## Pricing

- **Price:** $13.20 (inc GST) — $12.00 AUD, exc GST
- **Quantity discounts:** 10+ $11.64 (exc GST) · 50+ $11.40 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 4 today, and up to 500 more in 7–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA254:1` (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/ADA254:1.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

Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use.

- Onboard 5v->3v regulator provides 150mA for power-hungry cards
- 3v level shifting means you can use this with ease on either 3v or 5v systems
- Uses a proper level shifting chip, not resistors: less problems, and faster read/write access
- Use 3 or 4 digital pins to read and write 2Gb+ of storage!
- Activity LED lights up when the SD card is being read or written
- Four #2 mounting holes
- Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove
- Comes with 0.1" header (unattached) so you can get it on a breadboard or use wires - your choice
- Tested and assembled here at the Adafruit factory
- Works great with Arduino, with tons of example code and wiring diagrams
 
To use with an Arduino, connect **GND** to ground, **5V** to 5V, **CLK** to pin 13, **DO** to pin 12, **DI** to pin 11, and **CS** to pin 10. Then you can use the Arduino IDE's SD library which supports FAT and FAT32 SD cards.
