TERMINAL CLICK
PID: MIKROE-3745
Weight: 21 g
Terminal click is a mikroBUS™ socket expansion board, which provides an easy and elegant
solution for adding the external connection capability to the click board™, plugged on a
mikroBUS™. Featuring stacking headers makes it easy way for expanding the connectivity of
the development system with the mikroBUS™, while keeping the bus free to use with any click
board™.
Terminal 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.
Terminal click can be especially interesting for the development systems that are equipped with
mikroBUS™ slots only, or small number of GPIO pins available, such as the Clicker family of
development systems. Using Terminal click on such system will greatly improve its usability,
and yet it will remain small, compact and manageable. Thanks to 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 monitor signals in realtime, while the click board is present in the system.
HOW DOES IT WORK?
Terminal click 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™ remains 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, a 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, analog to digital converters, movement sensors.
More than 700 click boards™ that can be stacked and integrated in a simple and convenient
way are at your disposal.
