Pico
The Raspberry Pi Pico is a microcontroller board based on the Raspberry Pi RP2040 microcontroller chip.
Figure 1. The
Raspberry Pi Pico
Rev3 board.
Raspberry Pi Pico has been designed to be a low cost yet flexible development platform for RP2040, with the following
key features:
RP2040 microcontroller with 2MByte Flash
Micro-USB B port for power and data (and for reprogramming the Flash)
40 pin 21x51 '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 3 are ADC capable
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
High quality, low cost, high availability
Comprehensive SDK, software examples and documentation
For full details of the RP2040 microcontroller please see the RP2040 Datasheet, however the headline features are:
Dual-core cortex M0+ at up to 133MHz
On-chip PLL allows variable core frequency
264kByte multi-bank high performance SRAM
