a call drop.

3.4.4 LED# Pin

ME936 provides an open drain signal to indicate the RF status.

Figure 3-16 shows the recommended circuits of the LED# pin. The brightness of LED
can be adjusted by adjusting the resistance of the series resistor.
Figure 3-16 Driving circuit
LED# pin output is different from HUAWEI MU733 module, because ME936
integrates a MOSFET inside.
