Raspberry Pi Pico W: Ultra‑Low‑Power Wi‑Fi MCU for Edge Projects
The Raspberry Pi Pico W delivers a lightweight Wi‑Fi enabled microcontroller platform built around the RP2040 dual‑core ARM Cortex‑M0+ core. With on‑board 2 Mbit Flash and 264 kB SRAM, it runs deterministic real‑time workloads while maintaining a minimal power envelope. The integrated 802.11 b/g/n Wi‑Fi radio allows seamless IoT connectivity, making it ideal for wireless sensor nodes, smart home appliances, and wireless debugging setups.
Supporting a broad ecosystem of MicroPython, C/C++ SDKs, and a stack of pre‑built libraries, the Pico W provides developers with low‑level control and fast boot times. Its compact 21‑pin QFN package, robust 3.3 V operating range, and active low‑power states enable deployment in battery‑powered devices without sacrificing performance.
- Key Spec 1: RP2040 dual Cortex‑M0+ cores at 133 MHz, 264 kB SRAM, 2 Mbit QSPI Flash
- Key Spec 2: Integrated Infineon CYW43439 Wi‑Fi module, 2.4 GHz 802.11 b/g/n, up to 300 mA peak
- Key Spec 3: 20 GPIOs (15 PIO, 7 PWM, 3 I²C, 2 SPI, 2 UART, 1 ADC), 3.3 V logic
- Common Use Case: Wireless environmental monitoring system with low‑power sleep modes and OTA firmware updates
