4 Pack GY-NEO6MV2 NEO-6M GPS Module (3V-5V) with Ceramic Antenna
Quick take
This 4-pack GY-NEO6MV2 GPS module set targets DIY and avionics-adjacent projects that need a compact UART TTL GNSS receiver. It supports GPS and GLONASS, stores configuration in EEPROM, and uses a built-in ceramic antenna for installation convenience. The tradeoff is mixed buyer experience across units, including reports of long first locks and, in some cases, modules that fail.
Pros and cons
Pros
- GNSS support for GPS and GLONASS, up to 22 satellites tracking (per module design).
- UART-TTL interface with adjustable baud rates (4800 to 115200 bps) for common microcontroller setups.
- EEPROM-backed configuration so parameters can persist across power cycles.
- Compact, mountable footprint (25 mm x 35 mm) with a small 3 mm mounting hole.
Cons
- Buyer review evidence is mixed on reliability, with some reports of total failures on one or more units.
- First GPS lock timing appears inconsistent, with some users reporting hours in the same conditions.
- It is a module-level GPS receiver, so it is not a drop-in navigation device for consumer use without integration work.
What buyers think
Buyer-review evidence for this 4-pack is limited but includes a clear split between “works well” experiences and problematic unit failures. Several buyers report that GPS lock can take time after power-up, followed by stable operation once a fix is achieved (including for telemetry uses where tens of meters accuracy can be sufficient). At least one review theme also points to inconsistent time-to-first-fix between units, even when conditions and location are the same. However, there are also multiple reviews indicating that some or all modules stopped working, including cases described as immediate failure and cases where a unit worked briefly and then died. Because of that mixed signal, reliability feels like the main buying caveat for this specific bundle.
What you get (and what it’s for)
The GY-NEO6MV2 is a GNSS module intended for projects that need latitude/longitude data from GPS, with GLONASS support included. This bundle is sold as four modules plus the associated ceramic antenna hardware described as part of the package. The module is designed to run from a 3V to 5V supply and communicate using a UART-TTL interface, which is a common match for microcontrollers and flight controller telemetry inputs.
Key specs that matter for integration
Power and serial interface
- Power: 3V-5V operation.
- Interface: UART-TTL.
- Baud rates: adjustable from 4800 bps to 115200 bps, with a default baud rate of 9600 bps.
GNSS performance features
- Satellite support: GPS and GLONASS.
- Tracking capacity: up to 22 satellites simultaneously.
- Sensitivity claim: -161 dBm tracking sensitivity (useful in the sense that it is designed for weak-signal conditions, though real-world lock time can still vary).
Antenna, size, and mounting
- Ceramic antenna: integrated, described as 25 x 25 mm.
- Module size: 25 mm x 35 mm.
- Mounting: a 3 mm mounting hole, intended to make installation into enclosures and platforms easier.
EEPROM configuration storage
The module includes EEPROM storage so configuration parameters can persist during power outages. That is helpful when you are repeatedly deploying prototypes or when your system restarts in the field, because you can avoid re-tuning settings every time.
Pros and cons, translated to real buying decisions
When this GPS module bundle makes sense
- You are building a DIY drone, vehicle tracker, or telemetry system where a UART GNSS receiver is the right component type.
- You want GPS plus GLONASS for potentially improved satellite availability, especially if your project area has limited sky visibility.
- You are comfortable with basic electronics integration (wiring TX/RX, matching baud rate, and handling first-fix behavior).
- You like the 4-pack format for experimentation, redundancy in prototyping, or keeping spares.
When you should be cautious or look elsewhere
- If you need mission-critical reliability, review evidence includes reports of modules failing, so this is better treated as a prototyping-oriented choice.
- If your project cannot tolerate long first locks, be aware that buyer experiences suggest lock timing can be inconsistent across units.
- If you want an all-in-one navigation solution, you likely need a different product category than a bare GPS module that requires integration.
How to get better results after install
Even though this is a plug-in module style approach, time-to-first-fix can vary. A few practical steps usually help with first lock reliability and consistency: place the antenna where it has a clear view of the sky, keep it away from dense RF interference from power electronics, and confirm your UART settings (default 9600 bps versus your device’s baud rate). If you are using a flight controller or microcontroller, double-check voltage compatibility and serial wiring polarity before assuming there is a GPS fault.
Price and availability
This bundle is listed as in stock at the time of this review, and it is positioned as a low-cost multipack option compared to buying a single higher-integration GNSS unit. If your budget allows, consider whether redundancy is enough for your use case, since the most important risk sign in buyer feedback is unit-level reliability variation.
Bottom line verdict
The 4 Pack GY-NEO6MV2 NEO-6M GPS modules are a solid fit for makers who want GPS plus GLONASS with UART TTL integration and EEPROM-backed configuration storage. However, mixed buyer evidence raises a legitimate concern about unit-to-unit reliability and inconsistent first-fix timing. If this is for prototyping, telemetry experiments, or hobby projects where you can test and swap units, it is a reasonable option. If you need consistent uptime across every installed unit, you should compare alternatives or plan for spare modules.
FAQ
How long does the first GPS lock take?
Buyer experiences vary. Some setups report a first lock after a short wait, while other experiences describe significantly longer time-to-first-fix. Plan for the possibility of extended waiting after initial power-up, especially if conditions are not ideal.
Does this GPS module support both GPS and GLONASS?
Yes. The module is designed to support GPS and GLONASS positioning.
What interface does the GY-NEO6MV2 use to connect to a microcontroller?
It uses a UART-TTL interface with adjustable baud rates. The default baud rate is listed as 9600 bps, and supported baud rates range from 4800 bps to 115200 bps.
Will the GPS module remember configuration settings after power loss?
Yes. It includes EEPROM for storing configuration parameters so settings can persist across power cycles.
Is a ceramic antenna included, or do I need to add one?
The module includes a ceramic antenna as part of the design, described as 25 x 25 mm.
Is this suitable for drones or flight controller use?
It is commonly used in drone and flight controller style projects because it is a compact GNSS receiver with UART TTL output. That said, review evidence is mixed on unit reliability, so testing and having spares can matter if your application is sensitive to failure.
