Ai-Thinker GP-01 BDS+GPS Development Board

Description

Ai-Thinker GP-01 BDS+GPS Development Board The Ai-Thinker GP-01 BDS+GPS Development Board is a compact, highly integrated SOC development board designed for satellite navigation applications. Equipped with a built-in ceramic antenna and a high-performance BDS/GNSS multi-mode satellite navigation receiver, it’s perfect for positioning and navigation projects. Powered by the AT6558R satellite positioning chip, this board integrates a radio frequency front end, digital baseband processor, 32-bit RISC CPU, power management, and active antenna detection and protection functions. Features Highly integrated SOC development board with a built-in ceramic antenna High-performance BDS/GNSS multi-mode satellite navigation receiver Powered by the AT6558R satellite positioning chip Supports BDS, GPS, and GLONASS for multi-system joint positioning NMEA protocol support for seamless integration Serial communication interface (UART) with a maximum rate of 256000bps Compact size: 23.4mm x 12.2mm x 24mm Wide operating temperature range: -40°C to 85°C Low power consumption with sleep and standby modes RoHS certified for environmental compliance Specifications Parameter Value Model GP-01-Kit Size 23.4 x 12.2 x 24 mm Operating Temperature -40°C to 85°C Storage Environment -40°C to 125°C, <90% RH Power Supply 5V (via Micro USB) UART Rate Up to 256000bps Certification RoHS Time to First Fix (TTFF) – Cold Start ≤32s Time to First Fix (TTFF) – Hot Start ≤1s Time to First Fix (TTFF) – Recapture ≤1s Sensitivity – Cold Start -148 dBm Sensitivity – Hot Start -156 dBm Sensitivity – Recapture -160 dBm Sensitivity – Tracking Mode -162 dBm Positioning Accuracy <2m (1σ) Timing Accuracy <30ns (1σ) Speed Measurement Accuracy <0.1m/s (1σ) Positioning Update Rate 1Hz (max. 5Hz) Power Consumption – BDS/GPS Dual-Mode 23 mA Power Consumption – Sleep Mode 20 μA Power Consumption – Standby Mode 8 μA Reset Voltage (aVDD_IO) 2.35V to 2.6V (Typical: 2.45V) Reset Time (Crystal Frequency 26 MHz) 160 ms TCXO Crystal Frequency 26 MHz TCXO Amplitude 0.5Vpp to 1.5Vpp Active Antenna Detection Current 2.5 mA Active Antenna Short Circuit Protection Current 45 mA to 60 mA (Typical: 50 mA) Antenna Detection Circuit Voltage Drop 0.3V (at 3.3V, 50 mA load) Working Current (BDS+GPS at 3.3V) 23 mA Battery Backup Current 8 μA Sleep Mode Current (ON_OFF = 0) 20 μA RTC Crystal Frequency 32.768 kHz RTC Crystal Equivalent Series Resistance ≤80 kΩ RTC Crystal Series Capacitance 8 pF Pin Definitions GND: Grounded VCC: 5V power supply RX1: General GPIO, default RXD of UART0 TX1: General GPIO, default TXD of UART0 GND: Grounded VCC: 5V power supply N/F: Shutdown control, internal pull-up PPS: Time pulse signal Micro USB: Power supply only Pin Definition Applications Satellite navigation and positioning systems GPS tracking devices Location-based services (LBS) IoT projects requiring precise location data Autonomous vehicles and drones Surveying and mapping applications Timing and synchronization systems DataSheet gp-01_kit_DataSheet
