Gumstix doesn't seem to have any other customer feedback mechanism, so I guess I'll just post this here. Gumstix needs to be a little more explicit in the fact their North American switching power supply only works at 120 volts. If you plug it into a 240 volt outlet with an adapter, it will blow up. Imagine the not-so-hypothetical case where your team in North America spents months preparing a demo for a customer in Europe, just to have the board blow up in front of the customer. All this because a wide-ranging version of the power supply costs a dollar more? I bought a electric toothbrush for $39 and it has a wide-ranging (100-240 volt) power supply. All other portable electronics have it. Why should I have to carry around a seperate power supply for Gumstix? Dennis |

Unless Gumstix just changed their Web site in response to this, I can't imagine how they could be any more explicit. Sorry about your Overo. We've all smoked our share of electronics.

Hi Dennis Thanks for providing your feedback shown below. The information written on the Gumstix product page for the 5V US power supply <https://www.gumstix.com/store/product_info.php?products_id=70>states: "Power your Gumstix system in the United States and Canada Designed for 120V/60Hz AC input power". If this is the power supply to which you are referring, how could that statement be improved to help prevent the situation described below? Most customers purchase the EU or UK power supply<https://www.gumstix.com/store/index.php?cPath=28_42>when they plan to demo or install their Gumstix products in Europe. Would be interested to learn how often customers wish to use the same power supply both in North America and in Europe.

It's not only Europe... its Australia as well. Our company does the development in both Australia and America... and demo boards are sent between. It would have been ideal for us to have a power supply that did 100V-240V 50/60Hz.

Don, I think you should add the following to make it clear. "For 120V/60Hz AC input power only. This power supply is not suitable for 220-240V input". I have seen other sites that say "for 120V/60Hz input" when the device is capable of the full 90-264 volt 50/60 Hz input. Also, I though the US used 110V? So your statement would seem to preclude use in the US. Perhaps it would be even better to state the full input range as specified on the PSU. Your old CUI supplies were 90-264 volt input and I find that that input range to be a requirement for our usage. Supplying only 120V capable PSUs would mean we have to search for a compatible supply from elsewhere. Remember that other countries, like Thailand, use the US style connector but with 220V/50Hz.

The Overo FE is rated -40 < T < 85C (excepting the microSD slot and radio module). I'd like a version of the Tobi that can match this component rating as closely as possible. Does anyone know offhand if it's just a component or two that hold up the Tobi range? (Ethernet and/or USB jacks, maybe?) I can dive into the BOM, just just wanted to poll in case the answer is easily available. Regards, Greg |

My initial finding from scanning component documentation is that the Tobi operational range is held up by the DVI chip and the Ethernet chip. The Ethernet chip (SMSC LAN9221) can be replaced with an LAN9221i - the exact same pinout and package, only temp-extended from 0<T<70C to -40<T<85C. The DVI chip is 0<T<70C for "operating free-air temperature." Haven't identified if there's an easy drop-in replacement for that one. Fortunately for me I don't use video, and can just power it off anyway. Importantly, both the DC-DC step down power supply and the 70-pin connector to the Overo itself are golden. The 70-pin only to -25<T<85C operational, but that's still pretty good. I've already removed all the connectors from my Tobi, so I don't care, but those all appear to be good as well. If I've missed anything, please let me know.
