Specs

Raspberry Pi Pico has been designed to be a low-cost yet flexible development platform for RP2040, with the following key features:

• Dual-core cortex M0+ at up to 133MHz
  • On-chip PLL allows variable core frequency
• 264kB multi-bank high-performance SRAM
• External Quad-SPI Flash with eXecute In Place (XIP) and 16kB on-chip cache
• High-performance full-crossbar bus fabric
• On-board USB1.1 (device or host)
• 30 multi-function General Purpose IO (4 can be used for ADC)
  • 1.8-3.3V IO Voltage (NOTE Pico IO voltage is fixed at 3.3V)
• 12-bit 500ksps Analogue to Digital Converter (ADC)
• Various digital peripherals
  • 2 × UART, 2 × I2C, 2 × SPI, 16 × PWM channels
  • 1 × Timer with 4 alarms, 1 × Real Time Counter
• 2 × Programmable IO (PIO) blocks, 8 state machines total
  • Flexible, user-programmable high-speed IO
  • Can emulate interfaces such as SD Card and VGA

• RP2040 microcontroller with 2MB Flash
• Micro-USB B port for power and data (and for reprogramming the Flash)
• 40 pin 21×51 ‘DIP’ style 1mm thick PCB with 0.1″ through-hole pins also with edge castellations
  • Exposes 26 multi-function 3.3V General Purpose I/O (GPIO)
  • 23 GPIO are digital-only, and three are ADC capable
  • It can be surface mounted as a module
• 3-pin ARM Serial Wire Debug (SWD) port
• Simple yet highly flexible power supply architecture
  • Various options for easily powering the unit from micro-USB, external supplies, or batteries
