After 10 years in development of accessory board, we came up with the smallest number of most commonly used pins.
Two 8-pin female sockets are all it takes to build the host connector. And then you are ready to use dozens of boards.
Some boards use 3.3V and some 5V. With mikroBUS™, power supply is not an issue anymore. Dual power supply is an essential feature.
mikroBUS™ connector has 100mil pin spacing, and 900mil distance between connectors, which makes it a perfect match for breadboards.
As we in mikroElektronika see it, plug-and-play devices with minimum settings are the future in embedded world. This is why our engineers have come up with a simple but brilliant pinout with lines that most of today’s accessory boards require, which almost completely eliminates the need of additional hardware settings. We called this new standard the mikroBUS™.
Each mikroBUS™ host connector consists of two 1x8 female headers containing pins that are most likely to be used in the target accessory board. There are three groups of communication pins: SPI, UART and I2C communication. There are also single pins for PWM, Interrupt, Analog input, Reset and Chip Select. Pinout contains two power groups: +5V and GND on one header and +3.3V and GND on the other 1x8 header. mikroBUS™ host connector perfecty fits into standard breadboards.
mikroBUS™ is not made to be only a part of our development boards. You can freely place mikroBUS™ host connectors in your final PCB designs, as long as you clearly mark them on the silkscreen with mikroBUS™ footprint specifications:
You are allowed to produce your own mikroBUS™ compatible board, as long as you place mikroBUS™ logo on the board silkscreen. Also, you are not allowed to call it “Click board” because “Click” is the trademark of mikroElektronika. You are also allowed to make commercial version of your board. It would be nice to hear about it, so send us an E-mail to firstname.lastname@example.org
mikroElektronika’s portfolio of almost 200 accessory boards is now enriched by an additional set of mikroBUS™ compatible Click boards™. It is our intention to provide the community with as much of these boards as possible, so you will be able to expand your designs with additional functionality and minimim hardware configuration. Just plug and play.
