Raspberry Pi releases the Pico 2W, a $7 wireless-capable microcontroller board

Get to know Raspberry Pi Pico 2Wa tiny board designed around a microcontroller that permits you to construct large-scale hardware projects. Raspberry Pi once more uses its own, RP2350 well documented microcontroller.

But what’s a microcontroller again? As the name suggests, microcontrollers will let you control other components or electronic devices. Regular Raspberry Pis are general-purpose single-board computers, while microcontrollers are specifically designed to interact with other components.

Microcontrollers are often low-cost, small and really energy efficient. As you may see in the image above, the Pico 2W has dozens of input and output pins (small yellow holes around the board) on its sides that it uses to speak with other components.

Hobbyists normally start creating a microcontroller-based project with a file bread cutting board to avoid soldering. Later they will solder the microcontroller to other parts.

Unlike traditional Raspberry Pi computers, microcontrollers don’t run a full-fledged operating system. Your code runs directly on the chip.

In addition to C and C++, Pico 2 W supports MicroPython, a Python-inspired language for microcontrollers, for programming purposes. The latest board maintains hardware and software compatibility with previous generation boards.

The latest $7 Pico 2W processor features a dual-core, dual-architecture processor running at 150MHz. When developing a microcontroller, you may make a choice from a pair of Arm Cortex-M33 cores and a pair of open-hardware Hazard 3 RISC-V cores.

Arm Cortex-M33 cores are widely utilized in the microcontroller world, but some may prefer RISC-V cores. Everything could be configured in software, so that you do not have to decide on one microcontroller over one other when ordering latest boards.

The Pico 2W has 4MB of onboard flash memory for code storage, while the RP2350 has 520KB of onboard SRAM. I’ll say it again: this just isn’t a computer beast. It’s a microcontroller!

In terms of wireless capabilities, Pico 2W supports Wi-Fi (2.4 GHz 802.11n) and Bluetooth 5.2. It could be nice to get 5 GHz support for versatility, but possibly we are able to achieve that in the next version.

If you do not need wireless features for price or compliance reasons, Raspberry Pi also offers Pico 2 without this feature for $5.

Raspberry Pi products are increasingly utilized by firms involved in industrial and electronics production. When Raspberry Pi became a public company this yr, it reported that the industrial and embedded segment accounted for 72% of its sales.

This might be why you may buy single pieces of Pico 2 boards in addition to spools of 480 pieces. This is what the Pico 2 microcontroller board spool looks like:
