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/ADA3263:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time Adafruit have [suggested Adafruit's MAX31855K breakout, which works great but is only for K-type thermocouples](https://core-electronics.com.au/thermocouple-amplifier-max31855-breakout-board-max6675-upgrade-v2-0.html). Now Adafruit are happy to offer a great new thermocouple amplifier/converter that can handle just about *any* type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any **K**, **J**, **N**, **R**, **S**, **T**, **E**, or **B** type thermocouple. This breakout does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). Adafruit even added inline resistors and a filter capacitor on-board for better stability, as recommended by Maxim. [Goes great with Adafruit's 1m K-type thermocouple](https://core-electronics.com.au/thermocouple-type-k-glass-braid-insulated-k.html) or any other thermocouple, really! - Works with any **K**, **J**, **N**, **R**, **S**, **T**, **E**, or **B** type thermocouple - **-210°C to +1800°C output in 0.0078125° resolution** - note that many thermocouples have about ±2°C to ±6°C accuracy or worse depending on the temperature and type, so the resolution will be a lot better than the accuracy! - Internal temperature reading - 3.3 to 5v power supply and logic level compliant! - SPI data requires any 4 digital I/O pins **Please note: this does not include a thermocouple!** [Check out Adafruit's tutorial for wiring diagrams, files, software and more!](https://learn.adafruit.com/adafruit-max31856-thermocouple-amplifier) ## Technical Details [EagleCAD PCB files, datasheets, Fritzing object and more in the tutorial!](https://learn.adafruit.com/adafruit-max31856-thermocouple-amplifier/downloads) Product Dimensions: 25.0mm x 22.0mm x 3.0mm / 1.0" x 0.9" x 0.1" Product Weight: 3.5g / 0.1oz ![](https://core-electronics.com.au/attachments/localcontent/rohs_icon_8216055e11.jpg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/3/2/3263-00.jpg)
