Introduction
The RFS (Radio Frequency and Sensor) daughter card is designed for the applications such as
wireless control, environment monitor, and IoT (Internet of Things). The daughter card can be
linked to the FPGA development kit via the 2x20 Pin GPIO connector.
The daughter card include Wi-Fi and Bluetooth wireless capabilities and includes a lot of sensors.
Sensors include ambient light sensor, temperature sensor, humidity sensor, accelerometer,
magnetometer, and gyroscope. An UART-to-USB interface also be provided to communication with
Host PC.

1.3 Assemble the RFS Daughter Card
The RFS daughter card can be connected to any FPGA development kit that is equipped with a
2x20 Pin GPIO connector. It can directly connect to the FPGA mainboard or indirectly connect to
the FPGA board via a 40-pin IDC Cable. The pictures below show how the RFS daughter card is
connected to various Terasic FPGA Boards:
