634 V2.2?


New member
I just purchased a (another) 634 serial LCD display and noticed that its version 2.2. What's the difference/upgrade to 2.2 verses my other 2.0 LCD?

By-the-way, great service folks! I'll be order'n more!

The PCB was changed slightly in v2.2 to accomodate the white LED backlight option, that's all :)

No functional changes in the commands or capabilities.
