Its also highly likely that this "MP4" player converts video files to a MJPEG-like format using a PC transcoder for playback on the device as there does not seem to be any DRAM in the system based on the teardown.
This brings back memories of the "Super Shuffle" iPod shuffle clones that emerged after the original was launched.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
