HamGeek RTL-SDR/LoRa/GPS/RTC/USB Hub Multifunctional Expansion Board with Antenna Mount Module for uConsole

Description:
- The uConsole Multifunctional Expansion Board is a powerful multifunctional expansion board designed to enhance the functionality of your uConsole device. This expansion board integrates multiple functions, including RTL-SDR, LoRa, GPS, RTC, and USB Hub, making it an essential tool for developers, hobbyists, and professionals.

RTL-SDR:
- Tuner: utilize RTL2832U and R860 tuner.
- Frequency range: supports a wide frequency range of 100KHz to 1.74GHz.
- Temperature compensated oscillator (TCXO): precisely tuned with almost zero temperature drift.
- 5V Bias: this allows RTL-SDR to power low-noise amplifiers (such as LNA4ALL, HABAMP, RTL-SDR BIog ADS-BLNA) and active antennas through coaxial cables. This feature can be enabled through software. The status of the bias power supply can be indicated by the LED indicator light on the side.
- HF direct sampling mode: Listen to 100kHz to 28.8MHz through direct sampling.
- Application: very suitable for software defined radio (SDR) applications, including radio scanning, spectrum analysis, and signal decoding.

For LoRa/Meshtastic:
- Chip: equipped with SX1262 chip
- Frequency band: operates in the 860-960MHz frequency range
- Output power: maximum output power of 22dBm
- TCXO: precisely tuned with almost zero temperature drift
- Application: ready to use, supports for Meshtastic. Very suitable for long-distance low-power communication projects such as IoT devices, remote sensors, and wireless networks.

GPS:
- Multi mode support: compatible with GPS, BDS, and GNSS satellite navigation systems.
- Antenna options: supports active and passive GPS antennas.
- Application: Enhance location tracking and navigation capabilities for various applications, including drones, vehicles, and outdoor activities.

RTC (Real Time Clock):
- Chip: adopting PCF85063A chip.
- Battery: use CR1220 battery (not included) to ensure continuous timing.
- Function: provide accurate real-time clock function to solve the problem of missing RTC in uConsole.
- Applications: it is crucial for time sensitive applications such as data recording, scheduling, and timestamps.

USB Hub:
- Ports: including Type-A and Type-C ports on the side.
- Internal connection: equipped with internal Type-C ports and 2.0mm spaced needles.
- Application: extended connection options that allow multiple USB devices and peripherals to be connected.

Package Included:
- 1 x Expansion Board
- 1 x Antenna Mount Module

Note:
- The uConsole is not included.
