Choose the L7 receiving card for the cabinet wiring
Mooncell L708, L712 and L716 are FPGA receiving cards with HUB75E output connectors. They support point-by-point correction, AutoLED configuration, custom cabinet layouts and network-cable diagnostics, while their connector counts and RGB data groups differ.
The original shared description’s twelve-interface count applies to L712. L708 has eight and L716 has sixteen according to their separate specifications. Use the appropriate correction-load row as well as the maximum-load row when checking a cabinet, and confirm customized monitoring features on the supplied hardware.
Technical specifications
| Parameter | Specification |

| Scan support | 1–64 scan, listed for all three models |
| Cascade quantity | Up to 1000 cards, as listed in each PDF; system bandwidth and screen configuration still need to be matched. |
| Correction | Point-by-point brightness and chroma correction with correction software |
| AutoLED display functions | Refresh-priority or grayscale-priority settings, rotation in multiples of 90°, and image scaling |
| Configuration | Custom output-data interfaces, complex cabinet/module layouts, receiving-card number detection and configuration readback through AutoLED |
| Diagnostics / backup | Network error-rate monitoring, receiving-card communication monitoring and network-cable loop backup |
| Customized monitoring | Voltage, temperature and power-supply-status detection are identified as customized functions. |
| Input / rated current / rated power | All three PDFs: DC 3.5–5.5 V; 0.6 A; 3 W |
| Operating environment | −20 to 70°C; 10–90% RH |
| Storage temperature | −25 to 125°C, as listed in the PDFs |
| Board dimensions | 144.02 × 91.19 mm for all three documented models |
| Net weight | L708: 82.1 g; L712: 100.8 g; L716: 106.7 g |
| Document versions | L708: update history through V3.2; L712: V3.5 / hardware V2.0; L716: V3.3. Match the actual board revision when replacing a card. |

Frequently asked questions
How do L708, L712 and L716 differ?
Their HUB75E connector and RGB-group counts differ: L708 has 8 connectors and 16 groups, L712 has 12 and 24, and L716 has 16 and 32. The L716 document also lists a larger maximum and brightness-corrected load.
Does chroma correction reduce the documented load?
The parameter tables list 512 × 160 pixels for chroma-corrected loading on all three models. Brightness-corrected loading is 512 × 256 for L708/L712 and 768 × 256 for L716.
Can the display be rotated or arranged as complex cabinets?
The documents describe rotation in 90° increments, scaling, custom output data and complex module/cabinet arrangements using AutoLED. The configuration must match the actual modules and wiring.
Are voltage and temperature monitoring standard?
Those monitoring functions, along with power-supply-status detection, are marked as customized in the specifications. Confirm the required hardware configuration before relying on them.
Can I replace one L7-series card with another without changing settings?
Do not assume an unchanged setup. Check the exact model, hardware revision, HUB75E pinout, RGB-group count, scan mode, correction load and cabinet wiring. Retain the existing configuration and use the model-specific PDF during replacement.
