- Technical Brief Technical Specs (subject to change) 1. Introduction Walabot is a programmable 3D sensor that looks into objects using radio frequency technology that breaks through known barriers, bringing highly sophisticated sensing capabilities to your fingertips. Walabot uses an antenna array to illuminate the area in front of it, and sense the returning signals. The signals are produced and recorded by VYYR2401 A3 System-on-Chip integrated circuit. The data is communicated to a host device using a USB interface, which is implemented using Cypress controller. The left picture shows the backside of the board, with the VYYR2401 chip, the USB controller and the micro-USB connectors. The right picture shows the antenna array. This side should be directed towards the objects you want to sense. Page 1 -- Technical Specs -- 2. Features Three-dimensional radio-frequency based sensor Uses an array of linearly polarized broadband antennas Frequency range: Developer o 3.3-10 GHz (US/FCC model) o 6.3-8 GHz (EU/CE model) Starter o 6.3-8 GHz Based on VYYR2401 A3 System-on-Chip for signal production and recording Cypress FX3 controller for USB communication and data pre-processing Walabot interface connectors: o Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. o Single supply voltage 4.5-5.5v input for non-USB power applications. 2.1 Feature summary of Starter, Creator and Developer models Capability Model Walabot Starter Walabot Creator Walabot Developer Physical Number of antennas 3 15 18 Board size 72 mm * 48 mm 72 mm * 140 mm 72 mm * 140 mm External powering option No Yes Yes Software API capabilities Basic API functions Yes Yes Yes 2D acquisition Yes Yes Yes 3D acquisition No Yes Yes Multiport recorder (raw data) No No Yes Software application capabilities Breathing detection Yes Yes Yes Object detection Yes Yes Yes Short range imaging No No Yes Page 2 -- Technical Specs --
