"Yes I still have Lea-4T boards.I have pinouts, and full user documentation is available from ublox.Standard board is serial logic level output plus timing pulse output.The standard board is not modified for usb input but you can modify it.Takes some…"
"I have reverse engineered this board.
No need to take the unit off the board its a good useable board as it stands for serial i/o logic levels.
I have a fairly simple modification that will convert it to usb operation powered from usb.

"Yes I have several,
I do need most for my own use but can release small quantities at cost price of £50 GB Pounds plus post and packing. This is less than the cost of the chip alone.
They have logic level serial interface but can be modified to use…"

"Hi,
The units are used but in good working order and as new condition. I have tested many and they all work well on RTKlib.
If you give me your email address I can send a photo, with reverse engineered circuit diagram.
There is a pin header 8 pin (2…"

"Hi,
I have several LEA-4T pcb modules fully populated.
They are £50GBP each with just serial i/o logic levels,
or if you need them modified to run off usb port that would be 75GBP each.
All plus postage.
Its an extremely good price as the chips…"

"The two LEA 4T setup should work.
The uC between the base and PC may be redundant as the LEA 4T has usb outputs.
The uC between rover and RF modem may be redundant too as the LEA 4T has serial outputs too.(might need RS232 level convertor)
The LEA…"
