  • *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)

Info
  • 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.

10UART TXBG96 RXThis pin functions as the serial data output from the module for UART communication
11GPIO 17BG96 POWER DISABLEBG96 3.8V Power regulator control. Normally pulled-down, when this pin drove to HIGH, BG96's power will cut off.
12GPIO 18BG96 RESETThe module can be reset by driving GPIO 18 to a LOW-level voltage for a time between 150ms and 460ms.
13GPIO 27USER LEDActive HIGH, to switch on the USER LED, the pin's state should be HIGH.
15GPIO 22USER BUTTONThis pin normally pulled-down to ground. When the button is pressed, pin switches to LOW.
16GPIO 23BG96 STATUSThe STATUS pin is used to indicate the operation status of the BG96 module. It will output HIGH level when the module is powered on.
18GPIO 24BG96 PWRKEYThe 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.
Warnings
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:

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.

Solder Jumper(SJ)

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.

When you observe the HAT, you will come across some solder Jumpers marked as SJx (SJ1, SJ2, SJX etc)

These solder jumpers are either connected or disconnected by default. These can be used to enable or disable the default use case. These SJ are provided for the cases where the specific GPIO are conflicting with the users requirement. Disconnecting the jumpers may lead to loss in some programmable feature. For instance, Cutting SJ2 which is connected to the power key will take the ability to power on and off from the software. As a result user would need to use the physical button.

Disconnecting:

Cut the narrow trace between the middle of these solder jumper with a utility knife.

Connecting/Reconnecting:

Solder the jumper to connect the traces.

The SJ details for each version of the board are mentioned below.
