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/WS-17912:1.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 2-Channel Isolated CAN Bus Expansion HAT for Raspberry Pi, MCP2515 + SN65HVD230 Dual Chips Solution, Multi Onboard Protection Circuits **What can it do?** Enable isolated and stable CAN bus capability for your Raspberry Pi ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-3_960_30022a4f494.jpg) Designed for the Raspberry Pi series Standard Raspberry Pi 40PIN GPIO header, customized for Raspberry Pi series boards ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-5_960_3258117053b.jpg) ### Features - Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication - Integrated power isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal - Onboard digital isolator, signal isolation makes the communication more safe, more stable, and better anti-interference - Onboard TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient peak voltage protection - Onboard voltage translator, select 3.3V/5V operating voltage by jumper - Onboard 120O terminal resistor, configured by jumper - Breakout SPI control pins, for connecting with host control boards like STM32/Arduino 2-Channel CAN capability MCP2515 CAN controller + SN65HVD230 CAN transceiver ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-7_960_2931023dbd2.jpg) Electrical isolation circuitry safe & stable SM24CANB TVS diode, ESD protection, transient peak voltage protection ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-9_960_24183a169f1.jpg) Flexible and handy jumpers easily select 3.3V / 5V operating voltage, or enable/disable 120O terminal resistor, via onboard jumpers ### ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-11_960_28978a1e2e1.jpg) What's On Board ![](https://core-electronics.com.au/attachments/localcontent/2-CH-CAN-HAT-13_960_27321c35949.jpg) 1.
