## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DEV-20812:1` (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/DEV-20812:1.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 PureThermal 3 FLIR Lepton Smart I/O Module is a hackable thermal webcam module for the FLIR Lepton Longwave Infrared (LWIR) camera core. It ships preconfigured to operate as a plug-and-play UVC 1.0 USB thermal webcam that will work with standard webcam apps such as VLC Media Player on PC, Linux, Mac, and Android. For developers, its reference firmware, viewer software, and hardware schematic are all open source!

Each PureThermal 3 is equipped with the reliable STM32F412 ARM microprocessor capable of processing images without any external system inputs. With a Lepton inserted into the PureThermal 3 you will be able to achieve 9Hz color video over USB using the USB UVC class. If USB isn't necessarily your desired medium, this board has also been fitted with 0.1" pins to interface over UART or I2C.

**Note:** The PureThermal 3 does **NOT** include a FLIR Lepton imaging module and will need to be purchased separately or in the [Combo Board](https://core-electronics.com.au/search/?q=20813). The Lepton module is extremely sensitive to electrostatic discharge (ESD). When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module.
