Page 6: General Description
The Basic development kit is based on the DA1468x SoC in an aQFN60 package. The highlighted sections of the system are: 1. DA1468x Dialog Semiconductor processor and interfaces. 2. QSPI Flash memory (U9 or U2): only for DA14681 devices. 3. USB port (USB2) with mini-USB connector. This is the evaluation, power supply and debugging port of the development kit. -

Page 14: Qspi Data Flash Memory (U9 Or U2)
Termination resistors are placed between the processor and Flash memory. These resistors are not required, but they are placed there to mitigate any signal integrity issues when additional loads are present (e.g. logic analyser probes on the breakout headers).
