ATGM336H GPS Module Beidou BDS Dual Mode Module Flight Control Satellite Positioning Navigator

Introduction:

The ATGM336H is a compact, low-power Global Navigation Satellite System (GNSS) module that provides positioning, navigation, and timing data. It is a popular, low-cost alternative to other modules like the NEO-6M for hobbyist projects with microcontrollers such as Arduino and Raspberry Pi

Applications:

• Arduino and Raspberry Pi projects: Used in DIY applications that require GPS tracking, such as wearable trackers, robotics, and small drones.
• Vehicle navigation: Provides positioning data for in-car systems.
• Handheld devices: Can be integrated into portable equipment that requires precise location information.
• Wearable technology: Its small size and low power consumption make it ideal for wearable trackers.

Specifications:
            

• Supported Systems: BDS, GPS, GLONASS, (multi‑GNSS) 
• Horizontal Accuracy: ~2.5 m (CEP, open sky) 
• Sensitivity: Cold‑start ~ −148 dBm; tracking ~ −162 to −163 dBm 
• Cold start TTFF : ≤ ~32 s 
• Hot or re‑acquire : ~1 s 
• Supply Voltage: ~3.3 V (some range 2.7‑3.6 V) 
• Current / Power Consumption: < ~25 mA @ 3.3 V during tracking/normal operation; lower in some standby or simpler variants. 
• Communication Interface: UART (default 9600 baud in many modules), some provide additional interfaces in chip form. 
• Operating Temperature: −40 to +85 °C
