## Pricing

- **Price:** $21.55 (inc GST) — $19.59 AUD, exc GST
- **Quantity discounts:** 10+ $18.81 (exc GST) · 25+ $18.22 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 21 and Sep 01.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10059:1` (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/CE10059:1.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

The M5Stack DAC2 Hat is a precision digital-to-analog conversion unit engineered for seamless integration with StickC series controllers. Featuring the GP8413 solution, this sophisticated device delivers exceptional 15-bit resolution across dual independent 0-10V analog outputs with remarkable accuracy - achieving a mere 0.2% output voltage error and 0.01% linearity.

### Key Features

- Dual-channel 15-bit digital-to-analog conversion
- Selectable 0-5V or 0-10V output ranges
- Ultra-precise output with just 0.2% voltage error
- Superior 0.01% linearity performance
- I2C communication with default address 0x59
- 3-bit hardware addressing enables parallel connection of up to 8 devices
- Built-in output short-circuit protection
- Operating temperature range: 0-40°C

### How to Use

The DAC2 Hat connects directly to M5Stack StickC series controllers including the [M5Stack Core2 ESP32 IoT Development Kit](https://core-electronics.com.au/m5stack-core2-esp32-iot-development-kit-48597.html) through the built-in HAT interface. Configuration is handled via I2C communication, with the default address set to 0x59. Multiple DAC2 Hats can be connected in parallel by configuring unique addresses through the 3-bit hardware addressing system.

For protection during operation, the integrated short-circuit protection automatically shuts down outputs if a connection to ground is detected, preventing damage to the device and connected equipment.

### Applications

- Precision motor speed control systems
- LED brightness regulation
