About Connection Standards
Most accessory boards are designed to a specific standard, allowing them to be easily connected to development hardware (Development Systems / Ready-Start Systems / PLC Systems).

Note however that this does not mean that they can only be used with hardware featuring the relevant standard - they can of course also all be used with any hardware by manually making the connections to them. The connection standard simply makes things easier when compatible hardware is available.

The three different groups which accessory boards can be classified into, based on the connection standard they employ, are:
General (No Standard)

This type has no connection standard. Connections are simply made by soldering wires/pins onto the pads provided.

Any of the other types of connection standards (IDC10 / mikroBus) can obviously also be used in this way.










Example:

A MAX3232 accessory board, connected to a breadboard.
IDC10 Standard

This type makes use of the IDC10 connection standard, which exposes the 8 pins of a microcontroller's "port", as well as power and ground.

IDC10 Headers are found on MikroElektronika development systems, ready-start systems and PLC systems.





An adapter is available for connecting IDC10 accessory boards to mikroBus sockets.




Example:

A bipolar stepper motor driver accessory board, connected to an EasyPIC7.
mikroBus ("click") Standard

This type makes use of the mikroBus standard, which exposes specific pins for SPI, I2C, UART, etc.

mikroBus sockets are found on newer MikroElektronika development systems, as well as our Breeze boards and the Clicker boards.







Example:
A mikroBus WiFi PLUS click accessory board, connected to a Breeze board.

*Prices exclude VAT and may be subject to the Rand/Dollar exchange rate / change without notice. Please see the store for more information on pricing. Where a board is available in multiple different types, the price indicated is that of the least-expensive type.
