The PI PICO has RP2040 chip onbaord is supported with both C/C++ and micro-python, meaning that if you’re a beginner and want to learn any of these languages, the Raspberry Pico would be the best product-option to start with.

Pi Pico is a micro-controller board based on in-house custom designed chip (RP2040) by Raspberry Pi in the UK. RP2040, the chip at the heart of Pico, is an ultra powerful Dual Core ARM Cortex-M0+ clocked at 133MHz with 256KB RAM, 2MB of on-board QSPI Flash memory for code and data storage. It also has 30 GPIO pins and lots of interfacing options including 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels. Moreover, 26 of the GPIO pins are multi-function, which means we can configure those pins to a different behavior like UART/I2C/SPI/GPIO.
