12/9/2023 0 Comments Raspberry pi pico vs arduinoJust like the larger Raspberry Pis and newer Arduino boards, the Pico uses a 3.3V GPIO. It could even work in conjunction with a regular Pi. On paper the Raspberry Pi Pico is not even a rival for the Raspberry Pi Zero, which itself costs only $5,, but the key difference between the two is that the Pico is not a Linux computer, rather it is a microcontroller like Arduino and is better for many projects. Castellated module allows soldering directly to carrier boards. 264KB of SRAM, and 2MB of on-board Flash memoryĢ6 × multi-function 3.3V GPIO pins 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels 8 × Programmable I/O (PIO) state machines for custom peripheral support. Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz. RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom. Raspberry Pi Pico Hardware Specifications We’ve also added other goodies like optimised floating-point libraries to the boot ROM, and a USB core which can be used in either master or slave mode.”Ĭould the Raspberry Pi Pico be the start of a new range of boards based upon the RP2040? Adams said the Foundation is waiting to see how things go with the first board. As well as the usual fixed peripherals (UARTs, I2C, SPI etc.) we also have a special bit of hardware called the PIO (Programmable I/O) unit, which is basically a very small, specialised, programmable state machine that can do high-speed, cycle accurate “bit banging” of I/O – this block can be used to offload many kinds of timing-critical pin-waggling tasks from the CPU(s) – we’ve had it emulating interfaces such as SD card, VGA and driving WS2812B LEDs. “We are offering some really unique features with the RP2040 chip - a dual core device (I’m not aware of other dual core microcontrollers at this price point) coupled to a high-performance bus matrix, meaning you can get full performance on both cores concurrently, and plenty of high-bandwidth RAM,” he said.
