Frequently Asked Questions
Common Queries About Our Products & Services
Find clear answers regarding our authorized DWIN display stock, custom engineering processes, MOQ, prototyping timelines, and post-delivery support.
Yes. Neocent Electronics is officially authorised by Beijing DWIN Technology Co., Ltd. to sell, market, and support DWIN smart HMI displays in India. All displays purchased from us are 100% genuine with factory warranty and technical support directly from our Ahmedabad engineering facility.
DWIN smart displays contain their own dual-core T5L ASIC processor. The GUI interface, fonts, images, and touch logic run entirely on the display itself. Your host MCU simply communicates over a standard 4-pin UART serial port (TX, RX, VCC, GND) using simple byte packets, requiring zero display memory or rendering overhead on your MCU.
Yes. We offer end-to-end HMI screen engineering: from graphic icon layout and animated dashboard design in DGUS II to writing the communication firmware routines on your host microcontroller to control buttons, sliders, graphs, and indicators.
We believe in supporting innovation at every scale. For standard DWIN displays in stock, our MOQ is 1 unit so you can develop and validate prototypes without high initial costs. For custom turnkey electronic hardware, we support prototype runs through full-scale commercial manufacturing.
Yes. Our hardware team designs custom multi-layer PCBs using professional KiCad EDA. We handle component selection, power supply regulation, impedance-matched antenna routing, thermal management, DRC validation, and turnkey bill-of-materials (BOM) sourcing.
We architect connected IoT devices using Wi-Fi, BLE 5.0, 4G LTE-M, NB-IoT, and RS485 Modbus. We integrate hardware with AWS IoT Core, Azure IoT Hub, and private MQTT/HTTPS brokers with mTLS encryption and automated remote OTA firmware updates.
We provide comprehensive documentation, schematic files, firmware source code, and DWIN_SET project files. We stay with your product through bench validation, field pilot testing, assembly jig preparation, and subsequent firmware revisions.
We are located in Ahmedabad, Gujarat, India. Our laboratory is equipped with digital oscilloscopes, protocol analyzers, SMD rework stations, and test jigs for rapid benchmarking and prototype assembly.
