NEO-7M GPS Module (GY-NEO7M V2) with EEPROM for MWC and APM2.5

The GY-NEO7M V2 is a compact GPS board built on the u-blox NEO-7M receiver, made for MultiWii (MWC) and APM 2.5 flight controllers on DIY multirotors and planes. It is GPS only, with no compass on board, so pair it with a separate magnetometer if your controller does not carry one.

Key features

• EEPROM stores configuration parameters through power-down, so settings survive between flights
• Ceramic active antenna on the board, with no external antenna needed
• Backup battery retains satellite data between power cycles for quicker fixes
• LED indicator shows GPS signal status
• Immersion-gold PCB measuring 23 × 30 mm

Specifications

• GPS receiver: u-blox NEO-7M
• Supply voltage: 3–5 V
• Default baud rate: 9600 bps
• Board size: 23 × 30 mm
• Compatibility: MultiWii (MWC), APM 2.5

Wire the module's TX and RX to your controller's GPS serial port, crossing TX to RX, and set the firmware's GPS baud rate to 9600 bps if it does not detect the receiver automatically.
