![]() ![]() Communication Peripheralsīoth Raspberry Pi Pico & Arduino development boards provide several communication interfaces such as I2C(Inter-Integrated Circuit), UART(Universal Asynchronous Receiver / Transmitter), SPI(Serial Peripheral Interface), 1-Wire, Wi-Fi & Bluetooth. The RP2040 microcontroller on Raspberry Pi Pico has a decent clock speed of 133 MHz which should be enough for hobbyists. While such a speed is often enough for many applications in embedded systems, a higher clock rate may be required for advanced projects such as audio processing.Īmong the boards manufactured by Arduino, Arduino Potenta H7 has the highest clock speed of 480MHz on the Cortex-M7 core. In Table 3, we see that Arduino UNO is limited by its clock speed of only 16MHz. Table 3: Clock Speeds of Arduino & Raspberry Pi Pico boards The clock speed determines how fast instructions execute in a microcontroller. In a microcontroller, the clock is used to synchronize the processor, data bus, address bus, memory, peripherals, and I/O. Table 2: Details of microcontrollers in Arduino & Raspberry Pi Pico boards. The table below shows the differences between Raspberry Pi Pico & different Arduino boards in terms of CPU and memory differences. The Arduino UNO, which is the most popular board, is based on the AVR 8-bit architecture. Arduino boards use various microcontrollers based on AVR and ARM architectures. Raspberry Pi Pico W features an RP2040 microcontroller which has a dual-core ARM Cortex-M0+ processor. The development boards have different microcontrollers whose specifications decide their usefulness. While most Arduino boards provide 6 or more ADC(Analog-to-Digital Converter) pins, Raspberry Pi Pico W has only 3 easily accessible analog input pins for ADC. Arduino Portenta H7 also has 2 DAC channels of 12 bits. The Arduino DUE has 2 analog output pins. ![]() Analog output is useful to produce waveforms.īut some boards such as the Arduino Nano 33 IoT and Arduino MKR 1000 WiFi feature an analog output pin with a 10-bit DAC(Digital-to-Analog converter). In most development boards, we need to rely on the PWM output pins for analog output. The table below shows the number of GPIOs available for Raspberry Pi Pico and various Arduino boards against different functions. The General Purpose Input/Output(GPIO) pins in development boards can be configured as either input or output to connect and communicate with external devices or peripherals. ![]() The RPi Pico W has Wi-Fi & Bluetooth on-board which makes it a suitable choice for IoT development. It has good documentation, a supportive community, and is an alternative to Arduino and Espressif boards. Raspberry Pi Pico and Raspberry Pi Pico W are 40-pin development boards developed by the Raspberry Pi Foundation. ESP32), Nordic Semiconductor, and many more can be programmed with the Arduino IDE. Boards from other manufacturers such as Espressif(e.g. Among the development boards, Arduino UNO, Arduino Nano, and Arduino Mega are popular in the hobby community.Īrduino IDE is a beginner-friendly IDE that helps newbies get started easily with development boards. ![]() The Arduino ecosystem comprises several development boards and the Arduino IDE.
