WiFi 5 Click is a compact add-on board that offers low-power wireless connectivity for any IoT application. This board features the GS1500M, an 802.11b/g/n low-power WiFi module from GainSpan. The GS1500M works at 2.4GHz and comes equipped with a trace antenna alongside a small u.Fl connector, allowing an external antenna to be used for improved range. The module includes a highly integrated 802.11b/g/n WLAN chip containing a MAC, baseband, and other functions and a GS1011 as a dual ARM7 processor platform. It also supports hardware encryption/decryption engines for WEP/WPA/WPA2, Adhoc, and WPS (Wi-Fi-protected setup) security protocols, allowing a secure connection. This Click board™ makes the perfect solution for the development of highly integrated and cost-effective applications, industrial wireless control, smart home applications, battery-powered applications, and many more.
DC Motor 17 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

WiFi 5 Click is based on the GS1500M, an 802.11b/g/n low-power WiFi module from GainSpan. The module supports WiFi PHI speeds of up to 72.2Mbps and can run the full WiFi TCP/IP network stack, so no stack implementation is required on the host MCU. The TCP/IP stack can be implemented on the host MCU; in that case, the WiFi 5 Click can be used just for signal throughput. It also supports peer-to-peer networking capabilities allowing WiFi devices to connect to each other without an access point, enabling easy transfer of content. The GS1500M module also comes with DSS modulation, CCK modulation, OFDM modulation, and 1x1 HT20, thus fully compliant with the 802.11b/g/n.
The dual ARM7 processor platform (GS1101) consists of two ARM7 44MHz chips, 384KB of embedded Flash memory, 128KB of RAM, and 512 bytes of RTC memory. The first ARM7 processor (WLAN CPU) is assigned to WLAN software. The master SPI (MSPI) of this CPU is used to communicate with an external flash memory device. This Click board™ also has an 8MB M25P80, a serial Flash memory from Micron. The second ARM7 is an APP CPU for networking software and incorporates an advanced microprocessor bus architecture (AMBA) system with AHB and APB. The AMBA APB allows the host MCU access to data, control, and status information, while AHB is a high-speed bus. The network RTOS, network stack, and customer application code can reside on this CPU.
The GS1500M has several system states. Besides Power OFF and Standby modes, there is also the System Configuration which is the transition system from the Standby, during which time the WLAN CPU is released from reset by the on-chip RTC, while the APP CPU is executed just before the Power-ON state. The Power-ON state is an active state where all system components can be running, or unused parts of the system can be in Sleep mode. There are two low-power states. In a Sleep state can go one or both of the CPUs as both control their own entry independently while the 44MHz crystal oscillator remains running. The Deep Sleep state means all CPUs and 44MHz crystal are turned off. Any enabled interrupt will make CPUs exit from Sleep or Deep Sleep states.
To communicate with the host MCU, WiFi, 5 Click uses the UART interface of the mikroBUS™ socket, with commonly used UART RX and TX pins and data rates of up to 921.6kbps. The GS1500M module can be reset via the RST pin, while pulling up the PRG pin module will enter the programming mode during the reset or power-on cycle. The GS1500M module supports a set of AT commands that can be used to develop applications. In addition, there are two user-configurable LEDs for the realization of visual detection of some statuses during operation.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
