- We can dispatch 1 today; more stock is typically available with a 10–14 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TSX00005:1` (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/TSX00005:1.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)

### OSH: Schematics

MKR2UNO is open-source hardware! You can build your own board using the following files:

- [Eagle Files](https://core-electronics.com.au/attachments/localcontent/MKR2UNO-reference_48933e3c1f9.zip)
- [Schematics](https://core-electronics.com.au/attachments/localcontent/MKR2UNO-schematic_19453c6ee23.pdf)
 
Please keep in mind that the MKR2UNO is just a form factor adapter and so is NOT present any voltage translation. Be careful before connecting a shield since shield without IOREF level shifting capability may not work properly.

Like in many others Arduino boards this adapter allows to power your MKR board using a barrel jack with center positive polarity or the VIN pin on the headers.

If you want to use the Arduino MKRZero and the Arduino WIFi shield 101 read the Arduino WIFi shield 101 reference to change module pins.

Unlike the Arduino UNO, the MKR2UNO Adapter do NOT have I2C signals on A4 and A5 and SPI on pins 11, 12 and 13.

All the pins on the MKR2UNO Adapter are wired one to one from the MKR to the UNO form factor with some exception:

 | **MKR form factor pin** | **UNO form factor pin** |
|---|---|
| 0 | 13 |
| 1 | 10 |
| 13 | 0 |
| 14 | 1 |
