- **Quantity discounts:** 10+ $1.72 (exc GST) · 50+ $1.68 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1935:1` (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/ADA1935:1.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

That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your [FONA](https://core-electronics.com.au/adafruit-fona-mini-cellular-gsm-breakout-ufl-version-v1.html).

This microphone's very similar to Adafruit's [PCB-mount Elecret Microphone](https://core-electronics.com.au/electret-microphone-20hz-20khz-omidirectional.html) but is significantly smaller and has pre-attached 65mm long wires. Adafruit don't have a specific datasheet for it but it can be biased with 2V and 2K impedence. You do need an electret microphone amplifier to boost the millivolt-signal up to line level. The FONA has this amplifier part built into it but something like an Arduino does not.

Adafruit tested it with the FONA and it works great for voice purposes, you may also be able to use it with Adafruit's other microphone amplifiers (like [\#1713](https://core-electronics.com.au/electret-microphone-amplifier-max9814-with-auto-gain-control.html) and #[1063](https://core-electronics.com.au/electret-microphone-amplifier-max4466-with-adjustable-gain.html)) and if you desolder the onboard microphones.

## Technical Details
