Does anyone have any information on this board? I bought a couple to take the LEA-4T off - it's a long story but I need the phase measurements and the UBLOX 4 series is fine - but it occurs to me that I may be taking it off this board just to put it on a board with similar features. The problem is, I have no information on this board.
So, if you know anything about this board, I'd appreciate hearing what you think.
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.
A few track cuts and wire links and some tricky soldering.
I have a supply of these.
They are almost certainly the circuit board used in the evaluation kit but I can't say for sure.
In any case they are equivalent in function. I can supply pinout and equivalent circuit information with them. If you buy the basic board from me I can supply details how to do the usb modification.
everything you need is on the board, antenna short circuit protection, backup capacitor ( although you might want to put a supercap there instead), voltage regulator for the LEA-4T chip. supply decoupling etc
I also got one of those boards, would you mind sharing the pinout of the header connector ?
I would also be interested in the USB modification, do you have any insturctions or photos on how the mod is performed ?
HI, I just ordered a board that looks exactly like this. Do you know what type of antenna connector it has? Thanks
My board has an SMB male connector.
If you purchase through me I can supply unlimited assistance in reverse engineering, connecting to usb, setup commands RTKlib, best antennae, use of choke rings etc.
I can also supply the board modified to run direct off usb (signal plus power)
I can also supply the antenna, antenna cables and choke rings.
Anthony - Thanks for your help last summer with these cards. I've been very successful and need additional boards. Can you provide a list of what you offer and, if possible, a price list.
Anthony is a great source of information on these boards. With his help, I have put a couple on Sparkfun serial - USB cards. It kind of hurts my head to pull serial i/o off the board and convert it to USB when the board will do it without the card but I already had the cards and couldn't justify buying more.
FYI - the board works great and provides excellent RTK results.
What type of antenna are you using with your boards to get good RTK resuts?
Sorry, Vast - didn't see this until now. I'm using GPS 53335 L1 antennae. Works great!
just a fyi for others searching this

i ordered that board as well from china but havent received it yet. i guess that with an ftdi cable and the drivers from the ublox site i ll be ok to connect them to u centre on windows or i missed somethind?
