SpeakUp click
 
mikroBUS
SpeakUp click The SpeakUp click is a speaker dependent speech recognition accessory board, which also has the ability to run standalone (no external microcontroller needed). It can be programmed to recognize over 200 different voice commands, which the onboard STM32F415RG MCU can react to. It works by matching sounds with pre-recorded commands. The firmware is based on the DTW speech recognition alghoritm, which enables fast operation with instant recognition. Sound is received through an onboard microphone and then processed by a VS1053 IC with a built in stereo-audio codec. The SpeakUp comes with a dedicated software tool for easy configuration. The board is lined with 12 user programmable GPIOs for standalone functionality, and can also be connected to a mikroBUS host socket, with communcation via SPI, I2C or UART.

Noise click
 
mikroBUS
Noise click Noise click is a mikroBUS add-on board with noise detecting circuitry. It enables you to set a noise detection threshold for alarm systems, environmental monitoring or data logging. When the volume of ambient sound reaches the set threshold, an interrupt is triggered.

The most important parts of the circuit are the microphone, an RMS-to-DC converter, two dual rail-to-rail Input/Output 10 MHz operational amplifiers, and a 12-bit digital-to-analog converter (DAC).

The 12-bit DAC provides the reference voltage — the noise threshold — for the comparator. You set the exact level through the SPI interface. The threshold should be configured through trial and error (4096 discrete values to select from).

Beside SPI, EN and OUT pins provide additional functionality.

The board works on a 3.3V power supply.

AudioAmp click
 
mikroBUS
AudioAmp click AudioAmp click is a mikroBUS add-on board that functions as a mono audio amplifier. It is driven by a Texas Instruments LM48100Q-Q1 Boomer Mono, 1.3W Audio Power Amplifier IC.

AudioAmp click has one 3.5 mm input jack and next to it screw terminals for connecting output wires to a passive speaker. It has dual audio inputs that can be mixed/multiplexed to the device output. Each input path has its own independent, 32-step volume control. The mixer, volume control and device mode selection are controlled through the mikroBUS I2C interface.

Fault detection is another important feature of LM48100Q. It senses the load conditions, protecting the device during short circuit events, as well as detecting open circuit conditions.

AudioAmp click can work either on a 3.3V or a 5V power supply. There's an additional jumper for selecting the I2C address as well. The open-drain output fault flag. FAULT is routed through the default mikroBUS INT pin (0 indicates that a fault condition has occurred).
