Now that the boards have arrived, I thought I’d post a few pictures of the batch being made and tested:
This is a simple breakout board for Sharp’s Memory LCD display family (LS013B4DN02, LS013B4DN04, LS013B7DH03, LS013B7DH06, LS027B7DH01 and LS044Q7DH01). Those are the parts known at the time of the writing, though more models are coming out all the time. So far Sharp’s been keeping very consistent interface and there is a fairly high chance the board will work with all of them. In a table below is a list of displays I am aware of on the US market. Models needing 5V boost are marked accordingly.
The board brings all pins to a 0.1″ header and provides necessary caps and resistors. Revision A2 adds an optional boost converter for those wanting to run 5V display from sub 3.3V supply which is needed on color version, 2.7″ and larger screens and also some of the older ones.The footprints are there, but parts are not populated to save cost on the base version. A version with boost is now also available. This is an open design under CC BY SA license.
Very excited to be part of the growing tech indie community called tINDIE! My store is at https://tindie.com/shops/kuzyatech/ and carries all the things I design for sale. At the moment I have Sharp LCD breakouts, LM317 power supply kits and the Kicky Dude kits
I’ve been tweaking my Sharp LCD breakout board to make it suitable to more users. The latest iteration is off to the board house, but here is a quick preview:
I have a few of the LCD breakout boards available for sale.
Schematic diagram is here .
Note: the header is included but not soldered, to make life easier in case you need to run wires to the board instead. Sharp LCD is not included. You can get the 5V version (LS013B4DN02) from Mouser. Part number is 852-LS013B4DN02. The boards were tested with Arduino Uno driving the LCD directly with 5V IO. That seems to be fine for the display according to the Sharp Datasheet.
First solder the header or wires as needed, then attach the display using a small piece of double sided tape and connect the flex. See my previous post for pictures on how a fully assembled board should look like, and this post for testing details

Sure, there is not much to test there- two connectors and a few caps. But the idea was to make the breakout so I can play with the display and see what I can design it in. For a while I stared at the datasheet, figuring out what it needs to be driven, then on a whim went to Google for an existing driver library for it. A library by craftycoder came up. It is based on Adafruit’s Arduino GFX library and includes an example that was more than enough to test the display. So I dug out my Arduino Uno and set things up:
My boards from OSH arrived a while back, so here are some pictures. The next step is getting the code running to test the display, though I may try feeding it some serial goodness from Bus Pirate as a test. So far it appears that the first test run of DipTrace tools and OSH Park service went pretty well!
As promised, some 3D rendering pictures of the Sharp Memory LCD breakout board I just designed in DipTrace. The learning curve is definitely very short. It’s not always obvious were a certain option or menu item is hiding, but nothing some Googling can’t fix. Overall feel of the tool is that they started with basic functionality and added just enough higher end features to cover the majority of typical design needs. I like it so far.The 3D models are not exact, since I am using what I could find for the parts. Not all vendors are nice enough to provide their models just yet.
