Recently, the Raspberry Pi Foundation published a microcontroller development board, the Raspberry Pi Pi Pico, which is smaller than the ordinary Raspberry Pi Pi and costs only $4. , Built-in powerful customized chip, now on sale. According to the Raspberry Pi Foundation, the Raspberry Pi Pi Pico is sufficient for projects such as device learning.
The company explained that the Raspberry Pi Pi can handle heavyweight computing, network access, and storage, while the Raspberry Pi Pi Pico microcontroller can handle analog input and low-latency I/O, and sometimes provides very low-power standby. mode.
This is also the first time that the microcomputer producer Raspberry Pi Foundation uses an internal custom chip called RP2040 to power the Raspberry Pi Pi Pico. The Raspberry Pi Pi Pico features the latest chip, a 2MB flash memory, a single click button, and a Micro USB Type B port.
The built-in RP2040 microcontroller chip is furnished with a dual-core ARM Cortex M0 + processor, running at a frequency of up to 133MHz, built-in 264KB of SRAM, and a dedicated QSPI bus can support up to 16MB of off-chip flash memory; it has 30 GPIO pins, of which 4 can be used as analog inputs.
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. Several of the notable ones are Pimoroni’s PicoSystem game console, Adafruit’s Feather RP 2040 development board, and Arduino’s Nano RP2040 Connect device.
