Both antennas are integrated into the 14x14x1.5mm LGA module. The module enables wireless communication with highly precise localisation, accurate to within 10 cm over a range of up to 50m. For applications with ranges of upwards of 50 meters, the ISP3010 can be used in conjunction with external optimised UWB antennas with the same precision, depending on the antenna configuration. Alternatively, the ISP3010 can operate as a standalone tag with a powerful onboard floating-point processor. It has digital interfaces allowing it to be integrated into larger, highly complex positioning solutions. The UWB communication is IEEE802.15.4-2011 compliant.

The device is built around the DecaWave DW1000 single chip UWB transceiver and nRF52832 Nordic Semiconductor 2.4 GHz wireless System on Chip. It includes a 32-bit ARM Cortex M4 CPU, 512 kB flash memory, 64 kB RAM as well as analog and digital peripherals. It is also equipped with decoupling capacitors, 38.4 MHz crystals for UWB, 32 MHz and 32.768 KHz crystals for BLE, DC-DC converters, RF matching circuits and two antennas in addition to the wireless Systems on Chip. Low power consumption and advanced power management enable battery lifetimes of up to several months on a coin cell battery. Module prototypes are available now with mass production due to start in Q1 2020.
