In terms of hardware, the Raspberry Pi Pico W is identical to its predecessor; it sports the same RP2040 Arm Cortex M0+ Dual-Core SoC, which is based on TSMC’s 40nm low power manufacturing process. This chip clocks up to 133MHz and also packs in 264KB of SRAM. There is 2MB of onboard flash storage thrown in, as well. Additionally, the machine features a 40-pin GPIO just like the original Pico from 2021. The onboard micro USB controller can be used for data transfer and receiving power.
The Wi-Fi module on the Raspberry Pi Pico is the Infineon CYW43439 wireless that, apart from supporting 2.4GHz Wi-Fi networks, also adds Bluetooth Classic and Bluetooth Low-Energy support. However, as of now, Raspberry has chosen not to enable Bluetooth capability in the machine. The company does not rule out the possibility of enabling Bluetooth further down the line, though.
With over 2 million Raspberry Pi Pico boards in the hands of consumers, the company expects its new model to enjoy similar success. The company also believes that the ongoing chip shortage has been among the prime reasons for the popularity of the RP2040-based Raspberry Pi Pico. The Pico W, thanks to its newfound wireless capability, will continue to be a great product that can power many IoT-based applications and DIY smart home needs. With a price tag of $6, the Raspberry Pi Pico W costs just $2 more than its predecessor. As the ecosystem for starter microcontrollers evolves, the $6 you spend on the Pico W will definitely be a worthwhile investment.
