Mic Click
R220.00 ex. VAT
Mic Click is a compact add-on board equipped with a microphone accompanied by a suitable amplifier. This board features the SPQ0410HR5H-B, a slim ultra-mini SiSonic™ microphone specification with Maximum RF protection and ultra-narrow design from Knowles. The microphone has an omnidirectional directivity, ultra-stable performance, and works in a 100Hz to 10KHz frequency range. It features MaxRF protection that prevents RF noise in traces from getting into the mic output. This Click board™ makes the perfect solution for the development of cell phones, smartphones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where excellent wideband audio performance and RF immunity are required.
Mic 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.

How does it work?
Mic Click is based on the SPQ0410HRSH-B, a slim ultra-mini SiSonic™ microphone specification with maximum RF protection and ultra-narrow design from Knowles. It is a MEMS microphone and consists of an acoustic sensor, a low noise input buffer, and an output amplifier. It is a very reliable microphone, resistant to mechanical shocks, vibrations, thermal shocks, low and high temperatures, ESD-HBM, and more. It is not resistant to high pressure and vacuum. The microphone is top-port oriented and has a typical sensitivity of -42dB at 94dB SPL, with a 59dB signal-to-noise ratio.
Mic Click uses an analog OUT pin of the mikroBUS™ socket to communicate with the host MCU. The analog output from the microphone to the OUT pin goes through the MCP6022, a rail-to-rail input/output 10MHz Op Amp from Microchip. This operational amplifier has a wide bandwidth, low noise, low input offset voltage, and low distortion and amplifies the microphone’s output with high performance.
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. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
