On January 22, the Raspberry Pi Foundation released the latest Raspberry Pi Pico, a low-cost, high-performance microcontroller development board. The new product is smaller than ordinary Raspberry Pi and priced at only US$4. It is available now Sales.
According to the Raspberry Pi Foundation, Pi Pico is sufficient for machine learning and other projects, can handle analog input and low-latency I/O, and can provide a very powerful low-power standby mode.
Raspberry Pi Pico is a convenient, flexible, and easy to use open source electronic prototype platform. Launched by the Raspberry Pi Foundation. Unlike any previous Raspberry Pi, Raspberry Pi Pico is positioned as a high-performance single-chip controller. It is dedicated to solving the deficiencies in the hardware control field that Raspberry Pi is not good at. It is to complement Raspberry Pi products. An important part of functional ecology.
The overall size of Raspberry Pi Pico is only 21 x 51 mm, using self-developed RP2040 microcontroller chip, equipped with Arm Cortex M0+ dual-core processor, running at 133MHz, built-in 264KB of SRAM and 2MB onboard flash memory, onboard 26 3.3 V multifunctional general-purpose GPIO pin, with 2 SPI, 2 I2C, 2 UART, 3 12-bit ADC, 16 controllable PWM channels.
If you have used Arduino or some development boards that support MicroPython, you should be familiar with this kind of microcontroller products (MCU). Ultra-low power consumption, extremely low I/O latency, low price and simple control methods make Raspberry Pi Pico as easy to use as other MCUs and can be widely used.
– The RP2040 chip is packaged in a 7×7mm QFN-56 package. The specific specifications are as follows:
– Dual-core Arm Cortex-M0 + @ 133MHz
– Built-in 264KB SRAM and 2MB of on-board flash memory
– Supports up to 16MB of off-chip flash memory through a dedicated QSPI bus
– DMA controller
– 30 GPIO pins, 4 of which can be used as analog inputs
– 2 UARTs, 2 SPI controllers and 2 I2C controllers
– 16 PWM channels
– USB 1.1 host and device support
– 8 Raspberry Pi Programmable I/O (PIO) state machine for custom peripherals support
-support UF2 USB mass storage boot mode for drag-and-drop programming
According to the Raspberry Pi Foundation, the Raspberry Pi Pico was developed in cooperation with Damien George, the creator of MicroPython. It can be seen that the design of the entire development board has absorbed many of the excellent features of pyboard.
In addition, Adafruit and Pimoroni also participated in the RP2040 ecosystem. They launched similar products:
Adafruit Feather RP 2040
Adafruit ItsyBitsy RP 2040
Arduino Nano RP2040 Connect
Pimoroni PicoSystem
Pimoroni Pico Explorer Base
SparkFun Thing Plus – RP2040
SparkFun MicroMod RP2040 Processor
SparkFun Pro Micro – RP2040
It is understood that the Raspberry Pi Foundation is working with companies such as Arduino, Adafruit, and Pimoroni to integrate the RP2040 chip into other circuit boards and devices. Some of the notable ones are Pimoroni's PicoSystem game console, Adafruit's Feather RP 2040 development board, and Arduino's Nano RP2040 Connect device.
It is believed that the ecology of Raspberry Pi Pico and RP2040 will gradually enrich.
