SOLUTION: I took some long lead female headers and bent them with a little S-curve so that they will fit in a breadboard. PROBLEM: The ESP-01 module has 2x4 header that is not compatible with breadboards.(see first picture) So a separate 3.3Vdc power source is needed. (see picture) This is also true of the PL2303 serial converters that I use a lot of. The problem is that most of the power supplies are in the FT232 IC and are only capable of supplying about 50mA of current. SOLUTION2: So many FTDI converters have the option of converting logic to 3.3Vdc. SOLUTION1: So some ESP8266 modules have built in 3.3Vdc regulators and are compatible with 5Vdc USB to serial devices.Īdafruit HUZZAH ESP8266 Breakout( )(see picture) Also, it may need up to 250mA of current. PROBLEM: The ESP8266 IC requires 3.3Vdc instead of the more common 5Vdc. Most computers use USB to serial converters, like FTDI chips. Most communications with the ESP8266 is serial. Some of the cheaper ones are ESP-01, ESP-03. As usual she provides thorough, useful information.Īlso, much of my information comes from this website: Special thanks to Lady Ada, Adafruit and the Adafruit HUZZAH ESP8266 breakout module. Now there is already a lot of information on doing this but I found it confusing, hard to figure out, sometimes misleading so I hope to simplify and clarify the process. The ESP8266 is a microcontroller similar to the AtMega328 used in the standard Arduino, e.g., Arduino UNO. Well, what I wanted to do was use the ESP8266 as an Arduino without having to use a standard Arduino. But most of these are using the ESP8266 as a sensor/WiFi connected to a standard Arduino. There are many Instructables with this chip and many with an Arduino.
Basically, it’s a microcontroller that does WiFi. So this Lazy Old Geek (L.O.G.) heard about this ESP8266 IC.
