GPS Seri <=> USB Bağlantı Kablosu ( Prolific

quote:

This is the smallest, and thinnest gps module ive seen yet (except for that keychain one).
It is bluetooth and in some cases is packaged with a small lithium battery.


Name/Model:
94V, Also known as Holux M-1200, Diatec G65, others ?

Dimensions:
Width: 18mm
Height: 58mm
Thickness: 5.5mm with shielding and usb socket, 4mm without.

Pictures:

or Large Picture


Information:
The middle is MTK gps chipset, and on the right side (exposed) is the bluetooth chipset and antenna.

The USB connector is used primarily for charging, but is not for connecting to a pc directly for data (only charge)
The USB exposes the serial connections, instead of the appropriate D-/D+ for usb coms.

It is rated to use around 50ma, and under 5ma in standby.


How to install/use:
The thin-ness makes it suitable to install in the space on the left of the lcd panel.
It will fit, but will require cutting of the three little pegs, there will be a slight bulge were the antenna is located, but if you installed a touchscreen, there will not be a bulge (as the touchscreen+screen is thicker than the gps)

Remove the shielding from the GPS chipet, and the USB connector so as to bring it down to 4mm thickness.

A Serial to USB adapter is required. The ideal unit is the prolific PL2303 but the Silicon Laboratories CP2102/2103 and the FTDI chips will also work. Simply connect the TX/RX at the usb connector to the Serial2USB and then that to a USB port.


To save on power, the bluetooth part can be disabled by removing one tiny part OR cutting a trace.
Option 1 - Remove Part
Option 2 - Cut Trace


Let me know if this has been helpful.

Enjoy :-)

Any cable that uses the PL2303 will do, I have not tried the FTDI chipset, but those should also work.
(The CP2102 will not fully work - but not many cables use this chipset)

And remmeber, when using the USB-RS232 cable, connect the GPS' TX/RX to the PL2302, and not the MAX232.
