9. DA1468x – The hardware

The Pro Development Kit (ProDK) consists of a main board (MB-PRO) and a daughterboard featuring DA1468x SoC of the desired package (AQFN60 or WLCSP).

9.1. The ProDK mainboard

Figure 1 illustrates the physical layout of the ProDK. The two (2) daughter boards containing DA1468x devices (AQFN60 as well as WLCSP packages) are shown in Figure 2.

The ProDK main board provides all necessary hardware to enable:

  • Full functional verification of the DA1468x family of products with the ability to take precise power measurements by isolating the DA1468x device.
  • Full digital connectivity with external hardware using UART, SPI, I2C, quadrature encoder or GPIOs.
  • 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.

9.2. The ProDK daughter-boards

The ProDK mainboard can be combined with one of the two daughter-boards shown in Figure 2. These daughter boards allow evaluation of the two different package options for the DA1468x devices. The daughter-boards each have a switch to select the power supply for the device:

  • USB port/charger input (USB1/CHG or USB2/DBG) which is marked VBAT or
  • Coin cell battery which is marked VBAT. The coin cell battery can be either rechargeable or non-rechargeable. To use a non-rechargeable coin cell battery the user must make sure that the battery charger code is disabled in the project.

Both daughter-boards are supported in the SmartSnippets™ DA1468x SDK. More details on how to set the build configuration for each board can be found in [Ref_03].

9.3. Connecting the ProDK to the host PC

The ProDK Development Kit allows functional verification of the DA1468x family of devices. It supports connecting external hardware by exporting DA1468x pins to standard headers and enables the user to do precise power measurements through the integrated power measurements circuitry. Additionally, the ProDK mainboard includes an embedded J-Link debugger and an FTDI chipset which allow easy communication with the development host over USB.

The ProDK Development Kit is connected to the host PC over the connector marked as USB2(DBG), as shown in Figure 3 using a standard mini-USB cable. Before connecting the ProDK Development Kit to the host PC, make sure that the mainboard and the desired daughterboard module are properly connected and that the power switch on the daughterboard is in the VBAT position to select USB from motherboard.
