4.1 Introduction
EVB-ANT-1 is a versatile application board for evaluating a system setup, using the ANT-B10 board,
or other antenna boards. The board can be used as:
•
an anchor point passing raw or processed angle events from the antenna board to a server
•
a positioning engine server
•
a preprocessor applying filtering or other reformatting of the angle events from the antenna board
before passing them on to the network
•
a host board for evaluating other antenna boards
EVB-ANT-1 has a connector and mechanical dimensions that make it suitable for mounting an
ANT-Bxx board. The board is protected with an enclosed plexiglass, as shown in

The main components of the EVB-ANT-1 include:
•
MAYA-W1 Wi-Fi module for Wi-Fi and Bluetooth connectivity
•
Arm-Cortex M7 MCU (NXP MIMXRT1060 family)
•
Ethernet controller for ethernet connectivity
•
Power over Ethernet (PoE) controller for powering the board using an Ethernet cable
•
NINA-B411-40B Bluetooth module running u-connectLocate software for evaluating external
antenna boards
•
Quad UART-to-USB converter providing access to the serial interfaces of the MCU, ANT-B10, and
the onboard NINA-B4 module
4.3 Main EVB-ANT-1 use cases
4.3.1 Anchor point
In this use case, the EVB-ANT-1 primarily supports ANT-Bxx antenna boards and routes direction
finding data to a position engine. For this purpose, the microcontroller must communicate with the
ANT-Bxx antenna board Bluetooth module using UART (or SPI) through the ANT-Bxx connector.
