Board setup
To set up the board:
1
Ensure that a jumper on JP3 is connected (position 1-2); it sends the RESET
signal to the SPWF04A1 module on the board.
2
Ensure that jumpers on JP6, JP7, JP8, JP9 are connected (position 1-2); they link
UART module signals to STM32 Nucleo UART peripheral.
If the SPI interface is preferred, ensure that jumpers JP6, JP7, JP8, JP9 (position
2-3) are connected.
3
Ensure that jumpers on JP10, JP11, JP12, JP13 are connected (for position and
configuration, refer to
Figure 3: "UART default jumper configuration"
and MicroPython 0
Ω resistors are unsoldered.
These jumpers are needed to properly drive UART module signals to the STM32
Nucleo.
Figure 3: UART default jumper configuration
If the SPI interface is preferred, ensure that jumpers on JP10, JP11, JP12, JP13
are connected (for position and configuration, refer to
Figure 4: "SPI jumper
configuration"
and MicroPython 0 Ω resistors are unsoldered. Moreover, JP5 must
be closed.
Figure 4: SPI jumper configuration
If the MicroPython feature is preferred, remove jumpers on JP10, JP11, JP12,
JP13 (refer to the following table for a full 0 Ω resistor configuration).
