ESP8266-01 node
Soooo… Months ago I started working on ESP8266 based projects. One of them is a simple PCB with a connector for mains voltage in, 100mA fuse on to provide a bit of protection, switching power supply to convert the mains power into 5V DC, a LDO linear 3v3 regulator to bring the 5V down do a voltage the ESP8266 likes, two n-channel mosfet to drive the relay, relay terminals for connecting something, and then of course the ESP8266 itself.
The board isn’t made for something specific, so if I don’t need the relay, I just leave the components for that out, and use the 1×4 headers at the bottom of the PCB instead. And if I don’t need mains power, 5V can just be connected to the + and – terminals that normally are under the power supply.
Files for the board will be on Github soon(tm).

Hi would you able to send me the BOM for this board? I can work out the rest but i need the values for these C1-C7, Q1-Q2, Diode1
Q1 and Q2 are both a BSS138N.
C7 is a 1uF and C1-C6 are 10uF.
Diode1 is a 1N5824.
Thank you
Hi, what will be the resistor values…and what is U$4..
Sorry I’m totally out of the electronics field.. Im mech..
