MG815+ module has a
voltage output pin with
current limited adjuster. It
can be used to supply
external circuit on main
board. the voltage of this
pin, baseband processor and
storage come from the same
voltage adjuster. voltage
output is 2.85V when power
on. Users should distribute
current as little as possible
from this pin(less than
10mA). Generally, we
suggest this pin is used to
pull up chips’ pin only when
it needs level match.

This section describes the function interfaces and usage of MG815+ modules in details, and provides the
designing sample.

zSerial Port
zSIM/UIM Card Interface
zAudio Interface
zAntenna Interface
Remarks: In the system, the module layout should be far away from high-speed circuit, switch power, power
transformer, large power inductor, or single chip microcomputer’s clock circuit.
4.2 Power and Reset
Figure 4-1 power and reset circuit design reference
zPower design
The module is powered by V-MAIN, and the voltage feature is below:
Table 4-1 Voltage features
Category Min. Typical Max.
Input voltage 3.3 V 3.9 V 4.25 V
D1 is a LDO with low-valid control, making V_MAIN supplies power to module through adjusting R31and
R41 at 3.9V. Modules have very high requirements on power and ground processing, signals must be filtered.
Power ripple needs to be controlled under 50Mv. Do not supply power to any other part of system, otherwise
RF performance will be compromised. Finally, select the power cables with at least 40mil traces during the
layout and keep the integrality of ground line.

MG815+ Module Hardware Design User Manual
zPower ON
The module will be turned off after power-on normally. To turn on the module, firstly put /RESET at high level,
and then provide a 1500-2000mS low level pulse to ON/OFF PIN. /Reset needs to connect an open collector or
open drain gate.
zPower OFF
To turn off the module, firstly provide a 1500-2000mS low level pulse to ON/OFF PIN, after 5s or 6s, and put
/RESET at low level.
zReset
You could turn off the module firstly and then turn it on to reset the module.

20mS 10mS 2S 2S 6S
zV_MSM
There is a voltage output pin with current adjuster, which can be used to supply external power to the board.
The voltage of this pin and the voltage of baseband processor/memory come from the same voltage adjuster.
The voltage output is available only when the module is on. The normal output voltage is 2.85V, and the user
should absorb the current from this pin as little as possible (less than 10mA). Generally, it is recommended to
use this pin to match the level. When the module is off, the output voltage for this pin remains unchanged, but
the impedance is rather high. Therefore, it’s not recommended to use this pin for other purposes.
zOther Advice
In order to make sure the data is saved safely, please don’t cut off the power when the module is on. It’s
strongly recommended to add battery or soft switch like the power key on the mobile phone.
4.3 Serial Port
The module provides 2 UART transceivers and its logic functions conform to RS-232 interface standard. These
