# M5StickS3 ESP32-S3 Mini IoT Development Kit

**Type:** Product page · **SKU:** CE11197 · **Brand:** [M5Stack](https://core-electronics.com.au/brands/m5stack-australia)
**Page:** https://core-electronics.com.au/m5sticks3-esp32-s3-mini-iot-development-kit.html ([markdown](https://core-electronics.com.au/m5sticks3-esp32-s3-mini-iot-development-kit.html.md))

Turn an idea into a working, battery-powered wireless gadget without a breadboard or a single extra part.

## Pricing

- **Price:** $44.07 (inc GST) — $40.06 AUD, exc GST

## Availability & dispatch

- Available with a lead time — expect dispatch between Nov 09 and Nov 20.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE11197:1` (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/CE11197:1.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

An ESP32-S3 controller with built-in audio, a colour screen and two-way infrared, all in a 48 x 24mm stick. Use it as a voice assistant front end, an infrared remote for smart-home devices, or a portable Wi-Fi IoT node that runs on its own battery.

On most small boards, audio is something you wire in later. On the M5StickS3, sound capture and playback are already built in, and M5Stack's Xiaozhi voice assistant and ESP-Claw guides get it listening and talking before you write any driver code.

If you're upgrading from an M5StickC, check your Hats first. The StickS3 uses the new Hat2-Bus and does not physically fit the Hat Mini JoyC (U156), Hat Mini EncoderC (U157) or Hat 18650C (U080).

External 5V output is off by default in M5Unified; call `M5.Power.setExtOutput(true);` to power Grove devices and the IR transmitter and receiver. When 5V output is on, supply power only through USB or 5VIN on the Hat2-Bus. Turn the speaker amp off while receiving IR, keep volume below 75% on battery power, and don't open the enclosure, because that can damage the antenna.

### Features

- **Build voice-driven projects without extra audio hardware.** A codec, microphone and amplified speaker are built in and already wired.
- **Run larger applications** on a dual-core ESP32-S3 with onboard PSRAM.
- **Control smart-home devices by infrared** with a built-in transmitter and receiver.
- **Add motion input and on-device feedback** with a 6-axis IMU, two programmable buttons and a colour screen.
- **Go untethered** on the built-in battery. Dedicated power management keeps the draw near zero when the device is off.
- **Expand without soldering** through the Hat2-Bus header and the Grove port.
- **Mount it on ferrous metal surfaces** using the magnetic back.
- **Code in the toolchain you already use.** Arduino, UiFlow2, ESP-IDF or PlatformIO, with the M5Unified, M5GFX and M5PM1 libraries.
