## Summary

Hosts Carl and Corey discuss the Stackpole JW60-Z-T0300, a 0-ohm through-hole resistor that is literally just a piece of wire, highlighting its absurd marketing and high inventory. They then examine the Atmel SAM-V71 microcontroller, noting its Cortex-M7 core and integrated CAN-FD and USB peripherals, while warning about early silicon lacking ISO CAN-FD compliance. The remainder of the episode is a deep dive into the CAN bus protocol, covering its differential signaling, hardware-level arbitration, bit stuffing, and error handling, before introducing CAN-FD as a solution for higher throughput.
