Home / Products / CoreHW AoA Locator 2

The CHW1010-LOCN2-1.0 locator is an evaluation kit locator for developing indoor location systems using Bluetooth^® AoA technology. It features the CoreHW ANT1 AoA antenna array board, which includes 8 dual linear polarized patch antennas and a CoreHW CHW1010 SP16T antenna switch for controlling and sampling RF signals.

The CoreHW IPS Main Board, powered by the Nordic Semiconductor nRF52833 SoC, manages the antenna switch and performs I/Q-sampling of packets from tags. Additionally, the STM32 MCU from ST Microelectronics runs CoreHW’s proprietary algorithm to estimate 2D angles (Azimuth & Elevation) for tags. These estimates can be transmitted for further processing via Ethernet, USB, UART, or SPI interfaces.

CoreHW provides a complete AoA evaluation kit, including firmware and Windows software with a GUI. This system, featuring four locators, is ideal for lab tests and initial evaluations in real-world scenarios.
