MEB-1000 User Manual 1.8 Application Circuit Figure 4 Application Circuit Note: (1) Serial Interface: (Ⅰ)The TXA & RXA pin is recommended to connect to serial resistance(220 Ω) and pull up (10KΩ). It can increase the stability of serial data. (Ⅱ)The TXB & RXB pin is recommended to connect to serial resistance(220 Ω) and pull up (10KΩ), if use the DGPS output. If no use DGPS output, it don’t connect anything. (2) Backup Battery: It’s recommended to connect a backup battery to V_RTC_3V3.

MEB-1000 User Manual capacitor(10uF and 1uF).It can reduce the Noise from power supply and increase power stability. (5) Active antenna bias voltage: The Vcc_RF_OUT pin(pin 20) is provide voltage 2.85V. If you use active antenna, you can connect this pin to V_ANT_IN pin (pin 19) to provide bias voltage of active antenna. The bias voltage will be through GPS_RF_IN pin to provide active antenna bias voltage from Vcc_RF_OUT pin. If your bias voltage of active antenna isn’t 2.
