AI-Thinker® Wideband Indoor Positioning Module Close-Range High-Precision Distance Measurement NodeMCU-BU01 Development

Introduction UWB technology is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz It does not use a sinusoidal carrier but uses nanosecond level non sinusoidal narrow pulses to transmit data Therefore it occupies a large frequency spectrum Although it uses wireless communication its data transmission rate can reach hundreds of megabits per second Using UWB technology can transmit signals over a very wide bandwidth BU01 is an ultra wideband UWB transceiver module based on Decawave s DW1000 design BU01 integrates antenna RF circuit power management and clock circuit BU01 can be used in two way ranging or TDOA positioning systems with positioning accuracy up to 10 cm and supporting data rates up to 6 8 Mbps Feature Simple integration no RF design requiredUse RTLS infrastructure to expand the communication rangeSupport high label densityComply with IEEE 802 15 4 2011 UWB standardSupport 4 channels from 3 5 GHz to 6 5 GHzProgrammable transmit powerPower supply 2 8 V to 3 6 VPower consumption in sleep mode1mASupport two way ranging and TDOASupport SPI interfaceData rate 110 kbps 850 kbps 6 8 MbpsModel NameNodeMCU BU01Dimensions35 55 5 ±0 2 W H mmPackageDIP 40AntennaPCB antennaFrequency3 5GHz to 6 5GHzInterfaceThe all 10 of PWM I2C GPI0 MCUOperating temperature 40°C 85°CStorage environment 40 °C 125 °C B1590 RHPower supply5V or 3 3VPower consumptionDevelopment board 160 mA with MCU sensors Documents Nodemcu
