Shell oscilloscope suite DSO138 upgraded version of electronic teaching practice DIY STM32 Suite
The "Shell" oscilloscope production kit is based on the popular DSO138 oscilloscope kit, which has been improved by improving the performance of the circuit, circuit board, mechanical structure and mode of operation (mainly higher sensitivity and range Wider), it is the perfect replacement for the DSO138 oscilloscope kit.
In the circuit structure, the digital part (mainly MCU and LCD) and analog part is divided into two circuit boards, to avoid the use of pin connection, and row pin welding problem is caused by DSO138 package production failure of the main reasons. The analog board contains the components that most users install and solder, and the independent analog board can be better isolated from the digital part. As the motherboard does not contain analog parts, so the motherboard can also be used as a common control board, with a wide range of applications. Motherboard in addition to a small part of the direct part of the chip components are mostly pre-assembled and tested at the factory, and pre-written procedures into the microcontroller.
