HJ-P3029_LD-P400
Overview
The HJ-P3029_LD-P400 is a compact, low-power LoRa-based wireless transceiver module designed for the 410MHz to 460MHz frequency band. Based on the PAN3029 core, it provides robust long-range communication using ChirpIoT technology while maintaining a small footprint via its postal stamp hole surface-mount package. With a sleep current of only 1uA and a maximum transmit current of 91mA at 20dBm, it is optimized for battery-powered end-nodes.
Why Choose This Part
The module features exceptional sensitivity and anti-interference capabilities, making it reliable for deep-indoor and long-range outdoor links. Its extremely low power consumption in sleep mode (1uA) significantly extends the operational life of remote battery-operated devices. The small 11.6mm x 11.5mm form factor with a 1.27mm pitch allows for integration into space-constrained hardware designs.
Applications
Key Specifications
Getting Started
To begin development, interface the module with a microcontroller using the SPI bus and provide a stable 2V to 3.6V power source. Developers should integrate an external antenna tuned for the 410-460MHz range to the RF output pin. For software, utilize libraries compatible with the PAN3029 core or standard ChirpIoT protocols to configure frequency, bandwidth, and spreading factors.
