This relay control PCBA is mainly used for low-power load switching and automation control. It integrates relay circuits, power-input components, signal-control chips, and terminal-block interfaces, and switches lamps, fans, door locks, small motors, and other low-power loads via external control signals. Ningbo MingXi supplies it through our
This miniature wired PCBA control board serves as an auxiliary power-switching and signal-driving unit for integrating embedded equipment. Pre-soldered input and output wires simplify assembly inside finished devices, with no extra connector required. Built on an FR4 substrate, it features a robust MOSFET switching circuit and protection components for stable perf
Most mass-produced bouncing pet toys use generic, off-the-shelf circuit modules with fixed programming, limited movement patterns, and static lighting. This custom PCBA is designed and manufactured specifically for interactive bouncing pet toys, so pet toy brands can offer play that keeps cats and dogs engaged. Ningbo MingXi delivers it as a
This custom control cabinet manages multiple roller shutters from a single panel. We built it for a Saudi industrial customer's warehouse and commercial building, covering daily operation and fire safety. Unlike a single-door control box, one cabinet gives centralized control of multiple roller shutters. Ningbo MingXi builds the control boards, internal wiring, an
This 190 × 65 mm relay-based PCBA uses a mix of SMT and through-hole components. It is built for projects that need discrete on/off control of local loads rather than complex data processing. Multiple onboard relays connect to external wiring through plug-in terminal blocks and switch power to connected hardware when they receive trigger signals. Ningbo Ming
This industrial interface PCBA is a tailored circuit solution we build for mid-sized automation equipment developers. It's designed to solve signal-connection challenges inside CNC machines, servo systems, and automated testing jigs, not for basic power switching. It serves as a dedicated bridge between your core control unit, servo drive components, external sens
This egg cooker control PCBA is developed for small kitchen appliance manufacturers. It combines temperature control, timing settings, key input, and heating-element drive in a compact layout. It suits egg cookers, multi-function breakfast machines, and similar small heating appliances, where cooking time and temperature level directly affect the user experience.
This smart wall switch PCBA adds remote app control and scheduled timer control to a standard wall switch. It is designed around real installation conditions because, in most smart wall switch projects, the hardest adjustments come from physical fitting inside the wall box, not the wireless function alone. Ningbo MingXi builds it for switch brands with finished fr
This multi-channel digital setting PCBA replaced the main control board for an EU-based machinery integrator whose standalone processing machines could no longer receive original spare parts. The old hardware used physical dials for parameter setup, and dial wear caused setpoints to drift after six to twelve months of continuous shop-floor operation, leading to in
This control board came from a project for an overseas machinery partner that builds heavy-duty cutting equipment for metal processing workshops. Their old controller tripped often under high-load cutting, and signal interference from nearby motor drives caused random stops during continuous production. We reworked the whole PCBA layout to fit their existing machi
This BLDC motor controller is a drive control solution for brushless DC motors in smart fitness equipment. Unlike brushed motor control schemes, it uses a field-oriented control (FOC) algorithm for efficient, low-noise, stable motor drive. It eliminates carbon brush wear, a common failure point in brushed motors, reducing maintenance costs and extending treadmill
This PCBA is an IO power control board dedicated for CNC cutting machines
