## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TEL0070:1` (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/TEL0070:1.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

*NOTE: This board is currently v3.0 the image is outdated at the time this note was written.*

**Introduction**

 This multiplexer has a set of interfaces for a variety of multi-function adapter plates. It supports USB, TTL, RS232, RS485 interfaces between the system conversions. What's more powerful is that it also supports one input multiple outputs, which greatly facilitates the communication between various controllers. Tip: Multiplexer board is divided into A and B interfaces. The signal can be converted between A and B. The signal in the same interface can't be converted thus only one sender in the same interface, but it allows to have multiple receivers. In this example, USB signal is converted to TTL, RS232 and RS485 at the same time. **Specification**

- Supply Voltage: 3.3V to 5V
- Power LED on board
- Size:52x37mm
