so im totally new to making pcb, i have struggled the last few days trying to layout my circuit. one i couldnt find the proper esp8266 that i use.
im trying to make a board that i can just drop the esp into. drop an ads1115 into , and have terminal blocks connected to spots for ease of adding my external devices to the control board.
ie. 1-wire temp sensors, presssure transducers, channel relay's ....
i think i have it figured out. but how do ensure the size is correct for my specific esp, and how do i add art and discriptions of each hole being placed on the board.?
