Raspberry Pi Rolls Out $4 Microcontroller - Pico

The brand new chip is built on RP2040.

Recently, Raspberry Pi launched its first microcontroller-class product: Raspberry Pi Pico. The brand new chip is built on RP2040 and is priced at just $4.

Raspberry Pi said that RP2040 builds on the lessons the company has learned from using other microcontrollers in its products, from the Sense HAT to Raspberry Pi 400. "It’s the result of many years of hard work by our in-house chip team."

Raspberry Pi said that Raspberry Pi Pico is its low-cost breakout board for RP2040. It pairs RP2040 with 2MB of Flash memory, and a power supply chip supporting input voltages from 1.8-5.5V. You can power Pico from a wide variety of sources, including two or three AA cells in series, or a single lithium-ion cell. The small chip exposes 26 of the 30 GPIO pins on RP2040, including three of the four analogue inputs, to 0.1”-pitch pads.

RP2040 is a 7 × 7 mm QFN-56 package containing just two square mm of 40 nm silicon. It features Dual-core Arm  Cortex-M0+ @ 133MHz, 264KB  of on-chip RAM, Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus, and DMA controller.

Other components of RP2040 include Interpolator and integer divider peripherals, 30 GPIO pins, 4 of which can be used as analogue inputs, 2 × UARTs, 2 × SPI controllers, and 2 × I2C controllers, and 16 × PWM channels.
