## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5394:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5394:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This lovely little display breakout is the best way to add a small, colorful, and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.9" display has 320x170 16-bit full-color pixels and is an **IPS** display, so the color looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and Adafruit's Arduino library supports it well.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator, auto-reset circuitry, and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. They also had a little extra space, so they placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, [but you can pick one up here](https://core-electronics.com.au/sd-microsd-memory-card-4-gb-sdhc.html).

Of course, Adafruit wouldn't just leave you with a datasheet and a "good luck!" - [Adafruit have written a full open-source graphics library that can draw pixels, lines, rectangles, circles, text, and bitmaps as well as example code](https://github.com/adafruit/Adafruit_ILI9341). The code is written for Arduino but can be easily ported to your favorite microcontroller! Wiring is easy, Adafruit strongly encourage using the hardware SPI pins of your Arduino as software SPI is noticeably slower when dealing with this size display.

This display breakout also features an 18-pin "EYE SPI" standard FPC connector with flip-top connector. You can use an 18-pin 0.5mm pitch FPC cable to connect to all the GPIO pins, for when you want to skip the soldering.

**Please note!** This display is designed original for smartwatches and similar, where there's a glass over the screen. Without something gently holding the screen down, the backlight can eventually peel away from the TFT. (It's not destructive but it's unattractive) You can prevent this by, ideally, adding a plastic or glass cover/overlay. If using bare, try dabbing a touch of E6000 or similar craft glue on the thin side edges, or using a thin piece of tape to keep the front TFT attached to the backlight.
