Raspberry Pi Pico Microcontroller

Raspberry Pi Foundation launched (21-1-2021) its first microcontroller-class product called the Raspberry Pi Pico, Which only costs $4.

Raspberry Pi Pico includes the RP2040 chip (a dual-core ARM Cortex M0+ processor running at up to 133MHz), 2MB of Flash memory, 26 multifunction GPIO pins including three analog inputs, two UART, two SPI controllers, two I2C controllers, 16 PWM channels, and a USB 1.1 controller. There are also eight programmable I/O state machines allowing for custom peripherals, an accurate on-chip clock, temperature sensor, and low-power sleep and dormant modes.

There’s full support for programming in MicroPython or C/C++,

Key features include:

• RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom
• Dual-core Arm Cortex M0+ processor, the flexible clock running up to 133 MHz
• 264KB of SRAM, and 2MB of onboard Flash memory
• The castellated module allows soldering directly to carrier boards
• USB 1.1 with device and host support
• Low-power sleep and dormant modes

• Drag-and-drop programming using mass storage over USB
• 26 × multi-function GPIO pins
• 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels
• Accurate clock and timer on-chip
• Temperature sensor
• Accelerated floating-point libraries on-chip
• 8 × Programmable I/O (PIO) state machines for custom peripheral support
