 ====== Expansion Connectors ======
 The Odroid-c1 povides one 40-pin dual row expansion header "**J2**".
-The location and pinout of these connectors is illustrated blew.\\ All signals on expansion headers are 3.3V except Analog input signal.
+The location and pinout of these connectors is illustrated blew.\\ All signals on expansion headers are 3.3V except Analog input signal(1.8V).\\
+Built-in pull-up/down resistor value is 60Kohm in the GPIOs.
