# M5Stack Mini Heart Rate Unit Pulse Oximeter (MAX30100)

**Type:** Product page · **SKU:** CE07670 · **Brand:** [M5Stack](https://core-electronics.com.au/brands/m5stack-australia)
**Page:** https://core-electronics.com.au/m5stack-mini-heart-rate-unit-pulse-oximeter-max30100.html ([markdown](https://core-electronics.com.au/m5stack-mini-heart-rate-unit-pulse-oximeter-max30100.html.md))

HEART is built using the MAX30100 chipset. MAX30100 is a complete pulse oximetry and heart-rate sensor system solution designed for the demanding requirements of wearable devices. The MAX30100 provides very small total solution size without sacrificing optical or electrical performance. Minimal external hardware components are needed for integration into a wearable device.

> ⚠ Deal is for shelf stock only — any additional stock will be at the normal price.

## Pricing

- **Price:** $16.41 (inc GST) — $14.92 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 6 today; more stock is typically available with a 8–19 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07670:1` (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/CE07670:1.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)
