USB-B board and serial header 1.4.1 Now the extension headers in 1.4.1 is being used by the usb-b module, but what if you want to use this extension header for something else, like for example a lcd and sd card reader? now you could make a board in-between that breaks out the lcd and serial stuff or you could wire a connector to the USB-B board that connects it to the serial header. Just one catch the usb-b is powered by the electronics and not the serial port on the extension headers. and the 5V+ on the serial header is connected to nada! Now there are two options I can think of and I'm trying to figure out the best. Either take the 5V+ from the usb and connect it to pin that usually connects to 5V on the gen7 electronics like this : USB-Bmod_zps2dc03f0d.png mod_embed_images_loadimage('08161298226e705d8f41224c1f087290', '/forum/thumbcache/fba/6bf/540/865/fac/821/774/9d2/968/777/cf_800x400.png', 'http://i1237.photobucket.com/albums/ff474/terramir/terraweb/electronicsmods/USB-Bmod_zps2dc03f0d.png', 'https://reprap.org/forum/addon.php?181,module=embed_images,check_scaling=1,url=http%3A%2F%2Fi1237.photobucket.com%2Falbums%2Fff474%2Fterramir%2Fterraweb%2Felectronicsmods%2FUSB-Bmod_zps2dc03f0d.png', '', 214606, 800, 400, 'Loading image ...', false); or You could connect 5Vsb to the pin on the serial header, but the catch is that then you might not be able to use a different usb top serial module which you might need to in the future without modding the board.

and well on gen7 lcd/sd hook-up for headless printing as of yet are seriously half baked. maybe in time someone will publish a decent solution like an i2c lcd and the standard miso mosi sd card hook-up]]> terramir Next Wave Electronics Working Group Mon, 03 Jun 2013 07:22:24 -0400 https://reprap.org/forum/read.php?181,214606,214692#msg-214692 Re: USB-B board and serial header 1.4.1 https://reprap.org/forum/read.php?181,214606,214692#msg-214692

Just one catch the usb-b is powered by the electronics and not the serial port on the extension headers. and the 5V+ on the serial header is connected to nada!

That's entirely intentional. Changing that would be a mistake.]]> Traumflug Next Wave Electronics Working Group Mon, 03 Jun 2013 05:21:51 -0400 https://reprap.org/forum/read.php?181,214606,214606#msg-214606 USB-B board and serial header 1.4.1 https://reprap.org/forum/read.php?181,214606,214606#msg-214606 like for example a lcd and sd card reader?
