Components of Basic development kit:
•
U1
: Dialog BLE SoC, DA14585 or DA14586 in QFN40 package. DCDC converter of SoC is
configured in Buck mode. Two crystals are used, 16MHz and 32.768 KHz.
•
U5
or
U7
: SPI data flash, MX25R2035. Two packages are available, U5
–WSON
MX25R2035FM1IH0 and U7-SOIC8 - MX25R2035FZUIL0
– (default). For DA14586, flash
memory is not mounted.
•
U4
: MCU where Segger license is applied. UART and JTAG connectivity is provided to
DA14585/586 SoC
•
SW1
: Reset push button. By pressing the button, used can hardware reset the processor
•
J4
: 28 pins header. Signal and power pins of DA14585/586 are provided. Also the interconnection
between BLE processor and Segger license MCU for JTAG and UART is done through jumpers.
•
J5
: 3 pins connector. DA14585/586 can be supplied by either 3.3V generated from on the
development kit or by coin cell battery applied on the bottom side of the development kit.
•
J9
: two pins header. It enables user LED. LED is driven from P1_0.
•
J10
: 10 pins header. It is used for monitoring DA14585/586 port 2 pins.
•
J11
: 10 pins header. Only P3_0 is provided on pin 1. Please notice that for DA14586, P3_0 is
not used.
Note: The schematic diagrams, BOM, and Gerber files are illustrated in detail in the
6.4
Connecting the Basic Kit to the host PC
The Basic Kit includes an embedded J-Link debugger which allow easy communication with the
development host over USB.
The DA14585/586 SoC is configured only in Buck mode on this development kit. A choice can be made
between 3.3 V (via USB: J5 1-2) or VDD (a coin cell: J5 2-3). No battery is needed when running via
the mini-USB cable.
Note: The basic Kit is connected to the host PC over the connector marked as USB (J3), as
shown in Figure 6 using a standard mini-USB cable.
