VK2828U7G5LF TTL GPS/GLONASS/GALILEO module with antenna and cable
A VK2828U7G5LF GPS module from GMOUSE. Data sheet is available at https://github.com/CainZ/V.KEL-GPS/blob/master/VK2828U7G5LF%20Data%20Sheet%2020150902.pdf
Features onboard ceramic patch antenna. Basic specifications are:
- 28 x 28 x 8.6mm
- 3.3-5V supply at 25-35mA
- TTL signalling, default 9600 baud
- Enable input, 1PPS output plus serial TX & RX with NMEA 0183
- Tracking sensitivity -162dBm, capture sensitivity -160dBm
- Cold start 26 seconds, hot start one second
- 1-10Hz updates
A short 6-way cable with plug is supplied. If you order this, you may receive a VK2828U8G5LF which is an updated version of the module with slightly better specifications but provides the same functions.
