Price range: $ 16.00 through $ 18.00
Huidu R505 and R507 receiving cards for compatible A60X, A30/A30+, C30 and C10 sending systems. Compare the model-specific connectors and recommended 256 × 192-pixel loading. Review the document discrepancies before selecting a replacement.
Huidu R505 and R507 LED receiving cards
The Huidu R505 and R507 are receiving cards for compatible asynchronous LED control systems. They work downstream of a sending card and connect to the LED cabinet through the appropriate adapter interface. Their connectors differ, so select the exact model to match the existing cabinet hardware.

Check the board revision before replacement
The PDFs describe HDPlayer smart settings, configurable receiving-card order and onboard test patterns. They list support for conventional and specified PWM driver ICs, including MBI5041/5042, MBI5050, MY9221 and MY9268. Match the module driver, scan mode and adapter wiring before applying settings.
Source discrepancies: Both PDFs list maximum loading as “190,000 points, 1024 × 192”; these figures differ mathematically. Both give 4–6 V in one section and 4.2–5.5 V in the technical table, and temperature upper limits of 85°C and 80°C in different sections. The R507 port table lists eight HUB75E ports, while its appearance section describes four 26-pin outputs. Confirm these details against the supplied hardware rather than treating the conflicting entries as interchangeable specifications.

Frequently asked questions
What is the difference between the R505 and R507 connectors?
The R505 document describes two 60-pin outputs. The R507 appearance section describes four 26-pin outputs, but its port table says eight HUB75E ports. Check the actual R507 board and adapter pinout before purchase; do not treat the two models as plug-in equivalents.
What loading range should I use?
Both linked PDFs recommend 256 × 192 pixels. They also list “190,000 points” and “1024 × 192” together as maximum figures, which are not numerically identical. Confirm the intended module and scan configuration instead of relying on an assumed maximum.
Which sending cards are listed as compatible?
Both documents name Huidu A60X, A30, A30+, C30 and C10 asynchronous sending cards. Confirm hardware and firmware compatibility for the complete system before replacing a receiving card.
What voltage do these receiving cards require?
Both documents recommend a standard 5 V supply. Their technical tables list 4.2–5.5 V, while an earlier parameter section gives 4–6 V. Use the marked rating for the supplied board and confirm the power connection through the terminal or adapter board.
