Known Issues

Refer to the Schematics for all components references.

• USART 0

  • U0_CTS (PA.4) must be connected to U9.9

  • U0_RTS (PA.3) must be connected to U9.10

  • U9.8 (R2IN) must be connected to J8.7

  • U9.7 (T2OUT) must be connected to J8.8

• USART 1

  • U10.11 (DTR1) must be connected to J9.6

  • U10.8 (DSR1) must be connected to J9.4

• LEDS

  • LED 5/Green is connected to GPIO PB.19 and not to PB.20

  • LED 5/Red is connected to GPIO PB.20 and not to PB.19

  • LED 6/Green is connected to GPIO PB.21 and not to PB.22

  • LED 6/Red is connected to GPIO PB.22 and not to PB.21

• SPI

  • Wrong Silkscreen: MISO and SCK are swapped

• ADC

  • ADVREF pin must be connected to 3.3V

• SENSORS

  • R62 and R137: The resistance value of NTC Thermistor 100kΩ at 25℃ and 200kΩ resistor causes the ADC sample and hold module to not stabilize in the expected minimum time of 600ns
