3.1.1
Features of DA14531 PRO-DB
●
Embedded printed antenna
●
RF port output (connector not included)
●
DA14531 power mode configuration switch (only for backwards compatibility with DA1458x DK
PRO motherboard)
●
Current measurement port to connect external measurement equipment
●
Onboard JTAG connector
●
Support for coin cell battery (battery holder not included)
3.1.2
Features of DA14531 PRO-MB
●
A slot to connect a DA14531 PRO-DB which hosts either the DA14531-FCGQFN24 or the
DA14531-WLCSP17 SoC
●
All the power wiring configurations to allow DA14531 PRO-MB to operate in either Buck, Boost,
or Bypass mode
●
Dedicated hardware for current measurement that enables Dialog
’s SmartSnippets Toolbox
power profiler software as well as any externally connected power measurement device to profile
the power consumption of the system
●
Single USB port to provide power and data interfacing to a PC (USB1)
●
Onboard JTAG debugger
●
Virtual 4-wire UART port
●
The DA14531 RESET line is controlled over JTAG by using an onboard push button
●
Onboard 2-Mbit SPI data Flash (MX25R2035)
●
Multiple voltage options (1.1 V, 1.8 V, 3.0 V, and 3.3V) to supply the DA14531 SoC on the
DA14531 PRO-DB
●
Support for coin cell battery (battery holder not included)
●
User LEDs and push buttons (to be used with a DA14531 FCGQFN24 PRO-DB)
●
Voltage translation for the JTAG and UART signals that allows the current leakage during system
operation to be eliminated
