Raspberry Pi Pico — RP2040 dual-core Cortex-M0+, 264KB SRAM, 2MB Flash cc2541 Parameter Value MCU STM32F401RET6 (Cortex-M4The Raspberry Pi Pico is the original low cost, high performance microcontroller board from Raspberry Pi, built around the RP2040 Raspberry Pis own silicon. With a dual core Arm Cortex M0+ processor, flexible I O, and support for both MicroPython and C C++, the Pico is an ideal platform for learning embedded systems, building IoT devices, and prototyping electronics projects. Note: the Pico does not include wireless connectivity for Wi Fi and
