Thanks Gordon, Yes that's the GPS attached too. I had it on for about 10 minutes and it isn't dropping. But last time I watched it it's quite happy to find more and more satellites. I don't actually have a problem with it trying to get more accurate location data.
The datasheet does say it has some 40mA or lower after about 12 minutes of tracking. I will test this tonight.
Something I couldn't work out about the SD adapters (I didn't look for long) is some have about 15 pins and others 7. Do some boards give a nice SPI interface and others break out the the pin such that I'd have to address everything myself/a fs driver.
As I understand it SD and is surface mount type is just a very basic chip that lets you address the flash directly, unlike fully driven pen drives or SSDs.
