This video is about Digikey tool, Scheme-it. It is easier than X-circuit. It can be used for drawing circuits for research papers such as IEEE. The main thing is, it is fully free. Tool link: https://www.digikey.com/schemeit

In this video, we will see how ESP-01 or ESP-12E can be programmed using NodeMCU. It is the easiest way to program esp modules.

In this video 48 pins QFN IC is soldered using a hot air gun and a fine tip soldering gun. IC used in this video is ESP-32. link for Milliscope: https://www.youtube.com/watch?v=LDwF3FOTAQI

In this Video, STM32F401RET6 (ARM Cortex-M) IC which is in QFP package is soldered on QFP adapter PCB. Also for testing this STM32 IC, it is programmed using STM32CubeMX IDE.
