The Wio RP2040 Module is Seeed Studio’s self‑developed wireless module based on the RP2040 dual‑core MCU and ESP8285 Wi‑Fi chip. It is designed with the Raspberry Pi Pico as a prototype, meaning developers can control pins just like a Pico board using the Thonny editor. With its castellated pads and ultra‑small footprint, it can be soldered directly onto PCB backplanes for embedded IoT applications. Key Features Highly integrated Wi-Fi SoC: Features a powerful ESP8285 Wi-Fi chip, supporting 802.11 b/g/n, 2.4~2.4835GHz up to 72.2 Mbps, and AP & Station mode. Powerful CPU with High Performance: Dual-core 133MHz Raspberry Pi RP2040 processor with 264KB SRAM, 2MB Flash, and a clock speed up to 133 MHz. Flexible Compatibility and User-Friendly: Comprehensive C/C++/MicroPython SDK, software examples, and documentation support, fully compatible with the Thonny editor. Extremely Compact Size: Measures only 18.0 x 28.2 x 1.0mm with a 32-pin SMT package. Global Certifications: Fully FCC and CE certified for reliable deployment. Product Description The Wio RP2040 module is engineered with the RP2040 + ESP8285 Wi-Fi chip combination. The onboard Wi-Fi chip provides stable wireless connectivity, making it a perfect fit for your IoT platform choice. This RP2040 Wi-Fi module supports the Thonny code editor used by Raspberry Pi Pico. You can upgrade your original Pico project to a Pico IoT project with a few simple lines of code! The module adopts a stamp hole (castellated) package and small form factor, allowing you to solder the module onto various PCB boards with ease. In addition to the high-performance MCU, the board features rich interfaces, including 32 GPIO pins (20 pins support PIO and PWM), 2 UART, 4 ADC, 2 SPI, and 2 I2C. Several pins can be multiplexed, such as GP12 and GP13, providing flexible I/O functions. The Wio RP2040 module also includes a USB PIN, which can be easily connected to a USB interface for power and data. The Wio RP2040 module is fully compatible with MicroPython, which means you can control hardware devices without professional electronic engineering knowledge by using simple code!
