Today, the Raspberry Pi Foundation launched its first microcontroller-level product: the Raspberry Pi Pico, built on a brand new RP2040 chip, priced at just $4.

If you have used Arduino or some development boards that support MicroPython, you should be familiar with this type of microcontroller product (MCU). The ultra-low power consumption, extremely low I/O latency, low price, and simple control methods make the Raspberry Pi Pico as easy to use as other MCUs, and it can be widely applied.

The RP2040 on Raspberry Pi Pico

– The RP2040 chip is in a 7×7mm QFN-56 package, with the following specifications:– Dual-core Arm Cortex-M0+ @ 133MHz– 264KB SRAM and 2MB of onboard flash memory– Supports up to 16MB of external flash via dedicated QSPI bus– DMA controller– 30 GPIO pins, 4 of which can be used as analog inputs– 2 UART, 2 SPI controllers, and 2 I2C controllers– 16 PWM channels– USB 1.1 host and device support– 8 programmable I/O (PIO) state machines for custom peripheral support– USB mass storage boot mode supporting UF2 for drag-and-drop programming

The Raspberry Pi Foundation stated that the Raspberry Pi Pico was developed in collaboration with Damien George, the creator of MicroPython. It is evident that the design of the entire development board has absorbed many excellent features from the pyboard.

Additionally, Adafruit and Pimoroni have also joined the RP2040 ecosystem. They have 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 believed that the Raspberry Pi Pico and the RP2040 ecosystem will gradually enrich.
