Solder drop configurations
Solder drops allow the following configurations of the X-NUCLEO-53L1A2 expansion board:
•
If the developer wants to make an application with several expansion boards stacked and there is:
–
conflict with the microcontroller port allocation, the GPIO1 can be output on the CN8/A4 (U17 fitted) of
the Arduino connector. The default configuration is that GPIO1 is output on the CN8/A2 (U14 fitted) of
the Arduino connector.
–
conflict on the I2C addresses, the addresses of the STMPE1600 can be modified (the default
addresses are A2, A1, A0, 000, and 001).
•
If the developer wants to connect breakout boards (see
Figure 5. Interrupt configurations
) to the X-
NUCLEO-53L1A2 expansion board:
–
the VL53L1 interrupt of the left breakout board can be output on the CN5/D9 (U10 fitted) or CN5/D8
(U11 fitted) of the Arduino connector. By default, the U10 and U11 are not fitted.
–
the VL53L1 interrupt of the right breakout board can be output on the CN9/D4 (U15 fitted) or CN9/D2
(U18 fitted) of the Arduino connector. By default, the U15 and U18 are not fitted.
–
the VL53L1 interrupt of the left and right breakout boards, GPIO1_L and GPIO1_R, can be shared with
the VL53L1 interrupt on the main board, GPIO1, by fitting U7 and U8 solder drops. By default U7 and
U8 are not fitted.
