## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0647:1` (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/DFR0647:1.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 OLED display module uses the SSD1306 drive chip, has 128x32 self-illuminating white pixels, and adopts the back chip-mounting pad design. Small size, the length is 41mm and the width is only 12mm. With its small size, simple wiring, and low power consumption, it can be applied to many display applications, such as wearable display devices, Mini small game consoles, desktop widgets, etc.

The display module adopts a high-contrast, low-power OLED display. Full-screen lighting consumes approximately 25mA (3.3V) 25mA (5V) and full-screen off power consumption: approx. 2mA (3.3V) 2mA (5V). It is compatible with controllers such as [Arduino UNO](https://www.dfrobot.com/category-104.html), Leonardo, [ESP32/ESP8266](https://www.dfrobot.com/category-271.html), FireBettle-M0, and so on. Internal power-on reset processing, I2C communication methods and the chip-mounting pad, so that your welding line will be more convenient and simpler. The [module ](https://www.dfrobot.com/category-156.html)has an ultra-narrow PCB design that is more flexible to match more applications.

**Note:** Turn the pixels off when you are not using the display to prevent the use of some pixels too long to darken them, which will cause the brightness uniformity problem.
