Raspberry Pi expands its family of ultra-low-cost microcontrollers with the debut of three new Pico models. Perhaps DIYers will be most excited about the Pico W, an exact replica of the original Pico save for the addition of 802.11 Wi-Fi connectivity, a feature that will greatly enhance the utility of this board. This important addition adds $2 to the price, bringing the Pico W down to just $6.

The component that gives the Pico wireless connectivity is an Infineon CYW43439, with support for the legacy 802.11n protocol (Wi-Fi 4). Do a quick search and you’ll find that the chip supports Bluetooth and Bluetooth Low-Energy (LE); Oceanre not activated on the Pico W at launch but may be added in the future.

Priced between the original and the Pico W, the $5 Pico H adds pre-assigned headers and a 3-pin debug connector to the original Pico. The Pico WH combines these features—Wi-Fi, 3-pin debugging, and pre-allocated headers—and costs $7.

With these three additions, Raspberry Pi hopes to continue the momentum of the original Pico. Launched in early 2021, the Pico is based on an RP2040 microcontroller, housing a pair of 144MHz Arm Cortex-M0+ CPU cores and 264kB of memory. It is a low-power, low-energy board intended for single-purpose IoT devices such as sensors, motors, and other peripherals. Raspberry Pi says it’s sold just under two million pico boards and so on The RP2040 microcontroller is used in various third-party products and applications.

“We have always believed that RP2040 would be excellent for commercial and industrial applications, but global semiconductor shortages have greatly accelerated adoption,” wrote founder Eben Upton in a blog entry. “With millions of units available today and a pipeline for tens of millions more, designers who have been let down by their current suppliers have a perfect excuse to experiment.”

The new Raspberry Pi Pico W is only $6

These three additions, most notably the Pico W, add even more versatility to Raspberry Pi’s most accessible microcontroller. They’re worthwhile upgrades that are likely to sell by the millions to students, engineers, and tinkerers. Early units sent to developers have already been converted into a garage door sensor (see the video above), a notification system and a WiFi network scanner.
