 Serial Console
 ==============
 
-  To be provided
+  Two UART connections are available:
+
+    UART0 is available on J5 Debug Port.
+    UART2 is available on J11
+
+  By default, the serial console will be provided on UART0 in all of these
+  configurations.
 
 LEDs
 ====
 
-  To be provided
+  The pcDuino v1 has four green LEDs.  Two are tied to ground and, hence,
+  illuminated by driving the output pins to a high value:
+
+    1. LED1 SPI0_CLK  SPI0_CLK/UART5_RX/EINT23/PI11
+    2. LED5 IPSOUT    From the PMU (not controllable by software)
+
+  And two are pull high and, hence, illuminated by grounding the output:
+
+    3. LED3 RX_LED    LCD1_D16/ATAD12/KP_IN6/SMC_DET/EINT16/CSI1_D16/PH16
+    4. LED4 TX_LED    LCD1_D15/ATAD11/KP_IN5/SMC_VPPPP/EINT15/CSI1_D15/PH15
 
 Buttons
 =======
 
-  To be provided
+  There are a total of five switches on-board.  All pulled high and, hence,
+  will be sensed as low when closed.
+
+    SW1 Reset     (not available to software)
+    SW2 UBOOT     UBOOT_SEL (?)
+    SW3 Key_Back  LCD1_D17/ATAD13/KP_IN7/SMC_VCCEN/EINT17/CSI1_D17/PH17
+    SW4 Key_Home  LCD1_D18/ATAD14/KP_OUT0/SMC_SLK/EINT18/CSI1_D18/PH18
+    SW5 Key_Menu  LCD1_D19/ATAD15/KP_OUT1/SMC_SDA/EINT19/CSI1_D19/PH19
