Wi-Fi Shield for GS2101MIP

Wi-Fi Shield for Arduino-compatible Boards


The GS2101 Wi-Fi Shield is a Wi-Fi module-based adapter board derived from and compatible with Arduino form factor. The Wi-Fi Shield is designed to plug into Arduino-compatible boards that contain a microcontroller (MCU), such as the Freedom development kits from NXP: FRDM-K22F, FRDM-KL25Z, FRDM-KL46Z, FRDM-K64F or boards from other MCU vendors that are derived from Arduino. The Wi-Fi module interfaces to the host MCU using UART or SPI interfaces. The Shield provides the means to evaluate the capabilities of GainSpan’s low-power Wi-Fi modules and Serial-to-Wi-Fi embedded software, as well as develop software for MCU host-based Wi-Fi enabled devices. The Shield supports the IEEE 802.11b/g/n protocols.

Our Wi-Fi Shield ships with Serial-to-Wi-Fi software preloaded on the module. However, customers should load the latest version of the module firmware that is the most suited for their application from the GainSpan portal, or program the board with custom binaries built using the GainSpan SDK-Builder or GS2000 SDK.
