It’s blue! It’s thin! It’s the Pro Mini! This is a 5V board running the 16MHz bootloader. Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need

## Pricing

- **Price:** $4.30 (inc GST) — $3.91 AUD, exc GST
- **Quantity discounts:** 10+ $3.52 (exc GST) · 50+ $3.33 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 16 today; more stock is typically available with a 8–12 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=018-MINI-05:1` (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/018-MINI-05:1.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

It’s blue! It’s thin! It’s the Pro Mini! This is a 5V board running the 16MHz bootloader. Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time users start with the [Arduino® Uno R3](https://core-electronics.com.au/arduino-uno-r3.html). It’s a great board that will get you up and running quickly. The Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off-board.

Pro Mini is made with all SMD components on two layers of PCB. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. There is a voltage regulator on board so it can accept voltage up to 9VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin and not VCC.

## Dimensions:

- 0.7x1.3" (18x33mm)
 
## Features:

- **This board is a generic variant**, built from the open-source design. It is a compatible replacement for the official Arduino® Pro Mini, however, we recommend and guarantee that only the official variant will work with all Arduino® educational resources wherever it is referenced. Buying official also supports the creators and their future innovations.
