Arduino Announces Board Based On Raspberry Silicon

February 16, 2021 by 62 Comments

The Raspberry Pi Pico burst onto the microcontroller scene last month with much fanfare, and is already popping up in projects left, right and center. Notable for its high clock speed and exciting IO features, it’s a breath of fresh air in a market slowly weaning itself onto ARM architectures and away from 8-bit staples. Not one to miss out on a slice of the action, Arduino have announced their own upcoming board based on the Pico’s RP2040 chip.

The board is named the Arduino Nano RP2040 Connect, a moniker that’s not just a mouthful but likely to be confused with existing Arduino Nano products. It sports several differences to the Raspberry Pi Pico, namely packing WiFi, Bluetooth, and an IMU on board which should make developing motion-sensitive and IoT projects easier, particularly in cases where the Pico’s flexible IO could be useful.

Naturally, Arduino IDE integration will be a major plus point that gets many makers on board, and we can imagine there will be swift development of libraries leveraging the RP2040’s PIO subsystem. If you still haven’t gotten the low down on the Raspberry Pi Pico yet, though, never fear – our own [Elliot Williams] can tell you everything you need to know!

Arducam Now Working With The RPi Pico

February 2, 2021 by 29 Comments

The Raspberry Pi Pico came out of absolutely nowhere, and has taken the maker world by storm. At the low, low cost of $4, packing some seriously grunty original silicon, and even available free on the cover of magazines, it’s already got a legion of fans. As with any new popular platform, there’s a scramble to get everything under the sun running on the hardware. Already, ArduCAM is up and running on the Raspberry Pi Pico!

Based on the OV2640 image sensor, the ArduCAM is useful for microcontroller applications thanks to its onboard JPEG encoder. This limits the amount of RAM needed onboard the microcontroller to deal with the images fed from the camera. With the Pico now on the market, the team behind ArduCAM set about writing a library to get everything playing nicely with the SPI camera. It’s available on Github, complete with an example program so you can check everything is functional right out of the box. The easiest way to get up and running is from a Raspberry Pi environment, but the Pico acts as a USB Mass Storage device so can be programmed from virtually anywhere.

We’ll likely see the whole cavalcade of microcontroller bits and pieces ported to the Pico in the coming months, along with plenty of interesting uses of the special IO features. Video after the break.

A Look At The Interesting RP2040 Peripheral, Those PIOs

January 29, 2021 by 41 Comments

The Raspberry Pi Pico is the latest product in the Raspberry Pi range, and it marks a departure from their previous small Linux-capable boards. The little microcontroller board will surely do well in the Pi Foundation’s core markets, but its RP2040 chip must have something special as a commercial component to avoid being simply another take on an ARM microcontroller that happens to be a bit more expensive and from an unproven manufacturer in the world of chips. Perhaps that special something comes in its on-board Programable IO perhipherals, or PIOs. [CNX Software] have taken an in-depth look at them, which makes for interesting reading.

Raspberry Pi Enters Microcontroller Game With $4 Pico

January 20, 2021 by 351 Comments

Raspberry Pi was synonymous with single-board Linux computers. No longer. The $4 Raspberry Pi Pico board is their attempt to break into the crowded microcontroller module market.

The microcontroller in question, the RP2040, is also Raspberry Pi’s first foray into custom silicon, and it’s got a dual-core Cortex M0+ with luxurious amounts of SRAM and some very interesting custom I/O peripheral hardware that will likely mean that you never have to bit-bang again. But a bare microcontroller is no fun without a dev board, and the Raspberry Pi Pico adds 2 MB of flash, USB connectivity, and nice power management.

As with the Raspberry Pi Linux machines, the emphasis is on getting you up and running quickly, and there is copious documentation: from “Getting Started” type guides for both the C/C++ and MicroPython SDKs with code examples, to serious datasheets for the Pico and the RP2040 itself, to hardware design notes and KiCAD breakout boards, and even the contents of the on-board Boot ROM. The Pico seems designed to make a friendly introduction to microcontrollers using MicroPython, but there’s enough guidance available for you to go as deep down the rabbit hole as you’d like.

Our quick take: the RP2040 is a very well thought-out microcontroller, with myriad nice design touches throughout, enough power to get most jobs done, and an innovative and very hacker-friendly software-defined hardware I/O peripheral. It’s backed by good documentation and many working examples, and at the end of the day it runs a pair of familiar ARM MO+ CPU cores. If this hits the shelves at the proposed $4 price, we can see it becoming the go-to board for many projects that don’t require wireless connectivity.

But you want more detail, right? Read on.
