DSO138 Digital Oscilloscope

Description

DSO138 Digital Oscilloscope is designed as a training oscilloscope. Simplicity in structure and ease of assembly/operation are the main objectives of the design. For these purposes, DSO138 is built with SMD parts, and the heart of DSO138 is a Cortex-M3-ARM processor (STM32F103C8) from ST. It uses a 2,4-inch TFT LCD screen (320 x 240 dot matrix, 262K colors) as the display element, which can display beautiful clear waveforms. Detailed assembly instruction and circuit diagram are provided.

The MCU is pre-programmed and no reprogramming required. With acrylic housing.
