STM67 Wireless Module Breakout

The STM67 Wireless Breakout adds Wi-Fi 6 and Bluetooth LE 5.4 connectivity to STM32-based projects, making it ideal for IoT devices, wireless sensing, and low-power embedded applications.

Wi-Fi on STM32? Now, it's possible! The STM67 Wireless Breakout gives developers instant access to the STMicroelectronics ST67W611M1, a low-power Wi-Fi 6 and Bluetooth LE 5.4 combo coprocessor native to STM32 platforms! It's placed on a convenient, breadboard-friendly breakout. The ST67W611M1 operates as a dedicated wireless coprocessor, leaving your STM32 host MCU free to run application logic. The board comes pre-flashed with the X-CUBE-ST67W61 Expansion Software Package, so you can start developing immediately out of the box. On the Wi-Fi side, the chip supports IEEE 802.11b/g/n/ax (Wi-Fi 6) with up to 17Mbps TCP throughput, WPA3 security, and advanced features like MU-MIMO, OFDMA, and Target Wake Time (TWT) for battery-powered applications. Bluetooth LE 5.4 runs concurrently alongside Wi-Fi, supporting speeds up to 2Mbps across peer-to-peer, broadcast, and mesh topologies. Both radios share a built-in PCB antenna with all required RF components already on-module. The breakout runs on a single 3.3V supply and connects to your microcontroller via SPI (up to 40MHz) or UART, supporting IO voltages of 1.8V or 3.3V for full STM32 compatibility. An onboard 32.768kHz crystal oscillator and a bank of decoupling capacitors ensure stable, noise-free operation right out of the box. Deep sleep current is just 90µA, making it well suited for low-power applications. Features
