Ep102: Raspberry Pi Microcontroller, Microphone Killswitch, and a 45-Degree 3D-Printer

Hackaday Podcast · 22 Jan 2021 · 53m · Episode 102

What this episode covers

Hackaday editors Elliot Williams and Mike Szczys review the Raspberry Pi Pico microcontroller, highlighting its RP2040 chip, dual Cortex-M0+ cores, and unique Programmable IO (PIO) hardware for precise bit-banging. They also discuss an Amazon Echo Flex teardown revealing a hardware-based microphone killswitch, and a 45-degree 3D printer that eliminates the need for support structures by angling the nozzle. The episode covers various community hacks, including a wall-sized pen plotter, an open-source RC protocol, and a Dubai LED bulb design focused on longevity.

Embedded Hardware with the Raspberry Pi Team
James Adams, Liam Fraser, and Luke Renn from Raspberry Pi Trading discuss the development of the RP2040 microcontroller and the Pico board. They explain the architectural decisions behind the chip, including the use of programmable IO (PIO) state machines, the choice of Cortex-M0+ cores, and the strategic decision to use external flash to maximize SRAM and minimize cost. The conversation also covers the company's flat engineering culture, their low-cost manufacturing strategy, and the integration of the Compute Module 4 (CM4) into industrial applications.
