Terminal Click Board™

Product Code: MIKROE-3745

The Terminal Click Board™ can be especially interesting for the development systems that are equipped with mikroBUS™ slots only, or a small number of GPIO pins available, such as the Clicker family of development systems. Using Terminal click on such a system will greatly improve its usability, and yet it will remain small, compact and manageable. Thanks to the standard-pitch (2.54mm) header, it is easy to connect a wire jumper, a probe of an oscilloscope for example, or maybe some additional electronic circuit. That way, Terminal click makes it easy to monitor signals in real-time, while the click board is present in the system. How Does The Terminal Click Board™ Work? The Terminal Click Board™ consists of a high-quality PCB that can be connected to the mikroBUS™ as any other click board. On the top of the Terminal click, a 2x8 pin header is placed. Each of the header pins is corresponding to a pin on the mikroBUS™ being used. These are simply wired in parallel. Thanks to the stacking headers, the connection with the Click Board™ remain firm and stable.

Besides, having this kind of stacking topology, allows for easy pin access and manipulation of the stacked click boards™, retaining a perfect connection quality at all times. When there's a need to attach external equipment to the development system, the desired mikroBUS™ socket can be populated with Terminal click, allowing even more connections. This makes the stacking capacity almost unlimited. However, attention should be paid not to make the lines attached to the mikroBUS™ too long. In situations like this, the frequency of the communication might need to be stepped down a bit, in order to compensate for the longer mikroBUS™ signal lines. Lines of the mikroBUS™ to which Terminal click is attached, are shared through the top 16-pin header, which mirrors pins of the connected mikroBUS™. Therefore, care should be taken when working with the Terminal click and connecting an external device to it, because the same pins on the mikroBUS™ are shared, either for the communication (SPI, UART, I2C) or for some other purpose (RST, INT, or other pins used as GPIO). Since all the stacked click boards™ share the same power rails, a Terminal click also shares the power rails, which makes it compatible with any click board™ and development systems. Click board™ product range The union of Terminal click with the other click boards™ allows you to reach an unlimited number of possibilities when it comes to combining different functionalities and adding external connectivity. You just need to choose the ones you want from our ever-growing range: environmental sensors, LEDs, speech recognition, heart rate sensors, motor control, GSM, GPS, WiFi, analogue to digital converters, movement sensors. More than 1000 Click Boards™ that can be stacked and integrated in a simple and convenient way are at your disposal.
