DSO138 2.4″ TFT Pocket-sized Digital Oscilloscope Kit DIY Spare Parts E-Learning Kit

DSO138 2.4″ TFT Pocket-sized Digital Oscilloscope Kit:

A digital storage oscilloscope (DSO), a device that digitally stores and analyzes signals, has become the predominant choice due to its advanced trigger, storage, display, and measurement capabilities. This comprehensive kit equips you with everything necessary to construct your own fully functional digital oscilloscope. Once operational, the oscilloscope boasts features such as up to 5M samples/second, 8-bit resolution, a maximum input voltage of up to 50Vpp, and more.

The kit includes a semi-populated PCB, featuring pre-soldered surface mount components, with the remaining through-hole components left for user soldering. While on the higher end of through-hole kit difficulty, this kit offers a rewarding build experience.

At Dhaka Robotics, DSO138 2.4″ TFT Pocket-sized Digital Oscilloscope Kit, functioning as a controller board with an integrated color LCD, incorporates all control elements, including slide switches, push-buttons, signal input sockets, and the power supply. Input coupling and amplitude adjustment are managed by mechanical slide switches on the left, while additional functions are selected using buttons on the right. The operation is intuitive, and DSO138 is partially open-sourced.

At its core, DSO138 2.4″ TFT Pocket-sized Digital Oscilloscope Kit on the Cortex-M3 ARM processor (STM32F103C8) from ST, complemented by a 2.4-inch TFT LCD (320 X 240 dot matrix, 262K colors) for displaying sharp and clear waveforms.
