Step 1: Power Up Your Board with a Micro-USB Cable
Plug in one end of a Micro USB cable to the power connector of the LinkIt Smart 7688 and the other end of the
cable to a USB power source, such as your computer as shown in Figure 1, or a USB power adaptor. Make sure
you connect the cable to the Power (PWR) connector, not the USB host (HOST) connector near the MPU reset
button. The Power LED (Green) will light up solid first followed by the Wi-Fi LED (Orange) which will blink once.
Then, after about 4~5 seconds, the Wi-Fi LED will light on solid; this indicates that the boot loader has
initialized.
After boot loader initialization, the boot up process begins, which takes about 30 seconds. Next, the Wi-Fi LED
turns off; this means the system is ready to accept a Wi-Fi connection. Figure 2 shows how the Wi-Fi LED status
matches the system state.
