Anonymized customer question:
We’re interested in purchasing Puck Mini and have a few questions:
Puck Mini uses our UbiSwitch Module internally. The closest four-port bare-board setup is that module paired with UbiSwitch Baseboard Mini, which provides four gigabit ports on PicoClasp connectors.
Could you share why you’re looking for a bare-board alternative? That’ll help us recommend the right option.
There’s no physical on/off switch or reset pushbutton on the boards inside Puck Mini. It starts when input power is applied. You can switch power externally or cycle it to restart.
For the LEDs, do you need them physically absent, or is the goal simply no visible light? What’s the reason for removing them?
Anonymized customer follow-up:
We’re still interested in Puck Mini, but would also like a board-only alternative for evaluation and to understand the design better in case we encounter issues.
The LEDs would be useful on engineering units, but less useful on units built into a product. We want them physically absent to save power. How much power would removing them realistically save?
We also wouldn’t connect the UART pins or the fourth Ethernet port. What would the estimated maximum power draw be?
For board-only evaluation, UbiSwitch Module + UbiSwitch Baseboard Mini is essentially Puck Mini without the chassis, just with different connectors. If you plan to use Puck Mini in the final product, it’s probably best to test with its cable too. You could order a Puck Mini and remove it from its housing for evaluation.
Our rough estimate is that removing the LEDs would save around 0.05 W. How many units would you need initially, and what annual volume do you expect? That’ll help us look into a custom version for you.
With three active gigabit ports, we estimate around 4.3–4.4 W. This is a rough estimate; the rated maximum remains 4.6 W. Leaving UART disconnected won’t make much difference.
