Raspberry Pi Pico board

Interesting new micro-controller board and custom chip from Raspberry Pi: Raspberry Pi Pico.

Pico provides a single push button, which can be used to enter USB mass-storage mode at boot time and also as a general input, and a single LED. It exposes 26 of the 30 GPIO pins on RP2040, including three of the four analogue inputs, to 0.1”-pitch pads; you can solder headers to these pads or take advantage of their castellated edges to solder Pico directly to a carrier board.

It is programmable with Python and C/C++. Cross-platform toolchain for development on Windows, macOS, and Linux — including, naturally, the Raspberry Pi family itself Supports TensorFlow Lite.

Raspberry Pi is looking to do for the microcontroller market what they’ve already done for single-board computers with the launch of the Pico. The board — priced at just $4 — is based on the RP2040, a dual-core Cortex-M0+ processor designed in house. It designed to be easy to taken into use.

Announcement at Facebook says:

It’s been a big week. We launched something tiny, something new – Raspberry Pi Pico, just for you.

Read all about it, plus everything else that went down at Raspberry Pi in the last few days, in Raspberry Pi Weekly.

    Raspberry Pi Produced 10 Million RP2040s in 2021, More Pi Stores Likely
    By Les Pounder published 2 days ago
    There’s almost an “infinite” supply of RP2040 chips
    https://www.tomshardware.com/news/raspberry-pi-10-million-rp2040s

    500 Wafers Equals 10 Million RP2040s
    Tom’s Hardware Editor-in-Chief and The Pi Cast co-host Avram Piltch asked Upton “Why are there no shortage of RP2040 based products?” and Upton’s answer “We took some big risks” lead to the revelation that Raspberry Pi purchased 500 wafers in 2021.

    The offer and subsequent decision to purchase 500 wafers came through within a day, Upton said. Per wafer there can be between 21,000 and 22,000 RP2040 die with a die size of roughly 2mm square. Upton then compares the “big chip world” where dies are 30 mm square. The original BCM2835 SoC (as used in the original Raspberry Pi and Raspberry Pi Zero) is based on this tech.

    From a wafer, the yield is approximately 2000 die for 30mm. Newer chips, such as those in the Raspberry Pi Zero 2 W and Raspberry Pi 4 use a 45mm square die, respectively the BCM2710 and BCM2711 packages. From a wafer Raspberry Pi expect to make 1400 die.

    Upton then does the math and from 500 wafers, each yielding around 21,000 die, there are around 10 million RP2040 chips.

    This “stockpile” of chips from 2021 are what many of us keen Pico users are currently consuming, be it in the form of Raspberry Pi Pico , Pico W or third-party boards. Upton then talks about what is “effectively an infinite supply [of RP2040]” based upon how many die can be created per wafer. This is a refreshing statement, given how global supply chains have been hit by the pandemic.

    Upton is keen to steer enthusiasts to the Raspberry Pi Pico / RP2040 and backs this up by stating that he wants the Pico to be a product that never runs out and says that he has gone as far as to strategically purchase “millions of units” of the many other components that make up the board (buck / boost converter, Wi-Fi etc). These bulk purchases mean that it is virtually impossible for the Raspberry Pi Pico to go out of stock.

    Altmode Friend Easily Adds USB-C PD to Any Project
    RP2040-powered building block for managing Power Delivery.
    https://www.hackster.io/news/altmode-friend-easily-adds-usb-c-pd-to-any-project-655476db4a5d

    For end users, the USB’s Power Delivery (PD) specification means a single power supply can efficiently power small or large devices. This flexibility is because the spec enables a power supply (source) and device (sink) to communicate their capabilities and requirements to negotiate the best option for delivering power. Unfortunately, incorporating PD into a project is more complex than a couple of resistors, like with previous generations of USB. Thankfully, drop-in modules like the Altmode Friend add USB PD to any project.

    A Disposable Dumper For ROM Chips With A Pi Pico
    https://hackaday.com/2023/02/02/a-disposable-dumper-for-rom-chips-with-a-pi-pico/

    ROM dumping is vital for preserving old hardware, and we’ve seen many hacks dedicated to letting someone dump a ROM and send its contents to some hacker stuck with a piece of technology that lost its firmware. However, that requires ROM dumping tools of some kind, and it’s often that the lucky ROM-equipped hacker doesn’t own such tools. Now, you could mail the chip to someone else, but postal services in many countries are known to be UDP-like — lossy and without delivery guarantees. The risk of leaving both hackers without a ROM chip is quite real, so, instead of mailing ROM chips or expensive devices around, [Amen] proposes a cheap and disposable flash dumping tool that you could mail instead.

    Simple MP3 Audio Playback With Raspberry Pi Pico
    https://embeddedcomputing.com/technology/processing/interface-io/simple-mp3-audio-playback-with-raspberry-pi-pico

    The RP2040, with a processing speed of 133 MHz, is capable of decoding MP3 files, and the Pico RP2040 dev board includes 2 MB of Flash–enough to store a significant amount of compressed audio. At a list price of $4, the Pico therefore makes an incredible and cost-effective platform for embedded audio playback.
