Abstract: ZigBee is an emerging short-distance, low-rate wireless network technology. This paper analyzes ZigBee technology, IEEE802.15.4 standard and related applications in detail, discusses their r
IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (ins
The pins of the cpld that connect +3.3V and ground start to smoke when powered on or when downloading a program, but there seems to be no short circuit on the board. Has anyone encountered a similar s
I would like to ask what does Ground plane removed under Vin- mean in this picture? Does it mean that V- should be separated when laying ground in PCB design? Why should it be separated?
