2.2 BOARD overview
| CN100 | Micro SIM card socket |
|---|---|
| CN101 | 7pin 2.54mm header interface |
| CN102 | USB interface |
| D100 | NET LIGHT indicator(Green) |
| J104 | LTE ANT |
| J105 | GPS ANT |
| TP109 | 3.3V |
| TP100 | 1.8V |
*2.3 PCBA dimension: 3737mm.**
Pin definition
Note: VCC
range is from 2.7V to 4.8V. Over 3V is recommended.
TXD /RXD are 3.3V TTL level which can be directly connected with 3.3V MCU.
After the PWRKEY continues to pull down more than 12S, the system will
automatically reset. Therefore, long-term grounding is not recommended for
PWRKEY pin.
3.1 Pin definition of 6pin connector
| Pin name | Pin number | Mark on PCB | Description | Comment |
|---|---|---|---|---|
| SLEEP | 0 | S | control module into sleep mode | Connect with DTR via Q102 |
| GND | 1,6 | G | GND | |
| VCC | 2 | V | The power supply | 2.7V-4.8V |
| PWRKEY | 3 | K | System power on/off | Active low. Power on/Power off/Reset |
Function. After the PWRKEY continues to pull down more than 12S, the system
will automatically reset. Therefore, long-term grounding is not recommended
for PWRKEY pin.
TXD| 4| T| Transmit Data| 3.3V TTL Series data Output
RXD| 5| R| Receives Data| 3.3V TTL Series data Input
3.2 How to use TXD and RXD (Default baud rate is 115200bps)
How to test the BK-SIM7080 by AT command via UART
4.1 Installing LTE antenna, GPS antenna and SIM card for BK-SIM7080
Board. (Note: Please use IoT card, not normal Mobile phone card.)
4.2 Feed power supply to VCC pin, and pull low PWRKEY pin for 1-2Second and
release, The Green LED begin to blink.
4.3 GREEN LED indicator, Blink quickly shows un-registration network，Blink
slowly shows registration successful. (Note: Should confirm whether
correct SIM card is inserted)
| NETLIGHT pin status | Module status |
|---|---|
| 64ms ON. 800ms OFF | No registered network |
| 64MS ON, 3000ms OFF | Registered network (PS domain registration success) |
| 64ms ON, 300nis OFF | Data transmit (PPP dial-up state and use of data services |
such as internal TCP/FTP/HTTP)
OFF| Power of or PSNI mode
4.4 Open serial software and choose right serial number, Baud rate as below,
please keep “SendNew” selected:
How to test the BK-SIM7080 by AT command via USB
(NOTE: USB Power cannot be present with VCC POWER simultaneously)
5.1 Remove all connection on CN101 7pin connector, Power up the SIM7080
Breakout board only via USB, and pull PWRKEY pin low for 1-2Seconds to power
on sim7080 module, Install SIM7070_SIM7080
WIN7_WIN10_USB_Driver_V1.00.rardriver following the computer indication. The
computer will show as belows, it means that the driver is installed
correctly.
5.2 Select AT
Port 9001, 115200bps and SendNew, you can repeat all command in Item4.4.
