3G modem HSDPA
MOD-USB3G would also work with your laptop and desktop computer - the drivers are located inside the unit.
Note that due to impulse current surges (up to 2A) you might be unable to use MOD-USB3G with other Olimex boards out-of-the-box. You would either need to make hardware adjustements or purchase additional adapter called USB-CAP. For more information refer to the notice in the FAQ section at the bottom of the page.
