mikro-bus

Vendor: Generic or vendor-independent

Description

GPIO pins exposed on Mikro BUS headers.

The Mikro BUS layout provides two headers, aligned on the opposite
edges of the board.

This binding provides a nexus mapping for 10 pins, left side pins are
numbered 0 - 5 (AN - MOSI), the right side pins are numbered 6 - 10
(PWM - SDA). The bottom 2 pins on each side are used for input voltage
and ground, they are not mapped in the nexus.

                       Analog - AN     PWM - PWM output
                        Reset - RST    INT - Hardware Interrupt
              SPI Chip Select - CS      RX - UART Receive
                    SPI Clock - SCK     TX - UART Transmit
SPI Master Input Slave Output - MISO   SCL - I2C Clock
SPI Master Output Slave Input - MOSI   SDA - I2C Data
               VCC-3.3V power - +3.3V  +5V - VCC-5V power
             Reference Ground - GND    GND - Reference Ground

Board's silkscreen may vary depending you board, but coherent with
the description above as it's according to the standard's specification.
