SE100 Introduction

RadioLink M8N GPS SE100, benefits from 18 years of professional wireless experiences of RadioLink engineers, exceed the limitation of IC sensitivity index from circuit schematic design to PCB placement.
50 centimeters position accuracy. Positioning 20 satellites in 6 seconds at open ground. Industry-leading valley station-keeping ability.Radiolink M8N GPS SE100 Module High Positional Accuracy Works with GLONASS/BeiDou for APM Pixhawk Flight Controller DIY FPV Drone, Quad and More.

SE100 is suitable for all the open-source flight controller such as PIXHAWK, APM, NAZE32 and so on.

SE100 Configuration

GPS decoder chip: RadioLink M8N GPS SE100 use the best receiving chip of first GPS brand u-blox UBX-M8030(M8), 72-channel, MMIC BGA715L7 from Infineon, is much better than single GNSS 7N.

Built-in electronic compass QMC5883L (I2C port) with high precision, which is the same technology as Honeywell HMC5983

Humanized positioning green LED indicate. When SE100 is powered on, the indicators near the antenna are always on, when the satellite is found, the indicators near the antenna are always on, and the other indicators are blinking.
Definition of Connector
Connect to PIX: Red wire-VCC, White wire-TX, Orange wire-RX, Black wire-GND, Green wire-CLK, Yellow wire-SDA
GPS Mainboard: White wire-RX, Orange wire-TX, Red wire-VCC, Black wire-GND, Green wire-CLK, Yellow wire-SDA
Direction Indicate
Arrows shows the front, point to the same direction as the flight controller.
Keep the same direction with flight controller.
GPS connect to PIXHAWK
6pin for GPS connect port: Pay attention to the installation direction,
the GPS direction is consistent with the flight control direction.
4pin for I2C connect port: Take off the internal compass of APM. Otherwise,
there is no data even if the GPS compass is plugged in.
