A101-DEV is the development board for the A101 Universal UWB Real-Time Positioning Anchor. It offers the full functionality of the A101 anchor.
In addition to the A101 anchor design, it breaks out all ESP32-S3 pins and other important test points. You can use these pins and test points to extend functionality and monitor system operation.
The device is highly flexible: it can serve as a synchronized transmitter in downlink TDOA mode or as a receiving endpoint in uplink TDOA mode. In downlink mode, the A101 can run standalone without a network, which greatly reduces dependence on network infrastructure.
Key features
- Multi-mode support: Compatible with uplink and downlink TDOA positioning modes to suit different deployment models.
- High-precision clock sync: Proprietary clock synchronization keeps inter-anchor time error below 0.6 ns for stable centimeter-level positioning.
- Flexible networking: Built-in Wi-Fi; in downlink TDOA mode, operation without a network is supported.
- Power and deployment: Standard USB Type-C 5 V input, compatible with common 5 V / 1 A adapters for easier cabling.
- Smart management: USB HID for local configuration and remote parameter tuning over the network; DHCP or static IP.
- Security and compatibility: Unique EUI-64 ID, PAN ID filtering; conforms to IEEE 802.15.4-2011.
- RF tuning: Configurable preamble length, PRF, PAC, and other UWB parameters for challenging multipath environments.
- Maintainability: Over-the-air (OTA) firmware updates; multi-function status LED with adjustable brightness.
