4. The DA14585/586 Hardware

The DA14585/586 Pro Development Kit DA14585/586 ProDev Kit consists of a motherboard (MB-PRO) and a DA14585 daughterboard featuring the DA14585/586 SoC of the desired package, WLCSP34 or QFN40.

4.1. The ProDev Kit Motherboard

Figure 1 illustrates the physical layout of the ProDev Kit motherboard Rev C. The Figure 5 shows The DA14585/586 ProDK combined with the the DA14585 daughterboard.

The ProDev Kit Motherboard provides the necessary hardware to enable:

• full digital connectivity with external hardware using UART, SPI, GPIO, and I²C

• USB based debugging capabilities using the SEGGER J-Link on-board debugger

• USB based UART communication with the host PC using a Future Technology Devices International (FTDI) chipset which converts UART to USB signal.

Note

• DA1458x share the same ProDev Kit motherboard (DA14580 DEVKT).

Note

The schematic diagrams, BOM, and Gerber files are illustrated in detail in the Development Kit Documentation.

4.5. Connecting the ProDev Kit to the host PC

The ProDev Kit motherboard includes FTDI chipset U1 FT2232HL which allow easy communication with the development host over USB. The FT2232HL implements the USB to UART function and ensure the connectivity of PC to the DA14585/586 SoC UART port and to current sense circuitry through SPI connection with ADC U4.

The chip is supplied with a 3.3V from U13. A 12MHz crystal Y1 is required for the chip operation.

The ProDev Kit motherboard also includes an embedded J-Link debugger U6 SAM3U2CA. The chip is supplied with a 3.3V from U13 which is enabled by PWR_ENABLE signal.

Before connecting the ProDev Kit to the host PC, make sure that the motherboard and the desired daughterboard module are properly connected.

A choice can be made between 3.3 V (via USB: J11 1-2) or VDD (a coin cell: J11 2-3). No battery is needed when running via the mini-USB cable.

The ProDK Development Kit is connected to the host PC over the connector marked as USB1, as shown in reference 6 in Figure 6 using a standard mini-USB

Figure 6 ProDK Development Kit connections

Note

• The ProDev Kit is connected to the host PC over the connector marked as USB (J12), as shown in Figure 5 using a standard mini-USB cable.

• When mounting a battery on the daughterboard, Jumper J11 should be fitted on 2-3 position.

• For proper battery functionality, a small modification should be made. See the workaround in Appendix C.
