ESP8266-12e Base Card

This is the first "Beta" version of the Base board for the ESP8266-12e Card project. At the moment, the card only contains i2c interfaces to all of the expansion slots, as well as status lines ( to be used for card detection and interrupt ) to each expansion slot. There is also a 3v SMPS in the form of an MP1584 module onboard. Future expansion should allow it to be used with ESP32 processors as well, and more GPIO will be broken out directly to the expansion slots. I have unfortunately made a stupid error on this board, in the form of mirroring the processor connector pins for the UART and I2C. It is still useable, but requires a lot of green wiring ( black in this case, to make it completely functional -- Things happen though, and nobody is immune to mistakes :( we are only human anyway... ) all that aside, PCBWay did their usual excellent work manufacturing this board. Thank you very much... No fault on your side at all :)

    First time for me. Excellent result soldered with electronic hot plate and hot air gun.
    perfect

    The Walkeremoteboard working good
    Basic prototyping parts but really straightforward ordering process, I very happy with the price, tolerances and surface finish. Delivery was tracked and on time, no hassle at all. Great Service!
    Perfect for my purpose.
    I am very satisfied with quality, haven't expected it to be this good. All of the critical dimensions are held to tolerance, surface finish and anodized finish is perfect, can't spot any problems with...
    Once again, PCBWay knocks it out of the park! Not a whole lot to say except that my board soldered up wonderfully, and looks great in the classic green color! Definitely going to be ordering more boar...
