+"""Pin definitions for Udoo x86 Ultra
+(should work for Ultra and Ultra II)
+
+There are 2 naming systems.  A Digital Pin system which includes
+the arduino chip (Leonardo or 101).  The Braswell #s start at 16 and
+is documented in the diagram and text for linux version later than 4.15 in:
+https://www.udoo.org/docs-x86II/Introduction/Introduction.html
+The other is based on the hardware manual:
+https://udoo.org/download/files/UDOO_X86/Doc/UDOO_X86II_MANUAL.pdf
+
+This will use the D system based on the diagram in the user guide
+
+i2c use i2c(board.I2C0_SCL, board_I2C0_SDA) or i2c(board.I2C1_SCL, board_I2C1_SDA)
+for the i2c(board.SCL, board.SCL) in the examples
+
+UART use pyserial not busio
