GP0 to GP28 – General Purpose Input Output (GPIO) as well as Pulse Width Modulation (PWM)

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
