Roborock S7 Pro Ultra Mainboard TOPAZ-S MAIN B2.0 Control Board
- Replacement mainboard for Roborock S7 Pro Ultra, model TOPAZ-S MAIN B2.0. PCB control board designed for internal electronic repair, system control, sensor communication, and stable device operation.
The Roborock S7 Pro Ultra mainboard TOPAZ-S MAIN B2.0 is an internal electronic control board designed as a replacement part for the Roborock S7 Pro Ultra robot vacuum. As the central PCB of the device, it manages communication between key components and supports the core operating functions required for proper system performance. This mainboard is built for model-specific compatibility with the Roborock S7 Pro Ultra and carries the board designation TOPAZ-S MAIN B2.0. It integrates multiple electronic circuits, chipsets, connectors, and control points used to link internal modules such as sensors, drive systems, power management elements, and other onboard assemblies.
The board layout includes dedicated connector ports for ribbon cables and component interfaces used inside the robot. In operation, the mainboard acts as the primary control unit, processing signals and coordinating the response of the vacuum’s internal systems. It supports data exchange between electronic modules and helps maintain synchronized performance across cleaning, navigation, charging, and hardware monitoring functions, depending on the connected components and repair context.
As a replacement spare part, this PCB is intended for technical servicing, maintenance, or repair of a compatible Roborock S7 Pro Ultra unit. It can be used when restoring the device after electronic failure or when replacing a damaged original board with the same board version. Matching the correct board model helps ensure proper fit, connector alignment, and integration with the existing hardware architecture of the vacuum cleaner.
