Espressif has also released open-source Linux drivers on GitHub supporting Wi-Fi station mode over PCIe and Bluetooth BR/EDR/BLE over USB, with AP mode, SDIO, UART Bluetooth, and suspend/resume still pending. The chip targets host-based wireless systems via PCIe 2.0 or SDIO, likely appearing in M.2 modules competing with MediaTek and Intel offerings. Neither the chip nor the M.2 module are currently available for purchase. ## Full article daily.dev links to this article rather than hosting it.
