Nice 4x20 character LCD
Using the display without the included I2c interface board. It is compatible with Arduino Libraries. Soldered a female 16 pin SIP header on for using it with jumper wires. The I2c board can also plug into the header. I2c board works good with Arduino LiquidCrystal_PCF8574 library. The display data sheet for a Shenzhen model 2004A is available online. Arrived fast in good condition. Has a bright yellow back light with black characters.

Worked as expected. Price was great.
I got this product (WayinTop 20x4 2004 LCD Display Module with IIC/I2C/TWI Serial Interface Adapter for Arduino Uno R3 Mega 2560 (Yellow Green/2004))Don't forget to adjust the contrast potentiometer on the serial adapter board. When I first ran some test code I thought, why isn't it showing anything. But turning the contrast up quickly showed the text I was expecting.

Clear, brite, and easy to use.
I like these displays. They are very easy to use and seem to hold up over time. I've been using one 24/7 for 6 months now and still looks great.

Great display for embedded applications
Popular LCD display format/configuration but I like this color / contrast much better than the blue/white variety. Crisp characters and color is very easy on the eyes. Nice dimming range with 5k pot in series with the backlight circuit.

DOA
Appears to be dead on arrival.The LCD does not come pre-soldered to the I2C board.Soldered the LCD Board to the I2C board, wired up to my Arduino Mega, powered up and LCD backlight is nice and bright.Load up a sketch and nothing, adjusted the contrast and still nothing.Uploaded an I2C sketch to determine I'm using the correct address, the Arduino is unable to find any I2C devices.This unit appears to be DOA.

Works fine with Arduino. Nice bright yellow/green backlight.
Worked right out of the box. Came with address 0x27 as advertised. I used Arduino library "LiquidCrystal_PCF8574"
