I/O Connector

Description

Board use RJ45 connector to provide connection to follow function

  • Power line +5V, GND
  • Serial port Rx, Tx (digital line D0 and D1)
  • TWI interface SDA, SCL (depends of version Uno Analogue Line A4,A5, Leonardo Digital Line D2, D3)
  • Analogue Line A6,A7 (use from special models or may be reconected to other Analogue Line)
  • Digital Line D8,D9,D4,D6
