<p>I've been playing with a few nodemcu boards and came across an
issue didn't expect... <br>
</p>
<p>I got a 'standard' nodemcu esp8266 boards some time ago with
CP2102 usb to serial converter. <br>

</p>
<p>I then decided to get a break out board for them to make
experimenting easier. I found a board called "New Expansion Board
V3 Lua Breakout Development Boards for ESP8266 CH340G NodeMcu"</p>

<p>Its a typical advert from china, all sort of buzz words to try
and make you buy their stuff.</p>
<p>But in this case there is one very important keyword CH340G. It
turns out the nodemcu boards that have a CH340G usb/serial
converter are 2*2.54 mm wider than the same board with a CP2102
usb/serial converter!</p>
<p>So my breakout board socket is to wide for the narrow nodemcu
board...</p>
<p>easyeda and jlpcb to the rescue, I quickly made a physical
converter pcb. No worries. <br>

<p>Now I noticed the board I made was really quite small and I had
been wanting to try out the pcb paneling option for a while since
it doesn't cost any more as long as you stay under 100x100mm
total.... I now have 60 converter pcb's, when of course I only
needed 2-3!</p>
<p>So if anyone has the need for a pcb to converter from 22.86mm
wide 15 *2.54mm pins long to 27.94mm wide, let me know! Free to a
good home, but donations would be appreciated. <br>
</p>

</p>
<p>I do wonder if a pcb trading site is needed, as I suspect i'm not
the first or the last to end up with extra pcb's that could be
re-homed. <br>
