Note: This is the official Raspberry Pi Pico pre-soldered with a custom-made 40-way male header, it can be used for prototyping straight out of the box!

Note: Besides the pre-soldered headers, Raspberry Pi Pico H also comes with a pre-soldered right angle 1mm pitch-to-pitch connector. The Pins Layout and components placement are exactly the same as Raspberry Pico. And of course, it is also based on the same Raspberry Pi RP2040 Dual-Core, ARM Cortex-M0+ microcontroller.

1st MCU Board from Raspberry Pi – Pico

Released on the 21st of January 2021, the Raspberry Pi Pico is the 1st Microcontroller Development Board from Raspberry Pi Foundation. To ease the prototyping and project making, Raspberry Pi has come out with this pre-soldered header version, and it is called Pico H. This is official from Raspberry Pi Factory, all the way from the UK. Raspberry Pi has been very popular in producing Single Board Computer since the launch of Raspberry Pi 1 in February of 2012. Now, the engineering team has delivered another great news for digital makers around the world, a microcontroller development board.

What is Raspberry Pi Pico? A Microcontroller Development Board

What are the differences between the Raspberry Pi 4 Model B and this Raspberry Pi Pico? Well basically, the Raspberry Pi 4 Model B is a motherboard or single-board computer that you can use to play games, work, record data, browse the Internet, watch movies, like a media player, and many more. Raspberry Pi Pico is not designed to replace the Raspberry Pi 4 Model B (or similar board), it is more for physical computing projects where it controls anything from small electronic components, LEDs, and motors; to reading information from sensors, or communicating with other microcontrollers.

We probably have lots of microcontrollers in our house already. For example, a washing machine is controlled by a microcontroller; most likely our watch is too; there is also one in a microwave. Of course, all these microcontrollers already have their programs for the applications.

This Raspberry Pi Pico is a microcontroller board that can perform physical computing and can be easily reprogrammed over the USB connection.

Programming with MicroPython

As Python is the official programming language of Raspberry Pi OS, MicroPython is chosen to be one of the programming languages for Raspberry Pi Pico H. MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in constrained environments.

MicroPython is packed full of advanced features such as interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling, and more. Yet it is compact enough to fit and run within a microcontroller such as Raspberry Pi Pico H. MicroPython aims to be as compatible with normal Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system.

Programming loading of MicroPython into Raspberry Pi Pico H is effortless. Just connect the Pico H to any computer (including Raspberry Pi SBC) via USB, then drag and drop the file onto it. Yes! It is that easy! And Raspberry Pi Foundation has put together a downloadable UF2 file to let you install MicroPython more easily. Visit the Getting Started page by Raspberry Pi to download the necessary file.

Programming with C/C++

Not to worry, C/C++ is not forgotten 🙂 Raspberry Pi Pico H can also be programmed with C or C++ Programming language. To get started, please visit this page.

Work Seamlessly with Raspberry Pi Computer

You can always connect the Raspberry Pi Pico H to any preferred computer with Windows, macOS, and Linux that supports Python 3.0, yet connecting it with the Raspberry Pi Single Board Computer will be perfect as it is designed by the same team. The official Operating System, Raspberry Pi OS comes pre-installed with Thonny Python IDE which is ready for you to get started writing MicroPython code for Pico H. If you are using another OS (Windows, macOS, or other Linux distribution), please visit https://thonny.org/ to download the IDE and install it.

One of the Most Powerful MCU Dev Board

Dual-Core ARM Cortex M0+

Even though Raspberry Pico H is based on 1st silicon designed by the engineers from the Raspberry Pi Foundation, they never disappoint us. The launching of Raspberry Pi 4 Model B, CM4, and Raspberry Pi 400 proves that! Check out the features and specs of this tiny yet powerful microcontroller board. It comes with not one, but two cores (dual-core) of a 32-bit ARM Cortex M0+ processor. Flexible clock, yet configurable up to a maximum speed of 133MHz! This tiny MCU comes with a whopping 264 Kbyte of SRAM, and external Quad-SPI with a capacity of 2 MByte and eXecute in Place (XIP). Large RAM and Flash size enable you to write high-level programming languages like MicroPython for Raspberry Pi Pico H.

