24针定义

1 BOOT_SEL No connection for normal use. Pull-low for loading firmware into empty orcorrupted Flash memory from ROM mode by the module maker.
2 NC No connection
3 1PPS One-pulse-per-second (1PPS) time mark output, 3V LVTTL. The rising edge
synchronized to UTC second when getting 3D position fix. The pulse duration
is about 4msec at rate of 1 Hz.
4,5,6,7 NC No connection
8 RSTN External active-low reset input. Only needed when power supply rise time is
very slow or software controlled reset is desired.
9 NC No connection
10 GND Ground
11 RF_IN RF input, connects to antenna. There is 3V DC bias output for powering active
antenna. Active antenna detection and short protection is provided.
12,13 GND Ground
14,15,16,17 NC No connection
18 SDA I2C interface data signal, 3V LVTTL. Currently unused.
19 SCL I2C interface clock signal, 3V LVTTL. Currently unused.
20 TXD UART serial data output, 3V LVTTL.
One full-duplex asynchronous serial UART port is implemented. This UART
output is normally used for sending position, time and velocity information
from the receiver in NMEA-0183 format. When idle, this pin output HIGH.
21 RXD UART serial data input, 3V LVTTL.
One full-duplex asynchronous serial UART port is implemented. This UART
input is normally for sending commands or information to the receiver in
SkyTraq binary protocol. In the idle condition, this pin should be driven HIGH.
If the driving circuitry is powered independently of S1216, ensure that this pin
is not driven to HIGH when primary power to S1216 is removed, or a 10K-ohm
series resistor can be added to minimize leakage current from application to
the powered off module.
22 V_BCKP Backup supply voltage for internal RTC and backup SRAM, 2.5V ~ 3.6V.
V_BCKP must be applied whenever VCC is applied. This pin should be
powered continuously to minimize the startup time. If VCC and V_BCKP are
both removed, the receiver will be in factory default mode upon power up, all
user configuration set is lost. For applications the does not care cold starting
every time, this pin can be connect to VCC.
23 VCC Main power supply, 3.0V ~ 3.6V DC
24 GND Ground
