Before discussing an alternative
- Identify the existing HUB40A board and its connector numbering.
- Compare each required signal with the original interface table above.
- Prepare clear photos of the board, connectors and existing connections so the configuration can be checked.
- Contact us with any interface questions before choosing another model, as requested in the original listing.
Frequently asked questions
Q1Which HUB40A pins are marked GND?
The original interface definition lists GND at pins 10, 12, 14, 15 and 16. Pin 9 is CLK, pin 11 is LAT and pin 13 is OE; these positions should not be confused with GND.
Q2Is a similar HUB model name enough to confirm compatibility?
No. The original listing specifically asks buyers to check that the interface definition matches their requirements. Compare all numbered signal positions and the actual connectors before selecting an alternative.
Q3Does this page specify a supply voltage or current rating?
The original page provides the pin signal definition and an interface-matching note. It does not provide a supply-voltage or current rating, so those values should not be inferred from the HUB40A name or the GND labels.
