Page 2: Document Information
Early Production Information ☞ u-connectLocate is renamed to u-locateEmbed. ☞ The ANT-B10 antenna board hosts the NINA-B411-40B, which is a specialized variant of the NINA-B411. This module variant runs the u-locateEmbed software supporting the u-blox angle-of-arrival (AoA) algorithm. ☞ For information about the related hardware, software, and status of listed product types, see also the ANT-B10 data sheet [1]. -

Page 5: Functional Description
The angles are calculated by the u-locateEmbed software running on the embedded MCU in the module. The angles are delivered over the UART port of the ANT-B10. Support for USB and SPI interfaces is planned for future u-locateEmbed software versions. -
Page 6: Software Information
ANT-B10 - System integration manual An overview of the main building blocks of ANT-B10 is shown in Figure 2, where it can be seen how an RF antenna switch is used to select input from the different antennas on the board. The switch is controlled by five GPIO signals. -

Page 8: Connection To A Host Using Usb-To-Uart Adapter
1.27 mm pitch, 20-pin, female adapter should be mounted on the pin-header of the ANT-B10 board. The adapter is used to connect the cable harness between the ANT-B10 pin header and the USB-to- Serial adapter. As ANT-B10 is powered by the USB-to-Serial Adapter, there is no need for external power supply. -
Page 9: Native Usb
Native USB is planned for future release but is not currently supported. 2.5 SPI ANT-B10 supports a Serial Peripheral Interface with serial clock frequencies up to 8 MHz. The interface is accessible through the 20-pin header connector. The characteristics of the SPI interface include: •... - Page 10 ANT-B10 - System integration manual Table 2 describes the pin definitions and system control signals used by NINA-411 and ANT-B10.

Page 11: Design-In
As a full antenna board that includes a single pin header as its sole physical interface, the design-in of the ANT-B10 board from an electrical point of view is quite simple. The user simply must feature a matching pin header on their application board where ANT-B10 will be connected. -
