Base HAT vs Base Shield V2

  • Base HAT does not require to choose its header type, long, short or no header. It comes with an SMD header acceptable and short&long headers, you can stack it whatever you want.
  • You can completely disconnect the power of HAT by driving GPIO26 to a HIGH-level voltage state. Then it starts to consume below 1 milliamp typically.
  • USER LED is added and light up if you drive GPIO27 to HIGH.
  • USER BUTTON added and pulled-up by default. When you push the button, you can sense a LOW level from GPIO22.
  • Now, it can be called as a HAT not shield, complies with HAT requirements by Raspberry Pi Foundation.
  • It has a slot for Pi Camera on board for easy mount.
  • The location of the micro USB connector realigned. It is better now to use the right-angle micro USB cable included in the package without bending it too much.
  • There is a new footprint for a surface mount right-angle JST connector on the bottom of the board for external 5V sources. It is not soldered by default.
  • All GPIO pins used by HAT connected to Raspberry Pi IOs via normally-close jumpers. You can easily cut the connection on the bottom of the board if the pin occupied by another HAT you stacked on it.

 

Migration to Base HAT from Base Shield V2

The new HAT has better power circuitry and features than Base Shield V2. It is pin-to-pin compatible, your old setup will work with the new Base HAT right out of the box. You need only check the following points:

  1. On the Base Shield V2 the GPIO26 connected to PERST-PCI pin of the miniPCI pinout. It lets you reset the modem by changing the state of this pin. Now, this pin used for enabling/disabling of the power of HAT, that means you can reset the modem by cutting its power and enabling then.
  2. Two new IO pins, GPIO27 and GPIO22 populated by USER LED and BUTTON respectively by this new HAT. If you need these pins by your project, you can cut the jumpers on the bottom of the board easily. (SJ5 for the button, SJ6 for LED)

 

Key Applications

  1. Video/Music Streaming
  2. Large Data Downloads and Uploads
  3. LTE Dongle/Router
  4. Mobile Internet Hotspot
  5. High-speed GPS Tracking
  6. Real-time Environmental Monitoring
  7. Smart City & Agriculture Applications
  8. Smart Parking
  9. Security & Asset tracking

 

Header Options

Raspberry Pi Base HAT Header Options

The HAT comes with built-in SMD header acceptable and two headers with different lengths included in the package by default. You can choose the right version for the project and stack and use it immediately without soldering it.

  1. Long Header: If you plan to attach another Raspberry Pi HAT or add-on board on top of the Base Shield, you will definitely need this variation. Also, using GPIOs with jumper cables is possible with these male headers. If you need to stack another shield on top of Base HAT or still need to use GPIOs, the long header will be useful.
  2. Short Header: At the case you need the HAT as the slimmest possible, the short header will work like there is no header added length above the Raspberry Pi.
  3. Without Header: If just the plugging Base HAT via micro USB cable to Raspberry Pi is enough for you, or you’ve already attached a bulky shield on Pi, doesn’t need UART communication or IOs, headerless HAT works greatly. For knowing what you missing without headers, take a look at the Pinout Diagram of the HAT, these pins will be unconnected.

    Base HAT Documentation

    If you have any other questions, just let me know and I’ll be happy to help.
    A thank you, but no answer in the documentation. The purpose of my question, is to know if the material is correctly sectioned. Because if the connection between the RPI and the hat allows only 1mbps in UART and 2mbps in USB, it is useless to have a card which can transmit 1200mbps / 750mbps. Hence my question on the ratio (in mbps) of data in RX and TX which passes between the hat and an RPI3B + or RPI4B, in USB and in UART (GPIO). Thanks for your feedback.
    Answered by the admin

    Oh, sorry. I understood your question better now.

    The data connection between HAT / Shield and Raspberry Pi when connected with Micro-USB is 480 Mbps. Modules are generally below this value. With the 4G / LTE Module (e.g Quectel EC25) you can reach 150Mbps downlink and 50Mbps uplink data rates.

    I hope this helps you.
    A OK thanks for your answer. so with USB is 480 Mbps. AND with UART (GPIO) ? because the main interest of the hat is the UART connection. Thank you by advance. Best regards.
    Answered by the admin

    We generally recommend using it with USB. If you are going to use it from UART, it depends on your setting(Baudrate). If you use USB, UART will not prevent this.

    Best regards.

    Hi,

    This pin(pin35) is used to turn Airplane Mode on the module, by pulling it HIGH.

    Yes, it is not in airplane mode because you did not pull it high.

    The Base HAT is recommended to use with USB for maximum speed. The UART will limit the speed.

    The UART of Base HAT is not connected, to use it, the SJ7 and SJ8 need t be soldered individually.

    Hi Martijn,

    Base HAT does not support voice dialing, but the module supports.You can use AT commands to make call (Audio codec is not present so you can't send or receive voice.). The call is possible to trigger an event but cannot listen to anything.

    Hello,

    Thanks for the feedback on your experience.

    1. The Base HAT is not only compatible with the Quectel modules but also with the Telit and U-blox modules. Other than Quectel, this pin is used as 3.3V. Therefore, connected to work compatible with other modules. Quectel has confirmed that the 3.3V connection to this pin will not be a problem.

    2. Yes, it is not connected, instead it can turn the HAT on and off completely.

    3. This feature is not available in our software. You can do this with AT commands. Please activate to use. Don't forget this.

    Hello,

    node = cellulariot.CellularIoTApp()

    initializes ttyS0, while the Base HAT has no connection between, over serial by default.

    you will need to change it as follows.
    node = cellulariot.CellularIoTApp(serial_port="/dev/ttyUSB2")

    Then you can use to send AT commands.

    NOTE: All the functions of the library cannot be used.
