Key features include: RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz 264kB of SRAM, and 2MB of on-board flash memoryRaspberry Pi Pico exposes 26 multi-function GPIO pins from a total of 36 GPIO pins available in RP2040 microcontroller. Out of these 26 pins, 23 pins are digital pins, and only 3 pins have analog read capability. These digital pins are marked as GP0, GP1, and up to GP22. GP23, GP24, and GP25 are not exposed on the pinout. Therefore cannot be used.Raspberry Pi has In-built UART which can be used for serial communication with other devices like computer, GSM, GPS modules, etc.Talk to Your Pico Over Serial | Raspberry Pi Pico UART Tutorial 22,332 views Mar 5, 2021 In this video, we dive deep into how to use the serial port on the RP2040 Raspberry Pi Pico....16 de jul. de 2021 ...
