CAN_T
This jumper, when is closed, CAN termination is enabled, and when is opened, CAN
termination is disabled.
Default state is opened.
D10/D4
This jumper, when is in position D10, UEXT pin 10 (UEXT_#CS) is connected to
STM32F103RBT6 pin 20 (PA4/SPI1_NSS/USART2_CK/ADC4) – signal D10, and
when is in position D4, UEXT pin 10 (UEXT_#CS) is connected to STM32F103RBT6
pin 57 (PB5/I2C1_SMBAI/TIM3_CH2/SPI1_MOSI) – signal D4. Note that P10_E's
effect also is affected by D10/D4.
Default state is in position D4.
P10_E:
When closed the board provides 3.3V to the UEXT_CCS – UEXT pin.
Default state is closed.
3V3A/5V
This is a new jumper introduced in hardware revision F of the board. It changes the
voltage provided to pin #3 of the power shield connector from the default 5V to 3.3VA.
IMPORTANT! Hardware revision F introduced changes to the POWER connector of the
Arduino shield. Now there are 5V available at pin #3 of the POWER connector by default!
It was 3.3V in older revisions. Be careful if you use 3.3V shields! You can revert the
voltage of the pin back to 3.3V if you change the position of the 3V3A/5V jumper!
Default state is in position 5V.
