The MMWB board (MicroMod Wheel Board) allows you to connect daughterboards in MicroMod format and offers unique features.

 

With the NRF52840 daughter board (for wireless configurations), you will have up to 43 inputs/outputs, with the SamD51 board you will have up to 39 inputs/outputs. 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 can work wirelessly with the NRF52840 board and a NRF Dongle.

DescriptionSchematicsPinoutTutorialsDimensionsOptionsAccessories
  • LiPo battery management circuit, including a charging circuit and a 5v boost circuit, which can power a Nextion screen, 7-segment displays, RGB Leds or any other peripheral requiring a 5v power supply.
  • 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.
  • A mosfet to switch the power supply to 3.3v peripherals, which reduces battery consumption when using potentiometers or other sensors.
  • 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 5v power connector to connect to the Simagic or Moza bases (thanks to our Simagic and Moza Quick Releases), the NRF52840 daughter board allowing native radio communication with Simagic bases (inputs only, 32 functions).
  • 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 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 NRF52840
MicroMod NRF52840

Featuring the nRF52840 SoC from Nordic Semiconductor, the SparkFun MicroMod nRF52840 Processor offers a powerful combination of ARM Cortex-M4 CPU and 2.4 GHz Bluetooth transceiver in the MicroMod form-factor with the M.2 MicroMod connector to allow you to plug in a compatible MicroMod Carrier Board with any number of peripherals.

The MicroMod nRF52840 Processor features the Raytac MDBT50Q-P1. This module includes an integrated trace antenna, fits the IC to an FCC and CE approved footprint along with including decoupling and timing mechanisms that would need to be designed into a circuit using the bare nRF52840 IC. The Bluetooth transceiver included on the nRF52840 boasts a BT 5.1 stack and supports Bluetooth 5, Bluetooth mesh, IEEE 802.15.4 (Zigbee & Thread) and 2.4Ghz RF wireless protocols (including Nordic's proprietary RF protocol) allowing you to pick which option works best for your application.

There's also two I2C buses, 2 SPI buses, eleven GPIO, dedicated digital, analog, PWM & PDM pins along with multiple serial UARTS to cover nearly all of your peripheral needs.

 

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

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. This MicroMod SAMD51 comes flashed with the UF2 bootloader.
