## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07510:1` (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/CE07510:1.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 Bi-Directional Logic Level Converter is a breadboard-friendly device that converts between eg. 5V and 3.3V logic. The four channels are independent and work in both directions, making this converter appropriate for shifting I2C bus voltages.

Power the board from the two voltage sources you're using. Connect the higher voltage (eg. 5V) to the 'HV' power pin, the lower voltage (eg. 3.3V) to the 'LV' power pin, and the ground to the 'GND' pin.

**Features:**

- 4 independent channels
- Breadboard friendly - just bring your own [pin headers](https://core-electronics.com.au/10-pcs-40-pin-headers-straight.html)
- Small size (15x13mm)
- Manufactured and [supported](https://core-electronics.com.au/contacts/) in Australia by Core Electronics
