Description: This is a very large serial graphic LCD. The Serial Graphic LCD backpack is soldered to the 160x128 pixel “Huge” Graphic LCD and provides the user a simple serial interface to a full range of controls.
Besides writing text, this serial graphic LCD allows the user to draw lines, circles and boxes, set or reset individual pixels, erase specific blocks of the display, control the backlight and adjust the baud rate. There’s also a reverse mode that allows the screen to operate blue on white instead of white on blue. Additionally, all source code for the ATMega168 processor is compiled using the free WinAVR compiler and is free for downloading.
Dimensions: 4x5x0.65" (102x129x17mm)

I have been extremely satisfied with the previous products I’ve bought from you guys… so you can imagine my shock and bewilderment when I bought this screen and the backpack came damaged. Below are 2 attached images:
If you look closely, I’m not sure if there’s supposed to be a connector or something there but it seems it was ripped out prior to packaging because it’s nowhere in the static bag. Also, the entire copper pad for the Vin is missing. The copper traces for Rx and Vin are broken.
I have tried soldering those copper traces, but it’s a dead Backpack. So there’s something else wrong with it. The screen still works when I use the parallel interface. it’s an inconvenience… but it works. I was initially going to order two of these screens but changed my mind last minute… maybe this is a sign I made the right decision.
Hi, Looking at your pictures, it looks like the screen was damaged in transit. Likely it was smashed or force was applied to have caused the damage as shown. Please contact our support team. We’ll be happy to help you resolve this issue.
The serial interface is straightforward so it was quick to start controlling the screen with a simple python scrip. Inside, the screen looked great and I really like the big size. But outside you can barely see the letters and the viewing angle is only about 60 degrees from normal. I wanted to use this outside so I think I will try an OLED display or an e-ink display next.
This product has a bit of a troubled past. the Serial backpack had a pretty lousy code for quite a while causing plenty of errors during simple serial communication. this lasted for quite some time
Nowadays however the code has been vastly improved and it works pretty great. Great if you want to give your project a nice big easy to controll screen.
I’m quite sure I’m doing everything right here. Adjusted the contrast potentiometer to its min and max values, but event at the best calibration, pixels are too bright. Image only gets nice if you tilt the LCD 45 degrees - then you get a perfect blue background with white pixels.
