Top-cofrLD DIY DSO138 oscilloscope production suite, e-learning training kits contest, open source STM32 oscilloscope DIY kits

Features
DSO138 was designed as a training oscilloscope kit. It contains only the basical oscilloscope functions with no fancy features. Simplicity in structure and easiness in assembly/operation are among the main targets of the design. For these purpose DSO138 uses mostly through-hole parts. The heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematc. Source codes are also available to allow user to add their own features.

DSO138 kits are solded in two configurations. One is with all SMD parts pre-soldered (PN: 13804K). . The latter serves also as a SMD soldering training kit. For both configurations the MCU has been pre-programmed and no re-programming required.

DSO138 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware.

Kindly Note:This is a kit you need to solder it by yourself (It is very easy and funny,you will enjoy the DIY) Note 1: A 9V DC power supply is required to run DSO138. Power supply is not included in the kit. It is recommended to use the 5V-to-9V Step-up Converter JYE140 to power DSO138 by battery or USB. [see Photo: DSO138 working with JYE140]
