2.4.1 SmartSonic Connections to Run the Cliff and Floor Detect Demo Software
1. Connect one end of the 8POS FFC cable to the Sensor-0 connector and the other into the CH101 sensor module. Repeat this
for the Sensor-1 connector and the second CH101 sensor module. The blue LED next to each connector will light up if
connected correctly (see Figure 6). If an LED does not light up, check the cable connection and/or flip the cable orientation
and try again.
2. If not already done, for power selection, move the jumper to short the FTDI pins (as shown in picture).
3. Connect all (4) J3 jumpers (as shown in picture).
4. Toggle the switch from U15 to J6 to use Sensor-0, and NOT the on-board sensor.
5. Connect the micro-USB cable to the UART/USB micro-USB connector.
