GPS modules for sale!
We have a few hundred GPS modules that need a good home. Originally built for a tracking project, they’ve served their purpose and now we’d like to offer them to you at a low price. They play very nicely with Arduino, as shown in the photos below. And Raspberry PI too, of course.
Based on the AARLogin GPS-3T module, they use the SiRF III chipset and have a built-in active antenna. Our little PCB also provides some big capacitors to maintain the GPS almanac in case you choose to switch the power off for a few hours – this means a much faster fix when you wake it up.
Connected straight to an Arduino UNO:
Note that the cable assembly comes with it, but the tail ends are unterminated. All you need to know is:
Black – Ground
Red – 3.3V
Brown – Sleep (pull low to power-save GPS)
Yellow – TX
Blue – RX
A really simple Arduino sketch to get started:
Output is standard 9600 baud serial NMEA sentences. There’s an excellent GPS NMEA decoder library for Arduino here which works with this module.
We’re offering them at £12 each. Click here to buy yours. When they’re gone, they’re gone!
