**Type:** Product page · **SKU:** ADA4351 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/adafruit-infineon-trust-m-breakout-board-stemma-qt-qwiic.html ([markdown](https://core-electronics.com.au/adafruit-infineon-trust-m-breakout-board-stemma-qt-qwiic.html.md))

This is a STEMMA I2C breakout for the Infineon OPTIGA TRUST M SLS 32AIA. OPTIGA Trust M is the next generation of Trust X. OPTIGA Trust M brings RSA 1K/2K + ECC256/384.

## Pricing

- **Price:** $8.80 (inc GST) — $8.00 AUD, exc GST
- **Quantity discounts:** 10+ $7.76 (exc GST) · 50+ $7.60 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 20 and Aug 24.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4351:1` (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/ADA4351:1.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)
- **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt
## Description

This is a STEMMA I2C breakout for the [Infineon OPTIGA TRUST M SLS 32AIA](https://www.infineon.com/cms/en/product/security-smart-card-solutions/optiga-embedded-security-solutions/optiga-trust/optiga-trust-x-sls-32aia/).

OPTIGA Trust M is the next generation of Trust X. OPTIGA Trust M brings RSA 1K/2K + ECC256/384.

A crypto authentication chip much like the [ATECC608 STEMMA](https://core-electronics.com.au/adafruit-atecc608-breakout-board-stemma-qt-qwiic.html) we put into the shop last week, but with: ECC NIST P256/P384, SHA-256, TRNG, DRNG, RSA® 1024/2048 and 4.5K of user memory.

This chip can store your private keys securely, as well as generate true random numbers, which is what we’ve got going on in this demo below. Check out [https://github.com/Infineon/optiga-trust-m for the Arduino library](https://github.com/Infineon/optiga-trust-m)

Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard. Four 2.5mm (0.1") mounting holes for easy attachment. [Clear Padock](https://core-electronics.com.au/large-clear-practice-padlock.html) and [STEMMA QT cable](https://core-electronics.com.au/jst-sh-4-pin-to-premium-male-headers-cable-qwiic-compatible-150mm-long.html) not included.**
