Logitech G25 / G27 / G29 / G920 or custom shifter adapter. This adapter can be used to make a custom sequential or H shifter.


Uses the principle of an XY position of the lever to process the engaged gear..

Effective Resolution: 12 bits Minimum (4096 positions) on all axes, refreshed and filtered at 250 Hz.

Connector : USB-C

Cable length: 25 cm

An internal calibration is needed on each gear.

This adapter does not require drivers and is natively supported by Windows 10/8/7, Vista 32, Vista 64, XP, 2000, Me, 98, Mac OS X and Linux.

Based on the SamD21 micro-controler, this adapter exposes 6 analog inputs, one serial port, one I2C port and one SPI port (input only). So it can be used to connect several different sensors  : one AS5600, several MLX90393.


Gearbox Calibration
Open a serial monitor on the com port of the board (icon # at the top in Node Blue), You can see the calibration messages in the serial monitor (window at the bottom in Node Blue).
Put the shifter on neutral.
Click on the "Cal" entry of the "Gears" module. The message "Neutral recorded" appears.
Engage 1st gear and click on "Cal" again.
Engage 2nd gear and click again on "Cal", etc ...
When finished the message "Calibration finished" is displayed.
The settings are saved in the non-volatile memory of the board and are restored on each restart.
You can redo a calibration multiple times, by just repeating these operations.
You can also clear the calibration data, go to the "Settings" menu of Node Blue, check "Clear Storage" and upload your project twice in a row.

The Seeeduino XIAO board brings you the power of a SamD21 in one of the smallest form factor. We have installed the Adafruit SamD21 bootloader.

Thanks to Node Blue, this board enables connecting buttonsswitchesencoderspotentiometers,  rotary switchesjoysticks  and various sensors.

By choosing the Bodac option, you'll be able to connect for example 11 buttons instead of 7 (a Bodac allows to connect 5 buttons on one input).

Attention, this board uses an USB-C connector.
