Re: TFT Pins

Hi David, thank you for that. There is no touch screen so i assume XU, XD, YU & YD pins are not used and can be grounded or left open. Any idea about FMARK and RS/AO? It does look like RS/AO 4 Wire on the pinout so I would have assumed it was needed in 4 wire SPI. I am hoping to make an eagle pa...

Hi Olie, I pay around $30 for ten boards up to 100 X 100 mm to be made ie $3 per bare board including postage. Now, if the board size is less than 50mm wide, we can get two boards printed as a panel ie $1.50 per bare board. If I designed a board and had them sent to me to be soldered, then I would a...

Most manufacturing sites have separate buildings, all have lots of metalwork both of which attenuate the signal so hi...
