Frequently asked questions
Is this a complete LED controller?
No. This listing is for a GPS accessory module intended for use with the Huidu C16C control card. The controller and LED display are separate system components.
Will it work with every Huidu control card?
Compatibility is listed here for C16C only. Send the exact controller model, board revision and connector details before using it with another card.
Where does it connect on the C16C?
The C16C V0.1 specification identifies a dedicated GPS port. Confirm the module connector, pinout and voltage against the actual card before connecting it.
What positioning accuracy and voltage does the module support?
The original accessory listing does not supply those values. Request the module’s technical data from EagerLED; do not use the C16C controller supply rating as the GPS module voltage.
Is a GPS module specification PDF available on this page?
The original listing did not include a module-specific PDF. The linked C16C controller reference confirms the GPS connection only and does not establish the module’s accuracy, cable length or electrical ratings.
