The Raspberry Pi Basis’s tiny computer systems can be utilized for something from homemade cameras to cucumber sorters, and now, the group is branching out into microcontrollers and customized silicon. The Raspberry Pi Pico is step one. It’s a brand new $4 microcontroller that’s smaller than the common Pi, incorporates a customized chip highly effective sufficient for use in machine studying tasks (in line with The Raspberry Pi Basis), and is on sale now.
In its introductory blog post, the corporate explains that right now’s Raspberry Pis are already typically used alongside a smaller 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.
Now, the corporate has one among its personal.
In a primary for the microcomputer maker, the Pico is powered by a customized chip designed in home known as the RP2040. The Pico board options the brand new chip, 2MB of flash reminiscence, a clickable button, and a Micro USB Kind B port. Listed here are the RP2040’s full specs:
Twin-core Arm Cortex-M0+ @ 133MHz
264KB (keep in mind kilobytes?) of on-chip RAM
Help for as much as 16MB of off-chip Flash reminiscence by way of devoted QSPI bus
Interpolator and integer divider peripherals
30 GPIO pins, 4 of which can be utilized as analogue inputs
2 × UARTs, 2 × SPI controllers, and a pair of × I2C controllers
16 × PWM channels
1 × USB 1.1 controller and PHY, with host and system assist
8 × Raspberry Pi Programmable I/O (PIO) state machines
USB mass-storage boot mode with UF2 assist, for drag-and-drop programming
These specs would possibly go in a single ear and out the opposite, however the easiest way for instance the potential for a brand new Raspberry Pi product is to see it utilized in one thing cool. The Raspberry Pi Basis is partnering with corporations like Arduino, Adafruit, and Pimoroni to combine the brand new RP2040 chip into different boards and devices. There’s a complete checklist within the weblog put up asserting the Pico, however a couple of notable ones are Pimoroni’s PicoSystem sport console, Adafruit’s Feather RP 2040 board, and the Arduino Nano RP2040 Connect.
