Schematic

You can download the schematic of Raspberry Pi Cellular IoT Application Shield from this Github repository.

LEDs

  • POWER (PWR): When the shield is powered up, this RED led turns on.
  • STATUS (STAT): While the module is powered up by driving PWRKEY(GPIO 11) 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.
  • ENABLE(EN): This GREEN led shows the status of the power regulator of module is switched on or off. By default, the GPIO 26(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 LOW state.
  • NETLIGHT (NETL) : This BLUE led indicates the 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 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 USB port for firmware upgrade.

 

3-axis 12-bit/8-bit Digital Accelerometer | MMA8452Q

  • The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachine accelerometer with 12 bits of resolution. It has user selectable full scales of ±2 g/±4 g/±8 g with high-pass filtered data as well as non-filtered data available real-time.
  • The accelerometer connected to Raspberry Pi via I2C. The I2C address is 0x1C.
  • MMA8452Q’s interrupt pins are not connected.

Raspberry Pi Cellular IoT Application Shield Pinout

12-Bit Analog-to-digital Converter | ADS1015

  • The ADS1015 is precision, low-power, 12-bit, analog-to-digital converter.
  • Raspberry Pi can not measure analog inputs because it does not have internal ADC. However, with this external ADC, the ADS1015, you can read analog values with your Raspberry Pi.
  • The ADC connected to Raspberry Pi via I2C. The I2C address is 0x49.

 

Ambient Light Sensor | ALS-PT19

  • It’s a phototransistor close responsively to the human eye spectrum, light to current.
  • It’s connected to ADC (ADS1015), because of it has analog output and Raspberry Pi can not read it directly.
  • The sensor connected to AIN3 pin of ADS1015.

 

Temperature and Humidity Sensor | HDC1080

  • The HDC1080 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power.
  • Relative Humidity Accuracy ±2% (typical)
  • Temperature Accuracy ±0.2°C (typical)
  • The HDC1080 connected to Raspberry Pi via I2C. The I2C address is 0x40.
  • The heat that produced by when R.Pi heats up may cause the sensor to display a few higher degrees than the ambient temperature.

 

Relay

  • The relay for controlling high voltage and current.
  • Relay control pin is GPIO17. When this pin is HIGH, relay is switched and connected C and NO pins. When GPIO17 is LOW state or unused, it connects C and NC pins.

WARNING! : This small form factor relay and traces can handle up to 60W or 3.5 Amps. Pushing the limits will produce heat and definately harm the circuits and shield. Recommended maximum contact ratings:

  • 12V DC – 3.5A
  • 24V DC – 2.5A
  • 120V AC – 0.5A
  • 220V AC – 0.25A

 

Isolated Inputs

  • Two isolated by optocouplers inputs available on the shield. Recommended max. GPIO voltage level of Raspberry Pi is 3.3V. Reading higher than 3.3V voltage inputs are harmful for your Pi and will definitely destroy the circuits.
  • Upper limit of this inputs is 15V, between 3.3V and 15V is readable. GPIO pins are normally pulled up, when a voltage applied to isolated inputs, GPIO pins goes LOW state.
  • The input’s (sensor, switch etc) ground must be connected to optocoupler’s G input to complete isolated circuit.

 

GNSS and Debug(DBG) UART Inputs

GNSS: This header pins directly connected to BG96 GNSS output. They are not connected to UART port of Raspberry Pi. You should connect to BG96 via USB to receive GNSS data. Thinking that these pins might be needed somehow, so we’ve taken them out as headers.

Debug (DBG): This DEBUG UART port belongs BG96 and used for embedded firmware debugging of module and log output.

External I2C Header

When you need to add an external I2C thing, you can use these I2C connectors. 3.3V VCC and GND pins provided too. It has pull-up resistors.

1-Wire Header

There are lots of sensors which have 1-Wire connection standard (DS18B20 etc.) in the market. 1-Wire connector has VCC, DATA and GND pins. With this pins you can connect easily a 1-wire sensor. Data pin directly connected to GPIO4 and has a 4.7K pull-up resistor.

    Alem

    Is it possible to achieve 3 g network via these boards ?

    • okan

      Hi Alem,

      The module on the shield, Quectel BG96 mainly works on LTE network. It’s only back-compatible with EDGE and GPRS. It doesn’t support 3G(CDMA, WCDMA, GSM, UMTS) unfortunately. For 3G connection, you can try Quectel UC20-G module with our Raspberry Pi 3G-4G/LTE Base Shield V2.

      Thanks for your interest

  2. Rated 5 out of 5

    Ron

    Which countries LTE bands is the module compatible with ?

    • Saeed

      – Supported Bands : Global – B1/ B2/ B3/ B4/ B5/ B8/ B12/ B13/ B18/ B19/ B20/ B26/ B28 and B39 ( for Cat M1 only )
      – eGPRS Supported Frequencies : 850/900/1800/1900Mhz

      This is a global product. You can use it in the country of your choice. If you still can not be sure, you can check the LTE bands used in your country and compare them with the above supported bands.

    Bryan Florkiewicz

    I have project FI and was hoping to connect my RPI to mobile data services and GPS (carputer install).

    Supported LTE bands seem to be B2, B4, B12, B25, B26, B41.

    What all in addition would I need to connect the dots? Is there provided software for the RPI? I have a data sim!

    • Saeed

      Hi. We are developing a python library for using with RPI currently. This library will be ready by the estimated shipping date. The product is the global version and supports various LTE and GSM bands. We didn’t work on Project FI especially but you can use this product with Project FI with a little change on our example codes.

    What carrier in US? Verizon? What are contracts like?

    • Saeed

      Yes, It will work with Verizon too. You may check the Frequency Band of carrier and find out the compatible carrier.
      If you are using Verizon then End user will need to add modules as test devices on Verizon OD.
