Lastly, it can also support all types of communication like UART, I2C, SPI, and PWM. In addition to this, it also has 4 ADC channels for controlling Analog devices.

RP2040 comes in the QFN-56 Package, out of which 30 GPIO pins are available. Moreover, it has 264 KB of SRAM with six independent banks and can support up to 16 MB of an external flash. I do not have that version at this instant, so all the information regarding PICO W will be updated later. PICO W is the Wi-Fi inbuilt version of the Raspberry Pi PICO. There is another version of Raspberry Pi PICO available which is launched recently, i.e., PICO W. Unlike ESP32, its clock frequency cannot be adjusted, also the pin numbering is sometimes complicated PICO.

Firstly, RP2040 is built around Dual-Core ARM Cortex M0+ that runs at a clock frequency of 133MHZ. RP2040 is a microcontroller from the same Raspberry Pi Organization, moreover is it cheap and as capable as an ESP32. But as there is no on-board storage hence this value is 0, but it can be calculated as the floor value of log(non-volatile/16 KB). Moreover, the last 0 in the name stands for the onboard non-volatile storage. In addition to this, it also defines the storage and memory of the IC that can be recognized as follows, 4 indicates the floor value or largest integer value of log(RAM/16 KB) that comes to 4. RP stands for Raspberry Pi, 2 indicates that the IC has Dual Core, 0 type of core i.e., M0+. The RP2040 IC name also has some other meanings, that can define many things about IC architecture. Raspberry Pi PICO is based on RP2040 Microcontroller that can be compared with ESP32 boards in head-to-head competition, but I recommend both for a hobbyist. For this, Raspberry Pi org has released a $4 Microcontroller board, Raspberry Pi PICO. Moreover, many of us have seen simple projects like interfacing some sensors and other stuff like this, but buying a $35 board is not smart. Also, as this is compatible with python, it can be used by a new programmer who lacks C/C++. Raspberry Pi PICO is similar to other Boards like Arduino UNO, ESP32, ESP8266, or STM32, but it is quite more powerful than these. Raspberry Pi 3 and Raspberry Pi 4 are the latest versions of these single-board computers. Until now, many of us have heard about the most famous single-board computer, Raspberry Pi boards.
