Beware qwiic connectors on these devices. The qwiic connector itself is a little bit of a dodgy design, as the female connector which resides on the component (the expensive part, typically) has four thin flimsy pins inside that can be easily damaged. On this unit in particular, the angle and position of the socket next to a large flange make it hard to insert the male connector. Just ruined a unit trying :'(

Looking for mechanical dimensions data sheet. Is one available for the new (Qwiic) SerLCD?

Hi SeeCat,We just added this to the documents tab up above. Or you can view it directly here:

Hope this helps and thanks for reaching out!

I just bought another one of these displays and the physical dimensions still don't match the drawing. There's a sticker on the module that says:"2023/12/15ADM1602N1-NS (RGB) -FBS/ZQC OK"
Who is doing the quality checks on these?

Please also add a dimension for the y offset from the header holes to the board edge or mounting holes. There is currently nothing referencing the locations of the header pins along the y axis.

The dimensions on these drawings appear to be incorrect. Most importantly, the 1.4" edge-to-edge dimension is off by about 0.02". Since the mounting hole locations are referenced to opposite card edges, this leads to the calculation of hole-hole distances being incorrect. If you make a footprint based off the dimensions shown in these drawings, the mounting holes will be just a little bit misaligned and you will be so mad.

Qwiic connector poorly placed and too easy to damage
by Member #550832 verified purchaser
The design if Qwiic connectors is a little questionable. The female connector on the component side (the expensive piece) has four very thin metal prongs inside that are easy to mutilate if you're not careful. Typically connector designers prefer to make sure that the component side connector is more resilient because the cables are cheap to replace if damaged. The Qwiic connector on this unit is placed too close to a metal brace that impedes access. I've lost about 50% of my LCD screens to damaged Qwiic connectors so far. Be careful and @sparkfun, make sure you factor resilience into Qwiic 2 if you make an update.
Solid RGB Display
by Codesmith verified purchaser
I've used the I2C and SPI interfaces with this board a few times, and it's always treated me nice. The only downside is that I had a hard time finding documentation for communicating with the board. Ultimately, I ended up code diving through a github repo, which worked well.
cool device man i was not expecting a basic arduino built onto the back
by Member #1686734 verified purchaser
Im currently prototyping a Guitar pickup coil winder a two stage configuration phase one arduino controlled pwm setup with the 6612fng h-bridge motor controller,Success.Next Phase is SerLcd smart Lcd.I need Hall effect sensor and magnet to get motor rpm and turns count.I know i can get code and libraries to pull it off.Gonna order redboard qwiic and cables,header pins etc. to make it happen.If you can imagine you can build it.Truly yoursotisonics
Fan of Qwiic system, SerLCD ok
by Member #1331118 verified purchaser
The SerLCD works fine, but that kind of display has limited uses for me I bought it to play with the Qwiic system. My projects have serious issues with vibration and the Qwiic system gives a nice solid connection for control wires.
Very useful little LCD
by Member #1700855 verified purchaser
Very nice product. I like the Qwiic connection, that the text color / backlight can be changed to indicate status, and that the brightness can also be changed along with the color so that it does not strain the eyes in a dark area. Much better alternative to the traditional Arduino LCDs.
A good 16x2 display
by Member #1612541 verified purchaser
The display is easy to read. It's a good value for the price. The only negative issue was the 3.3V RX data input. Since the unit has a 9 - 3.3V raw DC power input it would be nice if the RX input could handle 5V signals. This was a not a major issue. With a handful of parts (2 diodes, 2 resistors, 1 cap) I was able to construct a data interface that worked OK.
