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.

You will solder 16 pins
I didnt read the description carefully enough. I missed the words "this kit"...meaning that you will have to solder 16 pins on interface adaptor to connect it to the LCD module. Im not doing that. It's going back to Amazon. The 1 star rating has nothing to do with the performance of the module, it's because I made a mistake and bought a kit. Also, there are absolutely NO instructions of any sort. 2 boards show up in 2 different wrappers. There are no identification markings (on the wrappers). I guess if you need to know which is which or what to do with them, then you ought not buy this product or any like it, soldered together or otherwise.

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"
