To put it into perspective, $109 would buy 27 Raspberry Pi Pico boards. Retailing for в‚¬89.90 (excluding taxes) which is approximately $109, the Portenta H7 has a high price for the level of tech squeezed within it. The Portenta H7 blows the Raspberry Pi Pico out of the water in every way, except the price. The Portenta H7 also comes with WiFi, Bluetooth, camera interface and a GPU. With only 32KB of flash storage the Uno again falls short of the 2MB found on the Pico.Д«ut how does the Pico shape up against ArduinoвЂ™s flagship board the Portenta H7? Well the Portenta H7 features a dual core Arm Cortex M7 + M4 that can run up to 480 MHz and have up to 2MB of flash storage and 1MB of RAM. SRAM on the RP2040 is 264KB, again much more than the UnoвЂ™s 2KB. First of all, we have a dual core Arm Cortex M0+ running at up to 133 MHz, much faster than an UNOвЂ™s 16 MHz 328P. The RP2040 used in the Raspberry Pi Pico is a level above a typical microcontroller. Microcontrollers do not necessarily need multiple cores and fast speeds as they are typically used for a single part of a process. While the ATMega328 is never going to compete with an Arm processor, it is a reliable chip for projects, proven by the countless number of Arduino projects on offer.ДЄrm chips are becoming more common with microcontrollers, Adafruit, Seeed and SparkFun have all developed boards with Arm chips. For example ArduinoвЂ™s Portenta H7 has a dual core Arm Cortex M7+M4 CPU. The older and more popular Arduino boards are powered by Atmel chips such as the ATMega328P but the later boards now feature Arm CPUs. Winner: Raspberry Pi Pico SoC of Raspberry Pi Pico vs Arduino All of this from a $4 board means the Raspberry Pi Pico is a low cost вЂњSwiss Army knifeвЂќ of GPIO pins.

But what the Pico also offers are a series of programmable IO (PIO) pins which can be configured to simulate other interfaces / protocols such as WS2812 вЂњNeoPixelsвЂќ, they can also be used to offload complex tasks to a background process.

The Raspberry Pi Pico GPIO offers plenty of digital IO, three analog inputs and multiple I2C, SPI and UART connections. Adopting the DIP layout, the Raspberry Pi Pico provides us with an easy to use form factor which is easy to embed into a project. It is a more convenient package compared to the Raspberry Pi and Arduino Uno style layouts which favour a larger layout. The DIP package can be soldered into a carrier board, placed into a breadboard or stacked atop compatible addons. The DIP package is nothing new, Arduino boards such as the Micro have been using it for years. All 40 pins are broken out to standard pads and, around the perimeter, there are castellations which can be used to solder the Pico to a carrier board in a similar fashion to surface mount electronics. The Raspberry Pi Pico introduces a new form factor to the Raspberry Pi ecosystem, a 40 pin вЂDIPвЂ™ style PCB.
