GPIOs and Pin Assignment and Functions of DA14531 DK PRO
All signals of the DA14531 PRO-DBs are provided to DA14531 PRO-MB. The signal names are
specific for the PRO-MB and do not have the same names as the signals of the PRO-DBs. The
reason is that the PRO-MB can be used for both DA14531 SoC and DA1458x family of SoCs,
whereas DA14531 SoC has fewer pins than DA1458x SoCs.
Please note that signals of DA14531 SoC (P0_0 to P0_10) are provided to ports 2 and 3 of the PRO-
MB (P2_0 to P2_9, P3_0, and P3_1). So, on the breakout header
J2
of the PRO-MB, the pins of
DA14531:
●
P0_0 to P0_11 are mapped to P2_x, P3_0 and P3_1 for FCGQFN24
●
P0_0 to P0_5 are mapped to P2_0 to P2_5 for WLCSP17

Due to the low GPIO count, function multiplexing is applied. Every function of the DA14531 DK PRO
is practically dependent on the PRO-MB GPIO configuration, as the configuration of the PRO-DB
requires soldering and de-soldering of resistors.
The PRO-MB configuration is realized with jumpers or cables. J1 on the PRO-MB is the main
configuration header (
).
PRO-DB configuration is also feasible. Please refer to
