DBstar HRV13S LED Display Receiving Card Description

The DBstar HRV13 Receiver Card is an upgraded, high-reliability receiver card designed for LED display systems, offering a wide-range DC power input, rapid correction loading at boot, robust firmware management, and enhanced EMC performance. It supports both chroma-correction and brightness-correction modes at high resolutions with 16-bit depth, and includes hardware features for online firmware updates, hot-swapping backup, board-level voltage and temperature monitoring, and multiple contact-pin options for flexible installation. The HRV13 is compatible with HRV11S and HRV12STM, making it an easy upgrade path for existing systems that need faster boot, improved EMI behavior, and more reliable firmware control.

Product Features:
• Wide-range DC power input: DC 3.6 V to 12 V for flexible system deployment
• High correction capacity: supports up to 256×256 pixels chroma-correction or 512×256 pixels brightness-correction at 16-bit depth
• Fast correction-coefficient loading on power-up to reduce display boot time
• Firmware management: firmware copying among same-type cards, read-back of firmware information, and parameter files
• Dual-backup design for hot-swapping and reliable online firmware updating
• Three contact-pin options (3-pin, 5-pin, 6-pin) for versatile key/indicator connections
• Board-level voltage and temperature monitoring for system health visibility
• Spread-spectrum design to reduce EMI and improve EMC for stable operation
• Backwards compatible with HRV11S and HRV12STM for straightforward upgrades
