-/* Board Configuration:
+/* Board Peripheral Assignment
+ * 
+ * RS232/Power connector:
  *  - USART1, is the default bootloader and console
+ * 
+ * Sensor Connector:
+ *  Digital:
+ *  - GPIOs: PB10, PB11 (or even TIM2 CH3 and CH4)
+ *  - USART3
+ *  - I2C2
+ *  Analog:
+ *  - ADC1
+ *  Supporting Analog Circuitry (not seen outside)
+ *  - RefTap (TIM3_CH3)
+ *  - Power PWM Out (TIM8_CH1 / TIM3_CH1)
+ *  - Filtered Out (TIM3_CH4)
+ *    (TIM8 could run at lower frequency, while TIM3 must run at highest possible)
+ *  - Gain selection muxed with SDcard I/Os.
+ * 
+ * Radio connector:
+ *  - UART3 / UART4
+ *  - SPI2
+ *  - I2C1 (remapped pins vs. Expansion connector)
+ *  - CAN
+ *  - TIM4 CH[3:4]
+ * 
+ * Expansion connector:
+ *  - WakeUp Pin
+ *  - System Wide Reset
  *  - SPI1 is wired to expansion port
- *  - SPI2 is used for radio module
+ *  - I2C1
+ *  - USART2 [Rx, Tx, CTS, RTS]
+ *  - DAC [0:1]
+ *  - ADC2 on pins [0:7]
+ *  - TIM2 Channels [1:4]
+ *  - TIM5 Channels [1:4]
+ * 
+ * Onboard Components:
  *  - SPI3 has direct connection with FRAM
  *  - SDCard, conencts the microSD and shares the control lines with Sensor Interface
  *    to select Amplifier Gain
- *  - ...
+ *  - ADC3 is used also for power management (can be shared with ADC1 on sensor connector
+ *    if not used)
