    The RP2350 with the Raspberry Pi Team

    James Adams, Chris Boross, Liam Fraser, and Luke Wren from the Raspberry Pi team discuss the RP2350 microcontroller, detailing its evolution from the RP2040 with a focus on new security features, low-power modes, and the addition of a RISC-V core (Hazard 3). The team explains the architectural challenges of integrating dual cores, the enhanced Programmable I/O (PIO) subsystem, and the implementation of secure boot with hardware countermeasures against fault injection. They also share insights from a recent security challenge, revealing exploits like passive voltage contrast on OTP memory, and discuss the future of the RP2040 and upcoming Pico 2 variants.

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

    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.

    New Year, New Gear

    Hosts Chris Gammell and Dave Jones review new test equipment, including a Siglent active load and a Thermaltronics soldering iron, discussing their technical specs and utility. They then analyze the Raspberry Pi Pico and its RP2040 microcontroller, debating its classification as a microcontroller versus a microprocessor due to its lack of internal flash. Finally, they discuss Seeed Studio's StarFive RISC-V board and the broader implications of open-source instruction sets in the semiconductor industry.

    Ep 221: The Future of the Raspberry Pi, Sniffing a Toothbrush, Your Tactical Tool Threshold

    Editors Elliot Williams and Tom Nardi discuss the future of single-board computers, noting that the Raspberry Pi Foundation's educational goals may be met as mini-PCs become cheaper, while the RP2040-based Pico handles simpler tasks. They review the Beat Barry, a handheld Linux device built around a Raspberry Pi Zero and a repurposed Blackberry keyboard, and a tiny 3D-printed robot using an ESP32. The hosts also cover reverse-engineering a Philips Sonicare toothbrush's NFC chip, the rise of electric and autonomous farm equipment, and a DIY tipping-bucket rain gauge.

    The RP1 and beyond with the Raspberry Pi Hardware team

    James Adams (CTO) and Liam Fraser (Hardware/Software Engineer) from Raspberry Pi discuss the development of the RP1 custom silicon, the success of the RP2040 microcontroller, and the architecture of the Raspberry Pi 5. They explain how RP1 acts as a Southbridge/chiplet to offload I/O functions from the main Broadcom SoC, allowing for cost and complexity reductions as process nodes shrink. The conversation covers their internal chip design tooling, sourcing strategies during the chip shortage, and the rationale for sticking with ARM over RISC-V.
