Current 4 Click is a compact add-on board that provides a precise and accurate current sensing solution. This board features the INA250, a bidirectional, zero-drift current-shunt monitor from Texas Instruments. This voltage-output, current-sensing amplifier measures the voltage developed across the internal current-sensing resistor when current passes through it. Also, by selecting the reference voltage, the INA250 allows users to measure both unidirectional and bidirectional currents through the current-sensing resistor. This Click board™ delivers higher performance to applications such as test and measurement, load monitoring and power supplies, automotive, and many more.
Current 4 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.

GainAMP Click is a compact add-on board that can amplify signals on any of the two inverting input channels. This board features the LTC6912, a dual programmable gain amplifier with a serial digital interface from Analog Devices. The LTC6912 has independent gain control on both channels, and you can set one of the 0, 1, 2, 5, 10, 20, 50, and 100V/V voltage gains with channel-to-channel gain matching of 0.1dB max. In addition, the wired-OR outputs are possible (2:1 analog MUX function). This Click board™ makes the perfect solution for the development of data acquisition systems, dynamic gain changing, automatic ranging circuits, automatic gain control, and more.
GainAMP 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.

AudioAmp 4 click is a low-power audio amplifier with a digital volume control. It is equipped with the LM4860, an audio amplifier IC capable of delivering up to 1W of continuous power to an 8 Ω load. It has a very low total harmonic distortion (THD) of less than 1% over the entire audio spectrum, which makes it perfectly suited for small boom-boxes, PC speakers, and similar low-power sound reinforcing devices that can be powered by batteries. A high integration level of the LM4860 IC allows an additional circuit for digital signal attenuation to be used, offering 8 different volume levels, selectable over 3 GPIO pins of the mikroBUS™.
AudioAmp 4 click is supported by the mikroSDK compliant library, which includes functions that simplify software development. The Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ slot.

Audio Amp 2 Click is a highly efficient class D audio amplifier, using the TDA7491, a dual BTL class-D audio amplifier IC, capable of delivering up to 20W to 8Ω load. This amplifier IC features high-efficiency output stage drivers and clever design, allowing it to deliver a reasonably high power to the connected speakers, using only GND polygon on the PCB for heat dissipation. In the BTL topology, the output DC blocking capacitors are not required. This allows for simpler design and lower power losses, especially with no input signal. The TDA7491 amplifier IC is equipped with a set of protection features, that allow reliable operation.
