I have "Power Supply, 12V, 3.0A, IEC320-C8" power supply, so PS is not an issue. I understand than net5501 boards could get enough power (current) from PS, but I'm not sure if miniPCI card could about 1.35 A (with 3.3 V !) from boards. For DC it is about 4.5 W !!! For such small interface as miniPCI. I don't find any spec with electricity limitation for miniPCI on 5501 board. Thanks Good I have no PATA/SATA disk, only CF :). You right - this card has very high transmit power this could be law issue. But good news is that this card may works perfect (due Atheos 802.11 chipset) with aircrack ;-).
Bad news is that one seller of SR71-A wrote me that this HW works only with dedicated Ubiguiti boards (the LS-SR71 board) and IS NOT supported with any other hardware. Strange because Ubiguiti state on own web: "Operating System Support: Linux". thanks again. _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