The Highlights:

The 1st MCU Platform by Raspberry Pi Foundation

1st Microcontroller Platform with the first in-house designed MCU silicon, RP2040! Yet, the Raspberry Pi team never stops surprising us with their work. This tiny board comes with a Dual-core 32-bit processor, ARM Cortex M0+ is an optimized superset of the Cortex-M0. The Cortex-M0+ has complete instruction set compatibility with the Cortex-M0 thus allowing the use of the same compiler and debug tools. The Cortex-M0+ pipeline was reduced from 3 to 2 stages, which lowers the power usage. On top of dual-core Cortex M0+, Raspberry Pi Pico comes with a reconfigurable clock speed, with the on-chip PLL (Phase-Locked Loop), which allows the MCU to be clocked at a maximum speed of 133MHz, of course, a configuration is necessary.

Pre-soldered Header Pins straight from Raspberry Pi Factory, Breadboard Friendly Out of The Box

Raspberry Pi Pico H comes with a custom-made header pin soldered, from the factory. It is beginner-friendly and Plug and Use on Breadboard out of the box. Raspberry Pi Pico H is extended out to 40-pin 21×51 DIP (Dual Inline Package) style, 1mm thick PCB with 0.1″ (100mil) through-hole pins. The width between holes is breadboard friendly, so students, makers, and engineers can use Pico H on a breadboard or any standard PCB board for development or prototyping. Awesome!

USB Micro B for Power and Data

Raspberry Pi Pico and Pico H incorporate the famous and commonly used USB Micro B receptor for both Power and Data. Just simply connect the USB Micro B cable to power it and load the program into it. No additional USB to Serial adapter is needed. Neat!

Peripheral Rich MCU

GPIO, ADC, UART, SPI, I2C of Raspberry Pi Pico

PWM Pins of Raspberry Pi Pico

Having exactly the pins assignment as Raspberry Pi Pico, the Pico H has 26 GPIO (3.3V) broken out for applications, it has more GPIO pins than Arduino UNO, Arduino NANO, or even Arduino MKR Zero. Among these 26 GPIOs, 3 can be configured as 12-bit ADC with 500ksps (kilo sample per second), 2 x UART, 2 x SPI, 2 x I²C, and up to 16 x PWM pin. Internally, it also comes with 1 x Timer with 4 alarms and 1 x Real Time Counter.  Not to forget the dual Programmable IO (PIO) peripherals which are flexible and user-programmable high-speed IO. It can emulate interfaces such as SD card and VGA.

Note:  The Raspberry Pi Pico and Pico H GPIOs run at 3.3VDC. The maximum voltage that the I/O pin can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could DAMAGE the board.

Large RAM and Flash Size

With 2 MByte of external QSPI Flash and 264 KByte of SRAM on Raspberry Pi Pico and Pico H, it will never prompt you about insufficient memory 🙂 Besides, the large size of RAM and Flash also enable Raspberry Pi Pico to be supported with higher programming languages such as MicroPython or even Javascript.

Drag and Drop Program Loading Method

With the USB Micro B receptor ready as the physical connection to a computer and the USB 1.1 device on the RP2040 (MCU), both the Raspberry Pi Pico and Pico H offer a simple and straightforward program loading method. It is like copying files from a drive to another drive. The Pico appears as USB mass storage when it is connected to the computer via the USB port! It becomes a USB drive! Write your code and drag the file into that USB drive. After the file is completely copied, the Pico will reboot and run the program 🙂 Easy right?

Support MicroPython, C, and C++

Python is one of the most famous and powerful programming languages nowadays. It is being used in many high-level applications such as AI (Artificial intelligence), DL (Deep Learning) and Web and Internet development, and more. Python is used successfully in thousands of real-world business applications around the world, including many large and mission-critical systems. MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on microcontrollers and in constrained environments. You will love it.

Besides MicroPython, Raspberry Pi Pico H also supports C and C++ Programming Langauge. Check out the C/C++ SDK for more info. All these programming languages are loaded into Raspberry Pi Pico H through USB Mass Storage which enables the simple drag and drop method (like copying a file to another drive).

Flexible Power Input

The USB Micro B receptor is the main power input to get the Raspberry Pi Pico H “running”, just connect the USB cable to any USB port and it will supply the power needed for the MCU to execute the program. In the case where you do not want to use the USB port, for example, a battery-powered, or a customized product; not to worry, Raspberry Pi Pico H comes with a flexible onboard buck-boost Switch Mode Power Supply (SMPS) that is capable of accepting 2 to 5VDC input and converts it to a stable 3.3V supply for the RP2040 MCU to operate. Simply awesome! The pin is VSYS (Pin 39). With a wide voltage range, Raspberry Pi Pico H can be powered by USB, 2 x AA battery, 2 x NiMH AA battery, 1 x 18650 Li-ion battery, or 1 x Cell LiPo battery!
