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.

## Pricing

- **Price:** $30.15 (inc GST) — $27.41 AUD, exc GST
- **Quantity discounts:** 10+ $26.31 (exc GST) · 25+ $25.49 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Sep 01 and Sep 14.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE07671:1` (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/CE07671:1.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

YUN HAT is a cloud-shaped multi-function environment information measurement base. Built-in temperature and humidity sensor SHT20, air pressure sensor BMP280, photoresistor,14 RGB LEDs. The board is built with Embedded Microprocessor \* STM32F030F4\*\* , which implemented concise and efficient program APIs.

YUN HAT features a pretty appearance that could be used as a decoration for your space.

The base is designed for the M5StickC, like other HAT devices, it is compatible with top socket of M5StickC. The overall structure adopts a three-layer design, and the upper and lower PCB boards serve as fixed structure and main circuit respectively, which is beneficial to the circuit conduct long hours of work.
the board also provides an independent external power interface.

The middle layer is a light-guided acrylic component. To achieve a better light display effect, The acrylic outer contour cutting surface is partially polished, and the purpose is to effectively reduce the scattering of light, making it evenly saturated with light effects.

One hook hole and two 64mm magnet mounting positions are reserved on the board, so users can easily magnet or hang in any corner of space.
