Standard LCD 20x4 + extras (white on blue) _MAKE_PROTO_SMT These displays require 13 GPIO

These displays require 13 GPIO pins to control

1x 220uF capacitor

and can't play MP3s (MP3 is patented and costs $ to license

so it's super-easy to use

7") diameter flange with mounting holes to make it easy to attach or you can cut it off with a hacksaw and drill/machine as you wish it seems to just be ABS plastic

Standard LCD 20x4 + extras (white on blue) _MAKE_PROTO_SMT These displays require 13 GPIOStandard HD44780 LCDs are useful for creating standalone projects. 20 characters wide, 4 rows White text on blue background Connection port is 0. 1" pitch, single row for easy breadboarding and wiring Single LED backlight with a resistor included, you can power it directly from 5V. If it's too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights Can be fully controlled
