RDR-3200 User Manual 1. Introduction RoyalTek RDR-3200 is the newest generation of RoyalTek GPS module integrated Dead Reckoning technology. The RDR-3200 includes dead reckoning sensors to track your vehicle's course when your GPS signal is blocked for example in urban areas or tunnels. If you lose GPS coverage in areas with tall buildings or tunnels, the RDR-3200 keeps on navigating. This document describes the recommended schematic and layout design of gyro and odometer circuit, and

RDR-3200 User Manual 4.2 Application Circuit Figure 1 illustrates the proposed schematic diagram of Gyro, odometer and RDR-3200. RDR-3200 supports the Gyro, Panasonic. Please care about the ground partition design among Gyro circuit, RDR-3200 and odometer input. It would be better to use 2 kinds of ground. The input of odometer is around 12V typically. It transfers the voltage level to accommodate the I/O voltage level of RDR-3200. The photo coupling transistors also isolate the noise
