Import Ds211 Mini Portable Lcd Digital Oscilloscope — Buy in wholesale FOB from Supplier in China

The DS211 is a compact digital storage oscilloscope based on the STM32F103VC microcontroller, featuring a 320x240 color LCD screen and a single analog input channel with 200kHz bandwidth. It samples at up to 1MSa/s with 8K memory depth and supports vertical sensitivity from 20mV/div to 10V/div in 1-2-5 steps. The device includes an internal channel for signal generation and operates on a 550mAh rechargeable lithium battery, weighing only 65g with the battery installed. Its physical dimensions are 106.5mm x 55.7mm x 11.5mm, making it suitable for field use or integration into embedded projects.

The oscilloscope uses the MCU's internal ADC and supports DC/AC coupling with rising or falling edge triggering. It offers auto-fit waveform adjustment and manual sweep speeds from 1us/div to 2s/div. Signal outputs include square, sine, triangle, and sawtooth waves, with measurement functions for frequency, period, duty cycle, peak-to-peak voltage, RMS, average, and min/max values. The 8MB built-in USB flash storage allows waveform capture and transfer via Micro USB, and the application layer is open source, enabling custom firmware development for STM32-based projects.

This device is commonly used by electronics hobbyists, students, and field technicians for basic circuit debugging and STM32 microcontroller development. Buyers often integrate it into portable diagnostic kits or use it alongside multimeters for low-frequency signal analysis. It is supplied with a dedicated MCX probe, micro USB cable, protective bag, and manual. Packaging is standard for bulk orders, and lead time is typically 5 - 10 business days after payment confirmation. Buyers should verify firmware version and probe compatibility before large-scale deployment.

Shenzhen Weikexiu Technology Co., Ltd. is a hardware development company based in Longgang District, Shenzhen, specializing in open-source electronic test instruments and STM32-based educational kits. The company's address is registered in the Juguang E-Commerce Industrial Park, indicating a focus on manufacturing and distribution rather than large-scale OEM production. Their listing shows no verified certifications beyond CE and FCC, and no public information exists regarding company size, revenue, or export history.

The supplier has a harbor trust tier and no recorded response rate or average response time, suggesting limited buyer engagement or automated listing management. They do not claim ISO certification, quality management systems, or third-party audit status. Their product portfolio appears limited to a few open-source oscilloscope and signal generator models, with the DS211 being their most documented item. Buyers should treat this as a niche supplier with technical product knowledge but minimal operational transparency.
