www.smartradarsystem.com 2.2.3 Mini-USB Connector The connectivity is provided through the mini USB connector over the onboard FT2232H(FTDI). The FT2232H is a USB 2.0 High Speed to Dual UART IC. 2.3 Switches and LEDs 2.3.1 Sense-on-Power (SOP) Switch The IWR6843 device can be set to operate in three different modes based on the state of the SOP lines. These lines are sensed only during boot up of the IWR device. The state of the device is detailed by Table 3.

PCB Storage and Handling Recommendations The immersion silver finish of the PCB provides a better high-frequency performance, but is also prone to oxidation in open environments. This oxidation causes the surface around the antenna region to blacken.
