ESP8266 wiring schemas
In this page I want to collect some examples (of increasing complexity) to connect the ESP8266 to Arduino boards. All the wiring schemes and examples are based on an Arduino One and an 8-pins ESP8266 module also know as ESP-01. Arduino pins 6 and 7 will be used as a second serial port using SoftwareSerial library as described here. Schema Power RX TX 1) Basic N N N 2) Powering with diodes Y N N 3) Powering with Zener diode Y N N 4) Powering with voltage regulator Y N N 5) RX level shifter…
