BU04-Kit is an evaluation platform, not a turnkey location system. The added Robosap route identifies the DW3000 + STM32F103 model in stock and advertises GST invoices, but the seller is Listed — unverified and publishes no warranty term. Confirm dual-antenna arrangement, included cables, firmware/examples, final tax-inclusive price, invoice and warranty before payment; accurate PDOA/TDOA still needs calibrated synchronized devices.
UWB does not use IN865. Before operating in India, confirm permitted UWB channels, emission limits, antennas and approval obligations for the exact development board and finished device.
