@@ -9,5 +9,8 @@ Currently the Arduino breakout board is supported by libmraa.
 The Edison used with the Arduino board has the following limitations
 in libmraa:
 
+- i2c is exposed on i2c-6, therfore you must use bus 6 and not bus 0
 - PWM avaible on default swizzler postions. (3,5,6,9)
 - SPI exposed is also used for the ADC. Try not to use your own CS.
+- ADC kernel module will return 12bit number but the ADC itself only has an
+  accuracy of 10bits. This ADC is only included on the arduino board.
