M2M6270T User Guide

Interface board connection directions:

a. DC jack

The adapter must be in the range 5V~6.5V and can supply over 1.5A.

b. DC power switch

Switch to right direction for supplying VBAT to the module.
Otherwise, switch to left direction to turn off VBAT.

c. USIM socket

The purpose of the socket is to insert SIM card.

d. Micro USB

This USB has some main functions:

(a) Download firmware.

(b)Send AT command.
(c)Trace GPS log

e. Adaptor board Conn.

This is for the purpose of connecting main board and adaptor board.

f. SD card socket

The purpose of the socket is to insert SD card or some SDIO interface
module.

g. Audio in (mic)

This is a differential input microphone.The audio generator can generate
a tone to 6270T module through this jack for testing.

h. Accessory board Conn. (HPGP)

This is for the purpose of connecting main board and accessory
board(HPGP).

i. Power key

Press this key to power on/off 6270T module.

j. RS232 Conn for UART&GPIO24~GPIO27

This is a stacked DSUB-9 connector. The upper one is for QSC6270T
UART and the other is reserved for GSBI UARTs in the future (like 9x15).

k. RS232 Conn for GPIO21,GPIO22,GPIO34&GPIO35

These DSUB-9 connectors are reserved for GSBI UARTs in the future (like
9x15).

l. PCM CODEC input

The analog audio pass through this jack and encoded by PCM
CODEC(TLV320AIC1110).

m. PCM CODEC output

6270T PCM signals are decoded by PCM CODEC(TLV320AIC1110) and
Output from this audio jack.

n. Audio output(Speaker)

This is analog audio output path of 6270T module

o. Battery Conn

This is battery connector which supplies VBAT to 6270T module.

A-2. JUMP setting

A-2.1 VREG_IN:

JP2.1 short to JP2.2  Translated to 5V/3.3V/1.8V/1.2V from adapter.
JP2.2 short to JP2.3  Translated to 5V/3.3V/1.8V/1.2V from battery.

A-2.2 Battery charger switch

JP19.1 short to JP19.2 Use internal (QSC6270T) charger function.
JP19.2 short to JP19.3 Use external (charger IC on main board) charger
function.

A-2.3 BATT_THERM to Charge IC

Short this JP4 to connect BATT_THERM to external charge IC on main
board.

5/20

M2M6270T User Guide

A-2.4 BATT_THERM to Fuel Gauge IC

Short this jump(JP5) to connect BATT_THERM to Fuel Gauge IC
thermostat.
To avoid BATT_THERM read interference, if short JP5, suggest to remove
JP6 jump (Disconnect BATT_THERM with QSC6270T).

A-2.5 Battery thermostat switch

JP21.1 short to JP21.2 Use 22kΩ resistor as battery thermostat for testing.
JP21.2 short to JP21.3 Use the real external battery thermostat.
