Our workhorse PLT-1001v4 driver board has learned some new tricks! Now, with new software (version 3.02), it can do even more.

• Displays text in many fonts and can effortlessly scroll text
• Take TTL serial commands to draw circles, lines and rectangles 
• Built up a frame with these commands for instant display
• Supports multiple displays of the same type without having to change firmware
• Change the text scrolling speed using the scrollspeed command  
• Support for different types of LED matrix displays that have the EN enable pin either active high or low.
• Make your text neat and fresh with textr and textc commands -- right justified and centered text
• Control the brightness of your display!  

All you need to update the firmware is a USB to serial converter and the Windows Screamer bootloader program.
