Maestro A2200 GPS Module
No one commented, so I assume no one else has tried them so far.toggle quoted messageShow quoted text
I got a couple of the A2200 modules and tested them out.
Unfortunately, unlike many GPS receivers they don't fire up straight
after switch on. They have an on/off pin that has to be strobed in
order to switch on - so only useful when used in conjunction with a
However, once strobed on, they start delivering NMEA 4800 baud data
and can achieve lockup from a completely freezing-cold start in 30
seconds. After that, warm start is a second or two. NMEA data at
3.3V logic levels so can go straight to a uController running at 5V,
but the PPS is only at 1.8V - which quite isn't so useful. An NPN and
using inverted PPS solves that one.
However, for the price and ready availalbility from Farnell, they're very good..
They 'claim' to have an anti-jam capability against CW jammers -
which I'm very sceptical about. Haven't done any testing yet, but
that claim certainly needs investigating.
