Warnings

  • ① LTE B25 will be supported on BG96 with R1.2 hardware version.
  • *Under Development

Connection Types

USB: If you don't want to occupy the UART port on the Raspberry Pi, you can plug the HATvia micro USB to Raspberry Pi after stacking it*. You can start to send and receive AT commands, transmit data, output GNSS NEMA, debug and upgrade firmware over the USB connection. It supports USB drivers for Windows, Linux, and Android. Details can be found in the drivers section.

UART: The UART pins will be available to use, with 3.3V power domain, directly connected to the UART port of Raspberry Pi. It can be used for data transmission and AT command communication with 115200bps baud rate. The default data frame format is 8N1 (8 data bits, no parity, 1 stop bit). This port does not provide GNSS data. The GNSS data can be gathered only over the USB.

Note

  • *If you want to use HAT as standalone without stacking on Raspberry Pi, it is possible if you short the 5V-VBUS headers then plug the HAT via micro USB cable.

Data Speeds

  • Cat M1: 375Kbps (Downlink), 375Kbps (Uplink)
  • Cat NB1: 32Kbps (DL), 70Kbps (UL)
  • EDGE: 296Kbps (DL), 236.8Kbps (UL)
  • GPRS: 107Kbps (DL), 85.6Kbps (UL)

SMS

Enhanced Features

  • GNSS: GPS, GLONASS, BeiDou/Compass, Galileo, QZSS
  • Firmware Upgrade: via USB interface
  • DFOTA: Delta Firmware Upgrade Over the Air
  • Processor: ARM A7 Processor, with 3MB Flash and 3MB RAM Available for Users

Warnings

  • For the best working condition, use at least a reliable 2A adapter or power source.
  • We don’t recommend the usage of long and low-quality micro USB cables between Cellular IoT HAT and Raspberry Pi. It may cause data and power loss.

Antenna Requirements

Antenna Type Requirement
GNSS* Frequency range: 1559MHz ~1609MHz
Polarization: RHCP or linear
VSWR: < 2 (Typ.)
Passive antenna gain: > 0dBi

Active antenna embedded LNA gain: < 17dB
LTE/GSM VSWR: ≤ 2
Efficiency: > 30%
Max Input Power (W): 50
Input Impedance (Ω): 50
Cable Insertion Loss: < 1dB
(LTE B5/B8/B12/B13/B18/B19/B20/B26/B28, GSM850/EGSM900)
Cable Insertion Loss: < 1.5dB
(LTE B1/B2/B3/B4/B39, DCS1800/PCS1900)

Warnings

  • *It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use of
    the active antenna may generate harmonics which will affect the GNSS performance.
  • Antenna connectors are uFL(IPEX). If you want to connect an SMA antenna, you need the use an u.FL to SMA interface change adapter cable.

Active GNSS Antenna

*The HAT is designed with a passive GPS antenna circuit by default. Using an active antenna needs enabling the external LDO by shortening normally-open solder jumper(SJX) on the GNSS RF trace on the board nearby GNSS antenna connector.

Pin Descriptions

Pin Number BCM Pin Pin Name Description
3 GPIO 2 SDA I2C Serial Data
5 GPIO 3 SCL I2C Serial Data
8 UART RX BG96 TX This pin functions as the serial data input to the module for UART communication.
10 UART TX BG96 RX This pin functions as the serial data output from the module for UART communication
11 GPIO 17 BG96 POWER DISABLE BG96 3.8V Power regulator control. Normally pulled-down, when this pin drove to HIGH, BG96's power will cut off.
12 GPIO 18 BG96 RESET The module can be reset by driving GPIO 18 to a LOW-level voltage for a time between 150ms and 460ms.
13 GPIO 27 USER LED Active HIGH, to switch on the USER LED, the pin's state should be HIGH.
15 GPIO 22 USER BUTTON This pin normally pulled-down to ground. When the button is pressed, pin switches to LOW.
16 GPIO 23 BG96 STATUS The STATUS pin is used to indicate the operation status of the BG96 module. It will output HIGH level when the module is powered on.
18 GPIO 24 BG96 PWRKEY The module can be turned on by driving the pin BG96 PWRKEY to a HIGH-level voltage more than 500ms then pulling it down. You can apply the same process to power down to the module if it already powered up.

Warning

All data pins work with 3.3V reference. Any other voltage level should harm your HAT or RPI.

Notes

  • *Typical value with USB and UART disconnected.
  • **Sleep state with UART connected and USB disconnected. The module can enter into a sleep state
    through executing AT+QSCLK=1 command via UART interface and then controlling the module’s
    DTR pi
  • *Idle state with UART connected and USB disconnected.
  • These values refer to the consumption of only the BG96 module, not the whole circuit at all. With the LEDs and regulation losses, it may rise to 25mA.

LEDs

  • POWER (PWR): When the shield is powered up, this RED led turns on.
  • ENABLE(EN): This GREEN led shows the status of the power regulator of the module is switched on or off. By default, the GPIO 17(ENABLE) pin is pulled up by hardware and the regulator juices the module. To shut down the regulator, this pin needs to be driven to the LOW state.
  • STATUS (STAT): While the module is powered up by driving PWRKEY(GPIO 20) to HIGH state or pushing the PWRKEY button, this RED led turns on.
  • USER (USER): The GREEN user-led can be controlled by driving the GPIO 27 pin.
  • NETLIGHT (NETL) : This BLUE led indicates the connection status of the module. When the connection is established and data is being transmitted/received, this led will blink at special intervals. Please find the following chart for details:
State Network Status
Flicker slowly (200ms ON/1800ms OFF) Network searching
Flicker slowly (1800ms ON/200ms OFF) Idle
Flicker quickly (125ms ON/125ms OFF) Data transfer is ongoing
Always high Voice calling

Buttons

  • USER: This push button connected to GPIO24 and pulled up HIGH state by default. When you push the button, you will read the LOW state from GPIO24.
  • PWRKEY: When BG96 is in power off mode, it can be turned on to normal mode by pushing the PWRKEY button for at least 500ms.
  • BOOT: Pushing this button can force the module to boot from the USB port for firmware upgrade.
  • RESET: The RESET button can be used to reset the module.

External I2C Header

When you need to communicate with an external electronics over the I2C, you can use these header footprints. The SDA, SCL pins already have 4.7k pull-up resistors.
