पिन
- 1: VSS (GND)
- 2: VDD (+5V)
- 3: V0 (contrast — via a trim pot to GND)
- 4: RS (register select — data vs. command)
- 5: R/W (read/write — tie low to always-write)
- 6: E (enable strobe)
- 7-14: D0-D7 (data bus — only D4-D7 are wired in the common 4-bit mode)
- 15: A (backlight anode, +5V through a resistor)
- 16: K (backlight cathode, GND)
