Hi, can someone share the schematic of the GT2560 Rev A+? I only found the schematic for the GT2560 A, I like to use ICSP to upload the firmware and i'm not shure if the pin layout is still the same. Or could at least someone confirm that the pin layout on the Rev A+ is the same as on Rev A? Pin lay...

that is the 1/2A fuse for the USB. I briefly looked at the schematic, I think the fuse is there to more or less protect your PC but I think it's not needed since most USB ports limit themselves to 500mA anyways. To get you going you can solder in a fast acting 500mA fuse. A local hardware store or ...

Hi William, thx for your answer. The reason for my problem is that there is missing a small SMD part on the board at position F2 right behind the USB connector. This causes that the USB connection is not working and without a working USB connection I can't upload the necessary firmware to the new an...

I don't have any resistor to try but I bridged both solder points with with a screw driver and the effect was that the green power LED behind the USB connector was shining after connecting the USB cable with my laptop.

Maybe there was a fuse at some point which was not needed later so they removed it, i don't know. It should have been a backup, I found it on the board schematic, but without any info about the backup. This fuse protects the board against the USB power input without having this fuse or a bridge bet...

You can try replacing the crystal with another one if your LCD is two rows of rectangles. And if your LCD is working fine now,then it maybe the FTDI chip was broken,you can attach the picture of the FTDI on your board(as clear as possible,i mean the numbers on it). In addition,there is another way ...

The board was exchanged but there is an other problem with. I'll open a new thread which can be found here: https://www.geeetech.com/forum/viewtopi ... 18&t=19130

By the way, the customer support from my dealer was perfect until now and I hope the "new" problem could be fixed.

@cosmith,
does your config also fit with some small adaptions for the I3X Pro?
I'm also interested to setup the mesh leveling with a cap sensor on my X Pro.

@Stoned_Stew,
your Arduino version(1.8.1) does not work with the downloaded firmware.
Try it with Arduino 1.0.1 that should work.
