/* 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)
