## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=BOB-19389:1` (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/BOB-19389:1.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 SparkFun Analog MEMS Microphone Breakout makes it easy to work with the SPH8878LR5H-1 analog microphone from Knowles. This board features an OpAmp to bring the output of the microphone to a usable level, allowing you to plug directly into an ADC on a microcontroller or something like the [SparkFun Spectrum Shield](https://core-electronics.com.au/spectrum-shield-11897.html).

In addition to amplifying the signal, the OpAmp adds a bias voltage of 1/2 VCC. With sound sources such as a normal speaking voice a few feet away from the microphone, the AUD output signal will be at about 200mV peak-to-peak. Also note, this low profile microphone has its port on the bottom side, so the microphone can be mounted flush to the outer surface of your enclosure. This microphone is omni-directional, which means it does a good job of picking up sound sources from all directions.
