Description
A08B‑0082‑H021 is an internal printed circuit board used inside FANUC PANEL i display units that have embedded PC‑style functionality — specifically the 12.1‑inch LCD PANEL i models with PC/embedded system capabilities. It is one of the core PC system / main logic boards that serves as the processing heart of the PANEL i’s internal PC subsystem.
🧠 Function & Role
-
🧩 Internal PC System Board: Provides the core computing functionality in PANEL i display units that include an embedded operating environment (for example, for file management, program viewing/editing, or richer GUI features).
-
🛠️ Processor & Interface Logic: It typically hosts the CPU, memory interfaces, and chipset needed to run the PANEL i’s internal software, handle graphics, communication with the CNC controller, and manage I/O for the display subsystem.
-
📺 12.1″ LCD Compatibility: According to FANUC maintenance references, this board corresponds to the internal PC board for 12.1‑inch LCD PANEL i units with PC functions (a later revision compared to early H011 boards).
📋 Application Context
This board is inside the PANEL i assembly — it’s not an external operator control — and is used in display variants that function like embedded PCs (e.g., PANEL i screens that run embedded software, provide file handling, or have richer GUI features). It works together with components such as:
-
Internal storage modules (HDD units like A08B‑0082‑H100)
-
Memory modules (DRAM cards)
-
LCD driver / inverter boards
-
Interface connectors to the CNC controller
Together, they make the PANEL i unit both a display and a PC‑style interface for the CNC system.
