Introducing the New Raspberry Pi Pico W, the upgraded Raspberry Pi Pico now with Wireless.

$6 for a board to rival the ESP8266?
The Raspberry Pi Foundation's own $4 board uses their own RP2040 microcontroller, built on TSMC’s 40nm low-power process, and incorporating two 133MHz Arm Cortex-M0+ cores, 264kB of on-chip SRAM, and our unique programmable I/O subsystem, for an additional $2 they will now include wireless on your Pico!

Where will my Pico W Wireless work?

The Raspberry Pi Pico W Wireless is compliant in the EU and US.

Raspberry Pi Pico W Specifications

Raspberry Pi Pico W has been designed to be a low cost yet flexible development platform for RP2040, with a 2.4GHz wireless interface and the following key features:

• RP2040 microcontroller with 2MB of flash memory

• On-board single-band 2.4GHz wireless interfaces (802.11n) • Micro USB B port for power and data (and for reprogramming the flash)

• 40 pin 21mmx51mm 'DIP' style 1mm thick PCB with 0.1" through-hole pins also with edge castellations

◦ Exposes 26 multi-function 3.3V general purpose I/O (GPIO)

◦ 23 GPIO are digital-only, with three also being ADC capable

◦ Can be surface-mounted as a module

• 3-pin Arm serial wire debug (SWD) port

• Simple yet highly flexible power supply architecture

◦ Various options for easily powering the unit from micro USB, external supplies or batteries

• High quality, low cost, high availability

• Comprehensive SDK, software examples and documentation For full details of the RP2040 microcontroller please see the RP2040 Datasheet book. Key features include:

• Dual-core cortex M0+ at up to 133MHz ◦ On-chip PLL allows variable core frequency

• 264kB multi-bank high performance SRAM

• External Quad-SPI flash with eXecute In Place (XIP) and 16kB on-chip cache

• High performance full-crossbar bus fabric

• On-board USB1.1 (device or host)

• 30 multi-function general purpose I/O (four can be used for ADC) - 1.8-3.3V I/O voltage

• 12-bit 500ksps analogue to digital converter (ADC)

• Various digital peripherals
2 × UART,
2 × I2C
2 × SPI
16 × PWM channels
1 × timer with 4 alarms
1 × real time clock

• 2 × programmable I/O (PIO) blocks, 8 state machines in total
Flexible, user-programmable high-speed I/O
Can emulate interfaces such as SD card and VGA

Raspberry Pi Pico W PinOut

The Raspberry Pi Pico W has some hidden gems when breaking out the available features of the RP2040.

Now with headers!

In addition to launching the Raspberry Pi Pico W, news has been released of a Version of the Raspberry Pi Pico and Raspberry Pi Pico W with Headers as standard.

These will be known as the Raspberry Pi Pico H and Raspberry Pi Pico WH!

Does the Raspberry Pi Pico W have Bluetooth?
According to Eben Upton - "Eagle-eyed readers of datasheets will notice that CYW43439 supports both Bluetooth Classic and Bluetooth Low-Energy: we have not enabled Bluetooth on Pico W at launch, but may do so in the future."

Getting Started with the Raspberry Pi Pico W

"For C developers, today’s release of the Pico SDK includes wireless networking support. The network stack is built around lwIP, and uses libcyw43 from Damien George (of MicroPython fame) to communicate with the wireless chip. By default, libcyw43 is licensed for non-commercial use, but Pico W users, and anyone else who builds their product around RP2040 and CYW43439, benefit from a free commercial-use license"
