Carewell ECG-1112 Mainboard 112L-00254 With VGA Network USB Interface Power Management Module

• Product Description

This is a core control and power management mainboard designed specifically for the Carewell ECG-1112 series digital electrocardiograph, with part number 112L-00254. Visually, the circuit board features a compact layout on a green PCB substrate. It integrates several key interfaces, including a VGA port for external display, a USB port for data transmission, and an RJ45 network interface. Additionally, the board is equipped with prominent inductor coils and large-capacity electrolytic capacitors (e.g., 1000μF), indicating efficient power filtering and management capabilities to provide stable voltage support for high-precision ECG signal acquisition. It is a critical replacement part for repairing faults such as failure to power on, no display, or connectivity issues on the ECG-1112 device.

• The function of the product

This mainboard acts as the combined "brain" and "heart" of the ECG-1112 electrocardiograph. It is responsible not only for distributing and managing power—ensuring that weak ECG signals collected by the analog front end are not interfered with by power noise—but also for processing this data, converting it into visual waveforms displayed on the screen (via VGA/LVDS), and enabling data storage and transmission through USB and network interfaces.

Use tips

1. It is strictly forbidden to plug or unplug ribbon cables on the board while powered on to avoid burning out interface chips.
2. Do not touch the gold finger contacts on the board to prevent oxidation which causes poor contact.
3. If the device still fails to power on after replacement, please check if the front-end power board or battery pack is functioning correctly.
4. This product consists of electronic components; please store it in a dry, room-temperature environment.
