The Raspberry Pi Foundation’s small computers can be used for anything from home cameras to cucumber sorters and now, the group is branching out into micro-controllers and custom silicon. Raspberry Pi Pico is the first step. It is a new $ 4 microcontroller that is smaller than the average pie, features a custom chip powerful enough to be used in machine learning projects (according to The Raspberry Pi Foundation), and is now on sale.
In its introductory blog post, the company states that today’s raspberry paste is already frequently used with a small microcontroller:
The Raspberry Pi takes care of heavyweight computation, network access, and storage, while the microcontroller handles analog input and low-latency I / O and offers, at times, very low-power standby modes.
Now, the company has its own.
In the first for the microcomputer manufacturer, the Pico is powered by a custom chip designed in-house called the RP2040. The Pico board features a new chip, 2 MB flash memory, a clickable button and a Micro USB Type B port. Here are the full specs of RP2040:
Dual-core arm Cortex-M0 + @ 133MHz
264KB on RAM chip (remember kilobytes?)
Supports off-flash flash memory up to 16MB via dedicated QSPI bus
Interpolar and integer divider peripheral
30 GPIO pins, 4 of which can be used as analog inputs
2 × UARTs, 2 × SPI controllers and 2 × I2C controllers
16 × PWM Channel
1 × USB 1.1 controller and PHY, with host and device support
8 × Raspberry Pi Programmable I / O (PIO) State Machines
USB mass-storage boot mode with UF2 support for drag-and-drop programming
Those specs can go in one ear and out the other, but the best way to describe the potential for a new Raspberry Pi product is to use it in something cool. The Raspberry Pi Foundation is partnering with companies such as Arduino, Adafruit, and Pimoroni to integrate the new RP2040 chip into other boards and gadgets. The blog post announcing Pico has a complete list, but some notable ones are Pimouroni’s Picosystem game console, Adafruit’s Feather RP 2040 board and Arduino Nano RP2040 connect.
Raspberry Pi Pico is now available from approved resellers for $ 4. The microcontroller will also be given for free in February issues Hackspace magazine.
