The MMWB H board (MicroMod Wheel Board Hub) allows you to connect daughterboards in MicroMod format and offers unique features. Ideal for USB configurations with or without USB screens (like Vocore), it proposes filters and protections on USB input and output lines. To use it with a USB screen, you'll have to associate it with the Samd21J Hub daughter board, that includes a USB HUB.

 

It can also be used for USB configurations without screens, with a SamD21, SamD21J or SamD51 daughter board.

 

 

You'll find below in the description tab a table with the different daughter boards to help you choose the one corresponfing to your needs. All boards can work via USB or native connection with Fanatec or Thrustmaster bases. The management of Nextion screens, RGB LEDs and 7-segment displays is done using the SimHub software and needs a NRF Dongle to work wirelessly.

  • Filters and protection circuits for USB input and output.
  • 4 precision pull-up resistors on analog inputs to connect Bodacs, which allows you to put up to 20 buttons in addition to the other 39 remaining inputs.
  • 8-pin JST 2.0 connector to connect natively to Fanatec bases (using our SRM Quick Release), and also to Thrustmaster bases (also possible by a 2x3 dupont connector).
  • 2 x 6-pin JST 1.5 connectors for connecting 2 Fanatec APM paddles or any other system with up to 2 digital paddles and one analog paddle per port.
  • A 2 pin JST 2.0 5v power connector to connect to the Simagic or Moza bases (thanks to our Simagic and Moza Quick Releases).
  • A 4-pin JST 2.0 connector to easily connect an aviation connector for steering wheels operating in USB or a panel mount USB connector for wireless wheels (for battery charging or for firmware updates).
  • A 4-pin JST 2.0 connector to easily connect a USB screen like a Vocore (you'll need a Samd21J Hub daugher board).
  • A USB-C connector to program the board or connect a USB extension.

Axis Calibration
 
To reprogram the board or to calibrate the axis, you need to install Node Blue. It is recommended to reprogram the board to benefit from the latest version.
 
Depending on the project you are using, you will have to use one of the following 2 methods:
 
  • Calibration with the serial monitor
 
You will need to have a  "NodeBlue Interface", "SimHub Interface" or "Nextion Interface" module in your project.
 
Attention : if the USB port is used for a Nextion, leds or other Simhub interfaces, you'll need to disconect SimHub in order to free the serial COM port.
 
In Node Blue, open a serial monitor on the board (at the top of the window, select the correct COM port and click on the # icon), You can see the calibration messages in the serial monitor (window at the bottom in Node Blue). You must also display the "Controllers" tab at the top right. Select "Raw" as display mode.
 
 
For each axis:
  • Click on the "Cal" input of the analog input module, the sensor module (eg AS5600) or the "Range" module. The module name can be "Accel", "X", "Y" or "Z", or something else depending on the application. Once cal is pressed, a message appears in the serial monitor window. Follow the instructions.
  • Once the calibration is complete, double click on the module to change the low and high deadband parameters. Check in the controller tab that when the axis is completely released the value is 0 and when it is fully released the value is 65535. Adjust the dead zones if necessary. Click on "Invert" if you need the axis to work in an inverted way. 
 
Once the calibration of all axis is complete, save the project so that the settings are saved, either by using the "Save project" menu or with the CTRL-S key combination. If the project is read-only, use the "Save As" menu and choose another name.
 
 
  • Manual Calibration (if the USB Virtual serial port is not present or used by another non compatible module)
 
In the "Controllers" tab at the top right. Select "Raw signed" as the display mode.
 
 
For each axis:
  • Double-click on the analog input module "X", "Y" or "Z" (or any other name depending on the project) concerned by the axis.
  • Position the axis to the minimum, copy the value displayed in the controller tab (adding a small margin), in the "In Min" parameter of the module.
  • Position the axis to the maximum, copy the value displayed in the controller tab (by removing a small margin), in the "In Max" parameter of the module.
  • change the low and high deadband parameters. Check in the controller tab that when the axis is completely released the value is 0 and when it is fully released the value is 65535. Adjust the dead zones if necessary.

 

Once each axis has been done :

  • Save the project so that the settings are saved, either by using the "Save project" menu or with the CTRL-S key combination. If the project is read-only, use the "Save As" menu and choose another name.
  • Select the com port among those detected (disconnect any other detected boards to be sure to program the board you want).
  • Upload the project to the board ("Upload" button).

 

The settings are saved in the flash memory of the board and are restored at each restart.

MicroMod SamD51
MicroMod SamD51

With a 32-bit ARM Cortex-M4F MCU, the SparkFun MicroMod SAMD51 Processor Board provides  an economical and easy to use development platform if you're needing lots of power with minimal working space. With the M.2 MicroMod connector, connecting your SAMD51 Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). The SAMD51 is one of the most powerful and economical microcontrollers available so to be able to add it to your MicroMod Carrier Board is a huge advantage for your project!

The ATSAMD51J20 utilizes a 32-bit ARM Cortex-M4 processor with Floating Point Unit (FPU), running up to 120MHz, with 1 MB of flash memory, 256 KB of SRAM with ECC, 6 SERCOM interfaces, and other features 

 

We have fixed a hardware bug on this board in order to be able to use the ADC for radiometric measures (potentiometers, etc.).
