***THIS PAGE IS A WORK IN PROGRESS, WHEN IT IS COMPLETE THIS WARNING WILL DISAPPEAR***

Over the last couple of weeks we have been playing with a lot of LCD Panels from our favorite shop AliExpress. Some have been okay, some have been great (the 0.96“ OLED Panels have been my favorite so far) but this display we are going to look at today is fantastic. Why?

• Its bright and clear.
• It has the viewing angle of an OLED
• The backlight does't bleed through the LCD.
• It's a great size for most projects.
• The driver supports Text, graphics etc.

This is an LCD you can certainly incorporate in to many projects where an LCD is a requirement. Now things appear and disappear on AliExpress quite a lot, so here is the listing description, and if you search the internet for this you are bound to find these LCDs somewhere?

  TENSTAR ROBO 2.4 / 2.8 / 3.5 Inch 240x320 320x480 SPI TFT Serial Port Module 5V/3.3V PCB Adapter T7789V/ST7796S LCD Display

Yes, quite a long description, but searching this will get you one of these LCDs. I recommend you buy at least 2, this makes postage more affordable and means you can have a development and production model.

Here is the wiring diagram, thankfully with a lot of these LCD SPI modules, the pins are in the same order, so once you have a test rig, you can swap displays to try them out (you will need to change the driver also).


Just a note on the Pin Labels on the LCD. This LCD is using the following pin labels.

• GND
• VCC
• SCL
• SDA
• RES
• DC
• CS
• BL

But some LCDs use very different names, here is a table below where you can hopefully work out what other Pin Labes are.
