the device is .5 in square, with 5 pins esp8266 with antenna plug

hi, itˋs a bit tricky because this module has no gpio0 pin on the pin header. You have to search the gpio0 direct on the chip and connect it to ground while reset to bring it in flash mode. then you can flash it with the firmware flasher or Arduino ide or however you want

I guess I don't know enough about flashing the chip, and resetting. I found the gpio0 pin and grounded it. Ran the flash program and it wanted specific things that I don't know, like ip address and Mac address. Thanks for the advice. Troyboy
