## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0316:1` (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/DFR0316:1.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 module integrates MCP3432 A/D converter chip. The module can provide analog input function for Raspberry Pi and provide high accuracy analog input for Arduino.

MCP3424 is one of the low noise and high accuracy 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter family members of the MCP342X series. Its characteristic is:
Self calibration of internal offset and gain per each conversion.

User can select the PGA gain before the analog-to-digital conversion takes place. This allows the device to convert a very weak input signal with high resolution.

The device have two conversion modes:

- (a)One-Shot mode: the device performs a single conversion and enters a low current standby mode automatically until it receives another conversion command.
- (b)Continuous mode: the conversion takes place continuously at the set conversion speed.
