module.
FAN_TACHOIN: External FAN Tachometer Input. +3.3V_RUN voltage signal
-up resistor, directly managed by ST Microelectronics STM32F100R6H6
microcontroller
FAN_PWMOUT: PWM output for FAN speed management, +3.3V_RUN voltage signal. It is managed by
.
SPKR: Speaker output, +3.3V_RUN voltage signal, directly managed by
.
THRM#: Thermal Alarm Input. Active Low,
-up resistor, directly managed by ST Microelectronics STM32F100R6H6
microcontroller. This input gives the possibility, to carrier boa
throttling.
THRMTRIP#: Thermal Trip Output. Active Low,
-up resistor, directly managed by ST Microelectronics STM32F100R6H6
microcontroller. Thermal Trip indicates an overheating condition of the processor. When goes active, the system immediately transitions to the S5 State (Soft Off).

Manufacturing signals
According to Qseven
®
Standard specifications, rel. 2.1, on pin designed as MFG_NCx ( 207÷210) are carried through a multiplexer NXP i.MX8M Internal UART1
signals for firmware and boot loader implementations. Pin 204 (MFG_NC4) drives the selection pin of the multiplexer to enable debug UART1. This pin must be floated
to enable debug UART
Pin 207 (MFG_NC0) signal
Pin 208 (MFG_NC2) signal
Pin 209 (MFG_NC1) signal
Pin 210 (MFG_NC3) signal
UART1_RTS
UART1_RXD
UART1_TXD
UART1_CTS
The UART interface available on MFG_NCx pins is reserved only for the manufacturing phase; it must not be used by the customer.
It is not possible at all to use these pins to trace the software (for debug purposes)
