Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power, ground and RX pins are all broken out to a 3.5mm pitch screw terminal.
SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the backpack to adjust the contrast.
Note: The datasheet incorrectly identifies the PIC as a 16F688, when it's actually a 16LF88. Sorry for blowing your mind.
Dimensions: 0.56" x 1.75"
