OLSD V4 Arduino Shield Prototype
OLSD Rev 4
OLSD V4 Arduino Shield Prototype
Specifications:
- Scan Rates: 1 kpps to 30 kpps
- XY Resolution: 12 Bits
- Color Resolution: 5 bits (for a total of 32,768 colors)
- Colors: Red, Green, Blue outputs
- TTL Shutter Output
- Built in test patterns accessible by button.
So what are the big differences between Rev4 and Rev3? Here is the list:
- Rev4 has a XY Voltage reference for a more stable picture.
- Rev4 has more colors! 32k vs. 512
- Rev4 has more free IO pins so you can do more with your arduino!
