The FTDI connector can be found on just about any ESP8266 design. If you are building a gadget to be deployed somewhere and not a full blown development board, the FTDI connector is somewhat overkill. And itĀ is quite large. A few pins could be shaved off but we still have a through hole connector invading […]

Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush currents relative to their steady state currents that may be several times their normal full-load current when first energized. The inrush current of a power converter
