2.6" 37pin ILI9342 wiring Gaboze-Pocaio / Round-2

Post by tps99 » Wed Jun 03, 2020 10:32 am

Hi,

I have a Gaboze-Pocaio / Round-2 PCB which has the usual LCD 51 pin pads.
Which pins of the 37pin LCD ribbon cable should be wired to which pads on the Round-2 PCB?

Thanks

Well, you didn't get an answer a year ago, and I probably wont get one either :D

I'm trying to figure out if it's possible to attach the 37pin 2.6inch screen the BOM file helpfully points at ( https://nl.aliexpress.com/item/32861496981.html ), to the 51pin connector on the Gaboze-Pocaio / Round-2. The connections are not too complicated. 39 pins are either GND or just not connected at all. 6 pins are "power", leaving six "other" pins.

left to right (Gaboze-Pocaio Round2 PCB)
-------------
Pin 1 to 4 - unconnected
Pin 5 - GND
Pin 6 - IOVCC }--joined to VCC
Pin 7 - VCC }--joined to VCC
Pin 8 & 9 - unconnected
Pin 10 - RESET
Pin 11 to 28 - GND
Pin 29 - CSX
Pin 30 - RSX
Pin 31 - WRX
Pin 32 to 41 - unconnected
Pin 42 - SDI
Pin 43 ----- BS0}--joined to VCC
Pin 44 ----- BS1}--joined to VCC
Pin 45 ----- BS2}--joined to VCC
Pin 46 ----- BS3}--joined to VCC
Pin 47 LEDA
Pin 48 to 51 - GND
==============

The ones that I'm stuck on are SDI and VCI. The 37 pin doesn't have SDI? and on the 37 pin, does VCI need power? I'm probably just going to have to trial and error it, but maybe somebody knows?
