Description:
NEO-6M is a compact, high-performance GNSS receiver built around the proven u-blox 6 engine. Designed for makers, robotics and embedded projects, this module includes an integrated 25×25 mm active/ceramic antenna and a backup RTC battery so the module retains satellite almanac/ephemeris for faster hot/warm starts.
The module communicates over UART (TX/RX) using standard NMEA or UBX messages and is compatible with Arduino, ESP boards, STM32 and Raspberry Pi. Plug into 3.3–5V systems (level-tolerant modules available) and begin receiving position (latitude, longitude), UTC time, speed and satellite data instantly.
Why Choose This Module:
- Proven u-blox NEO-6 engine for stable satellite tracking and industry-standard protocols.
- Integrated 25×25 mm antenna for compact, strong reception in hobby/field use.
- Backup RTC battery maintains TIME/ALMANAC for faster warm/hot start.
- Easy UART hookup and 3–5V power compatibility — ideal for Arduino & Raspberry Pi.
Specifications:
- Chipset: u-blox NEO-6 series.
