## Pricing

- **Price:** $19.05 (inc GST) — $17.32 AUD, exc GST
- **Quantity discounts:** 10+ $16.80 (exc GST) · 50+ $16.45 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 24 and Aug 31.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4077:1` (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/ADA4077:1.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

If you have a custom PCB design and you'd like to add a little Bluetooth Low Energy, this module is ultra compact and easy to use. It contains a Nordic **nRF52832** chip that comes integrated with BLE radio as well as most of the supporting circuitry and even a chip antenna. The whole thing comes with FCC, CE and TELEC certifications.

**Please note!** **The module comes with a *blank* chip** - this is for people who are comfortable programming the chips themselves with a J-Link programmer and the Nordic SDK. We **don't** provide any firmware to go along with it!

This is the same module Adafruit use for the [Adafruit nRF52832 Feather](https://core-electronics.com.au/adafruit-feather-nrf52-bluefruit-le-nrf52832.html) so [if you'd like to see a possible reference design for this module, check out the PCB files here!](https://github.com/adafruit/Adafruit-nRF52-Bluefruit-Feather-PCB)

Of course the best way to program these chips is with the Nordic SDK. This chip also has [some basic Arduino support](https://github.com/sandeepmistry/arduino-nRF5), [some micropython support](https://github.com/micropython/micropython/tree/master/ports/nrf), and is [well supported by MyNewt](https://mynewt.apache.org/latest/tutorials/blinky/nRF52.html). Either way you go (SDK/micropython/Arduino) you'll still need to solder this onto a PCB and load code via a SWD programmer.
