Raspberry Pi has entered the microcontroller market with the $4 Raspberry Pi Pico, a brand-new piece of {hardware} primarily based on the corporate's personal customized silicon.

The Raspberry Pi Pico is the primary microcontroller board from the British board maker and has been constructed across the new RP2040 chip.

Whereas conventional Pi boards must be paired with a microcontroller so as to management a bodily gadget – say, a robotic or a climate balloon – the Pico bridges this hole between {hardware} and software program by offering a direct analogue connection to the top gadget.

James Adams, Raspberry Pi COO and {hardware} lead, provided a extra technically compelling rationalization of how the expertise works. "Raspberry Pi by itself doesn't assist analogue enter; and whereas it's attainable to run 'naked metallic' software program on a Raspberry Pi, software program operating below a general-purpose working system like Linux will not be effectively suited to low-latency management of particular person I/O pins," he said.

"Many hobbyist and industrial purposes pair a Raspberry Pi with a microcontroller. The Raspberry Pi takes care of heavyweight computation, community entry, and storage, whereas the microcontroller handles analogue enter and low-latency I/O and, typically, supplies a really low-power standby mode."

The brand new RP2040 board is the primary piece of in-house silicon designed by Raspberry Pi, with Adams explaining that creating the chip from scratch was the one method the corporate may obtain what it needed from its first microcontroller-class product. Particularly, to mix high-performance and versatile I/O with an accessible worth level.

The result's what Adams labelled "an extremely highly effective little chip". The RP2040 contains a 133MHz dual-core Arm Cortex M0+ CPU, 264KB of on-chip RAM and assist for as much as 16MB of off-chip Flash reminiscence, USB 1.1 and 30 GPIO pins, 4 of which can be utilized as analogue outputs.

All of that is crammed right into a diminutive 7 x 7mm bundle containing simply two sq. millimetres of 40nm silicon. The RP2040 is good of machine-learning purposes, so Raspberry Pi has created a port of each TensorFlow Lite and MicroPython to assist customers get began.

For energy customers, Raspberry Pi supplies a whole SDK of the C programming language in addition to Visible Studio Code integration.

The Raspberry Pi Pico board itself pairs the RP2040 with 2MB of Flash reminiscence. The facility provide chip helps enter voltages from 1.5 to five.5V, which means it may be powered by USB or by way of AA or lithium-ion batteries. The board measures in at 21mm x 51mm and contains a single push button that can be utilized in addition the Pico into mass storage mode.

Clients should purchase the Raspberry Pi Pico on-line from in the present day. Alternatively, they will exit and decide up the newest version of Hackspace journal, which comes with a free Pico board.

A wide range of equipment designed for the RP2040 platform by Adafruit, Arduino, Pimoroni, and Sparkfun are additionally accessible for pre-order.
