[Disassembly] Monument This is a low-power Bluetooth device, and this tiny circuit board integrates six types of sensors. Let’s see what it can transmit. ▽ It is called “Monument” because it looks like a stone tablet. ▽ Stripped of its fancy attire, revealing the transparent “xq underwear”. ▽ Shyly turning away. ▽ Screwless design for … Read more
Part One: Design Guidelines for Mixed-Signal Circuit Boards The operation of analog circuits relies on continuously varying currents and voltages. Digital circuits operate by detecting high or low levels at the receiving end based on predefined voltage levels or thresholds, which corresponds to determining the logical states of “true” or “false”. Between the high and … Read more
