 /* 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
 *  - 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)
