SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi

Works great! Thanks

Worked perfectly for my esp32 project, shipped quickly, and I have nothing bad to say about the product!

works as intended and of good quality

Other than the fact that there was no link given for the library, and none was found on the Sunfounder website (only for the non-I2C version of the display) it performs very well. I used a library found on the official Arduino website for an I2C display, and it works. I would definitely buy again!

Excelente producto

Using this was a breeze! It just took 4 wires and the I2C LCD library and I was good to go. I'm using it with an Arduino Pro Mini 5V. I love that the I2C module comes pre-soldered. A quick hint on using this: if you find that it sometimes prints out garbage characters, especially when jostled, try adding a capacitor connected across VCC and GND. I had this problem and found that doing this solved it. Adding a capacitor keeps the flow of current steady even when the voltage dips.

It interfaced perfectly with my "Arduino UNO REV3_A000066". I'm able to display the date, day, time and temp in fairly large letters. I like the contrast adjustment that helps the text stand out clearly. I've been using it for several months now and, so far, so good.

This display works well with the i2c interface connected to an Arduino. However, I found that the 2 backlight enable pins on the interface board were shorted together even without the jumper in place. This made it impossible to adjust the backlight brightness, which was too bright for my application. After much difficulty, I was able to separate the interface board from the 1602 display board. This allowed access to the bottom side of the interface board where I was able to confirm that there was indeed a PCB trace connecting the two backlight jumper pins. Cutting the trace restored the original intent of this jumper, allowing control of the backlight level (with the addition of a series resistor). Be sure to check this if your jumper has no effect on the backlight. Beware that to correct this takes a lot of time and patience as you have to unsolder all 16 pins that interconnect the two boards.

Afficheur de qualité, la lisibilité des caractères est bonne ainsi que le contraste. La qualité des soudures est excellente. Je conseille ce produit

Funciona perfecto y fácil de implementar.

An improvement of the previous LCD 1602 I had. This one comes with only 4 connector pins from the I2C module. The I2C module has also been pre-soldered already to the LCD. Great buy for me.

Accoppiato ad Arduino. Buon contrasto e buona illuminazione.

You get more than what you pay for.
