iic i2c twi spi 1602 lcd module port for arduino quotation

I de-soldered and removed the backpack from the LCD board and carefully cut the trace between the two pins of the jumper with a razor blade. That restored the function of the jumper and allows dimming of the backlight with a PWM pin from a microcontroller, etc.

If I can come up with some thin sharp tool that fits between the backpack and the LCD, I should be able to cut that annoying trace without having to desolder the backpack.

The surface mount transistor adjacent to the jumper is the driver for the LED backlight. Might be a Disconnecting the base and PWM it might be an option too.

You may return most new, unopened items within 30 days of delivery for a full refund. We"ll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.

Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.

This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
