    Speed Boost Update for Raspberry Pi Pico Boards

    Key Takeaways

    1. Raspberry Pi has upgraded its RP2040 microcontroller speed to 200 MHz, a 50% increase from the original 133 MHz.
    2. The new speed option is available with version 2.1.1 of the Pico SDK, but may cause compatibility issues with existing programs.
    3. The higher speed requires a voltage increase to 1.15 V, compared to the previous 1.10 V.
    4. The 200 MHz mode is not enabled by default and must be activated by setting SYS_CLK_MHZ=200 in the code.
    5. A similar speed upgrade may be possible for the RP2350, which currently operates at a maximum of 150 MHz.

    Raspberry Pi has quietly introduced a significant speed upgrade to its RP2040 microcontroller, which is used in single-board computers (SBCs) like the Pico W (currently priced at $15.99 on Amazon). The RP2040, which made its debut in early 2021, features Cortex-M0+ cores and was known for its relatively low cost. Originally, these cores operated at speeds of up to 133 MHz, or 125 MHz at a voltage of 1.10 V.

    New Speed Options

    With the release of version 2.1.1 of the Pico SDK, there is now an option to run at 200 MHz, marking a 50% increase over the standard speeds. However, this enhancement comes with some drawbacks. Raspberry Pi has cautioned users that this new speed may lead to compatibility issues with some existing programs. Additionally, the new 200 MHz mode requires a higher voltage, with 1.15 V specified in the release notes for v2.1.1.

    Activation Process

    Due to these considerations, the new CPU mode at 200 MHz is not enabled by default in v2.1.1. To activate it, users simply need to set SYS_CLK_MHZ=200 using a preprocessor define. Raspberry Pi has also suggested that a similar upgrade might be possible for the RP2350, which is currently limited to a maximum of 150 MHz.

  • Leica M2 Upgraded to Digital with Raspberry Pi and 64 MP Sensor

    Leica M2 Upgraded to Digital with Raspberry Pi and 64 MP Sensor

    The initial version of the Leica MPi was introduced by Michael Suguitan as an open-source initiative in May 2023. Since then, there have been several important enhancements to the project. The core concept stays unchanged: the Leica M2 is paired with a Raspberry Pi and a camera sensor that works together to turn the classic 1957 rangefinder camera into a modern digital device.

    Improved Sensor Features

    In the latest iteration, the previous 12 MP Sony IMX477 sensor in a 1/2.3 inch format is substituted with a larger Arducam OwlSight sensor, boasting 64 MP in a 1/1.32 inch size. This upgraded sensor provides a magnification factor of 3.7, transforming the Laowa 9 mm f/5.6 lens into a lens that behaves like a 33 mm on a full-frame camera, while a 90 mm lens becomes equivalent to a 333 mm telephoto lens. Additionally, the new sensor allows for taking vibrant color photos during daytime, a feature that was hindered in the earlier model because there was no infrared filter, leading to color distortions.

    New Features and Design

    Changes also include support for flash and a built-in battery charged via USB-C. As illustrated in the video below, the digital module adds noticeable thickness to the middle section of the Leica M2, which restricts the viewfinder usage to the right eye only. For those interested in recreating this project on their own, the price of the camera should be taken into account, as finding a used Leica M2 now typically costs over $2,220.

    How to Get Involved

    The Leica MPi is available as an open-source project on Github, so if you’re looking to modify a Leica M2, you will need to do it yourself. The most cost-intensive parts necessary for assembly include the Arducam OwlSight camera sensor, priced around $60, the Raspberry Pi Zero 2 at $21, and the Waveshare LCD, which is about $14. If you wish to support the creator of this project, Michael Suguitan, you can purchase a photography book in A5 size that contains at least 30 pages for $20, plus shipping and import taxes, through Kickstarter.
