SPI Extend Click is a compact add-on board for applications that require extending the SPI communication bus over a long distance. This board features the LTC4332, an SPI slave extender device, from Analog Devices. Using a ±60V fault protected differential transceiver, the LTC4332 can transmit SPI data, including an interrupt signal, up to 2MHz over two twisted-pair cables. The extended common-mode range and high common-mode rejection on the differential link provide tolerance to large ground differences between nodes. This Click board™ also provides a control interface using a separate slave select for configuration and fault monitoring. All these features make SPI Extend Click an excellent choice for various applications that require extending the SPI bus over a long distance, such as industrial control, sensor installations, lighting and sound system control, and more.

SPI Extend 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.

RF Meter Click is a compact add-on board that measures radio frequency power. This board features the AD8318, a logarithmic detector/controller from Analog Devices. It covers a frequency span from 1MHz up to 8GHz over a 60dB range, approximately. The AD8318 acquires the signal over an external antenna, which is then processed by the logarithmic detector of the AD8318. The resulting voltage of the AD8318 is then fed into an MCP3201, a 12-bit ADC with SPI serial interface for further processing. This Click board™ makes the perfect solution for testing equipment, including RF transmitters or relays. It enables monitoring and measuring frequency levels to ensure proper functioning and leak detection.
