RTL2832U + R860 SX1262 LoRa GPS / BDS / GNSS PCF85063A RTC TCXO Oscillator 5V Bias Tee 1.74GHz Max SDR Frequency 22dBm Max LoRa TX Power 3 Satellite Systems 4-in-1 Integrated Modules Core Modules Features in Detail 📡 Module 01 · RTL-SDR Software Defined Radio (RTL-SDR) Powered by the RTL2832U + R860 tuner combination, this module covers a wide frequency range from 100 KHz to 1.74 GHz. The onboard TCXO ensures temperature stability and near-zero frequency drift. The 5V Bias Tee can be enabled in software to power low-noise amplifiers (such as LNA4ALL, HABAMP, and RTL-SDR Blog ADS-B LNA) and active antennas directly through the coax cable. A side-mounted LED indicates the Bias Tee status at a glance. HF Direct Sampling mode enables reception from 100 KHz to 28.8 MHz.

An onboard TCXO oscillator ensures reliable, drift-free communication. Meshtastic is supported out of the box, enabling decentralized off-grid mesh networking over tens of kilometers without any base station infrastructure. LoRa ChipSemtech SX1262 Frequency Band860 – 960 MHz Max Output Power22 dBm OscillatorTCXO, near-zero drift Meshtastic SupportOut of the box Applications: Meshtastic off-grid communication, IoT remote sensing, wireless sensor networks, long-range data relay 🛰️ Module 03 · GPS Multi-Mode Satellite Positioning (GPS / BDS / GNSS) Compatible with GPS, BeiDou (BDS), and GNSS satellite navigation systems simultaneously. Multi-constellation positioning improves accuracy and reliability in challenging environments. Both active and passive GPS antennas are supported, making it adaptable to a wide range of installation scenarios — from drones and vehicles to outdoor tracking devices. Satellite SystemsGPS + BDS + GNSS Antenna SupportActive & Passive antennas Applications: Drone positioning, vehicle tracking, outdoor navigation, location data logging ⏰ Module 04 · RTC Real-Time Clock (RTC) Features the PCF85063A high-accuracy real-time clock chip, backed by a rechargeable 3V coin cell battery that keeps accurate time even when the board is powered off or rebooted. This directly addresses the lack of a hardware RTC in the Raspberry Pi, making it essential for any time-sensitive application that requires reliable timestamps across power cycles. RTC ChipPCF85063A Backup BatteryRechargeable 3V coin cellbattery Power-off TimekeepingContinuous, accurate timekeeping Applications: Data logging with timestamps, task scheduling, time-sensitive applications, event time-stamping Use Cases What can you do with it? 📡 Spectrum Analysis Use SDR++ or GQRX to scan the radio spectrum in real time and decode ADS-B, NOAA weather satellite signals, and more. 🌐 Meshtastic Off-Grid Mesh Build decentralized communication nodes that relay text and data over tens of kilometers — no cell towers required. 🚁 Drone & Vehicle Tracking Multi-constellation GPS delivers high-accuracy trajectory logging and real-time navigation for drones and vehicles. 🔌 IoT Sensor Node LoRa's long-range, low-power design paired with RTC precise timing makes it ideal for remote sensor data collection. 💾 Data Logging RTC ensures accurate timestamps across reboots, while GPS provides coordinates — perfect for scientific data collection. 📻 HF Signal Decoding Direct sampling mode covers shortwave and medium wave — receive weather balloon radiosondes, amateur radio, and more.
