My first PCB
Hello all
I got my first selfdraw PCB 2 days ago an i would like to share it with you
2 x MCP23017 portextender for up to 32 extra IOs.
Each channel can be setted by jumper as Input or output.
as input there is also a jumper to set a 10k pulldown resistor.
as output there is ULN2803 transistor arrays wich can be used by internal 5V supply or external 3-30V by jumperselection.
All other ports of the ESP are also available.
by jumper you can use a 4,7k pullup resistor for each IO.
plus there is a grid for own applications including GND, 3.3V and 5V connector nearby.
Basicly i did try to make a "one fits all" PCB
So what do you think ? (well, it is my very first PCB )
Have a great day
Sascha

Re: My first PCB
That's pretty cool! Will you be making it available for sale?

Re: My first PCB
Which program did you use to make the PCB? Would like to try and make a ESP8266 "motherboard" myself
