Hello, I am trying to connect my RTK/GPS to the LCD screen. Which 4 points on the LCD do the JST wires correspond with in order for the LCD to receive and display the GPS coordinates? Thank you.
Hello, and thanks for posting in the forums!
The GPS module isn’t designed to be connected directly to a LCD. What you’d need to do is connect the GPS to a micro-controller and have the micro-controller query GPS coordinates from the GPS. Then the micro-controller would format that data and send it onto the LCD for display. It would look something like the picture below.
The red, black, blue and yellow wires are from our [Qwiic Cable - Breadboard Jumper (4-pin) and the cable that connects the GPS to the micro-controller is our [Qwiic Cable - 100mm. You could use any micro-controller you’re comfortable writing code for, but we recommend the [SparkFun RedBoard Qwiic since it already has a Qwiic connector built in.](SparkFun RedBoard Qwiic - DEV-15123 - SparkFun Electronics)](Qwiic Cable - 100mm - PRT-14427 - SparkFun Electronics)](https://www.sparkfun.com/products/14425)
Also, it doen’t show up very well in the picture, but the wires connect to the following pads on the LCD:
Perfect, thanks. I do have the breadboard already and was planning on that configuration.
Pardon me, I actually have the BlackBoard (SPX-15098 RoHS)
That will work too! The BlackBoard was the “experimental” version of the RedBoard Qwiic. The two are virtually identical and function exactly the same.
