Description
Raspberry Pi Pico W Wifi
This is a Raspberry Pi Pico W Board. Each product is powered by the RP2040, a Raspberry Pi-designed chip with two ARM Cortex-M0 + cores clocked at 133MHz, 256KB RAM, 30 GPIO pins, and a variety of interfacing options. This is paired with 2MB of onboard QSPI Flash memory for storing code and data.
The Raspberry Pi Pico W has an onboard buck-boost SMPS that can generate 3.3V (to power the RP2040 and external circuitry) from a wide range of input voltages (1.8 to 5.5V). This gives you a lot of options for powering the unit, such as a single lithium-ion cell or three AA cells in series. Battery chargers can be easily integrated into the Pico W power chain as well.
