# M5Stack RS485 to TTL Converter Unit

**Type:** Product page · **SKU:** CE07681 · **Brand:** [M5Stack](https://core-electronics.com.au/brands/m5stack-australia)
**Page:** https://core-electronics.com.au/m5stack-rs485-to-ttl-converter-unit.html ([markdown](https://core-electronics.com.au/m5stack-rs485-to-ttl-converter-unit.html.md))

It's used to convert the TTL standard to the RS485 standard. If the outside serial device is RS485 standard, you can attach this unit onto M5stack, therefore, to implement the communication with RS485 device by TTL protocol.

## Pricing

- **Price:** $11.25 (inc GST) — $10.23 AUD, exc GST
- **Quantity discounts:** 10+ $9.82 (exc GST) · 25+ $9.51 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 18 and Aug 31.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07681:1` (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/CE07681:1.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

RS485 is a TTL to RS485 convertor.

RS485 is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems, widely used in industrial field. multipoint systems are supported.

It's used to convert the TTL standard to the RS485 standard. If the outside serial device is RS485 standard, you can attach this unit onto M5stack, therefore, to implement the communication with RS485 device by TTL protocol.
