The dAISy-Mini has two serial ports, TX1/RX1 & TX2/RX2. These ports are configured for 38,400 bps. The Neo-M8N is also configured for 38,400 bps. The output of the Neo-M8N is connected to TX2/RX2, with the Neo-M8N RX connecting to TX2, and the Neo-M8N TX connecting to RX2. The power pins on the Neo-M8N connect to VCC and GND as labled.
In Mainland China, excuse me, the People's Republic of China, Beidou and Glonass would be better choices for you. I'm not yet an expert on the M8N, but you might also be able to add the Galileo or GPS Constellations. You might also investigate the QZSS Constellation.
