Description
[Discontinued] DSO203 4-Ch Handheld Mini Digital Oscilloscope
DESCRIPTION
DSO203 is based on ARM cortex M3 (STM32F103VCT6) 32 bits platform, providing 72MS/s sampling rate with integrated FPGA and high-speed ADC. Internal 8MB USB disk could be used to store waveform, user application and upgrade firmware.
Note: Due to the metal conductive shell of DSO 203, its operating voltage should be controlled under 40V during working in case of any damage to the Quad itself or human
