More info


X-NUCLEO-IDW01M1 is a WiFi shield with the SPWF01SA module designed for use with STM32 Nucleo plates . The SPWF01SA module has CE, IC and FCC certificates, is energy-saving, operates in WiFi networks b / g / n, has a built-in SMD antenna. The SPWF01SA module is equipped with 1 MB Flash memory, thanks to which there is the possibility of wireless firmware updates (over-the-air). The module's firmware contains an IP stack, can create up to 8 TCP / UDP sockets, can generate dynamic Web pages (SSI) and use the REST API (get and post methods) to receive and transfer data to the cloud. The module can work simultaneously as a server and a client. The module can use encrypted TLS / SSL connections. The module can work as a WiFi (STA), IBSS or miniAP client (access point with the possibility of joining up to 5 clients). X-NUCLEO-IDW01M1 communicates with the STM32 Nucleo board via the UART interface and is controlled by AT commands. X-NUCLEO-IDW01M1 fits ST morpho and Arduino UNO R3 connectors.
