hello guys please check gdi driver,pinout description on the website and the one comes with the unit different, connector a pin 21 and 14 connector b pin 19 and 25???
Hello,
Thank you for bringing this to our attention.
We’ve identified that the pinout leaflet included with all GDI Driver units shipped up to February 17, 2025 contained an error. While the correct pinout has always been available on our website, the printed leaflet incorrectly swapped the +5V source and Power GND pins.
Please refer to the correct pinout below:
Correct Pinout:
- A14 – Power GND
- A21 – +5V source
- B19 – Power GND
- B25 – +5V source
Incorrect Pinout (from the printed leaflet):
- A14 – +5V source
- A21 – Power GND
- B19 – +5V source
- B25 – Power GND
To help identify the correct leaflet, note that the correct version includes a footnote with our company information, marked with a green frame in the comparison below. The incorrect version does not have this footnote.
If you have been using the incorrect pinout, please update your wiring accordingly. We apologize for any confusion this may have caused.
