Beware of counterfeit modules

If your board just continuously flashes its led when powered on and no esp-01 is entered, the onboard STC15F104W needs to be programmed! For more details see https://www.esp8266.com/viewtopic.php?f=160&t=13164&start=68#p74262

Additionally once programmed, you may also have to remove r4, some issues exist where r3 and r4 are swapped, but just removing r4 works.
