Download ESP01 Datashee ESP8266 Pinout of ESP-01 ESP-01 Power Supply The ESP-01 can not connected to a USB power source. The only possibility is to connect the ESP-01 with a 3,3 V power source via the VCC pin
The ESP01 is simply an ESP8266 module installed on a miniature development board (24.8 x 14.3mm). There are only 2 pins of the ESP8266EX module that are exposed on the GPIO GPIO0 and GPIO2 as well as the pins RX et TX for programming and debugging via the serial port Step 1: ESP8266-01 Pins The ESP8266-01 is the smallest ESP8266 module and only has 8 pins. Of these VCC, GND, RST (reset) and CH_PD (chip select) are not I/O pins but are needed the operation of the module. This leaves GPIO0, GPIO2, TX and RX available as possible I/O pins, but even these have pre-assigned functions Das ESP-01 Modul besitzt 8 Pins, die so angeordnet sind, dass man es nicht direkt in ein Breadboard stecken kann. Deswegen und weil man sich wegen der fehlenden Beschriftung auch leicht vertun kann, empfehle ich die Anschaffung eines kleinen Adapters (siehe Foto). Man bekommt das Modul mit Adapter z.B. bei Amazon für 5 - 10 Euro
The ESP8266-01 is the smallest ESP8266 module and only has 8 pins. Of these VCC, GND, RST (reset) and CH_PD (chip select) are not I/O pins but are needed the operation of the module. This leaves GPIO0, GPIO2, TX and RX available as possible I/O pins, but even these have pre-assigned functions GPIO15 ist hier nicht von Interesse, da das ESP8266-01-Modul keinen herausgeführten GPIO15-Pin hat. Die Pinbelegung des ESP8266 ESP-01 für den Flashvorgang sieht dann wie folgt aus: VCC kommt an 3,3V extra Versorgungsspannung RST (Reset) bleibt offen - vor dem Programmieren kurz auf GND legen CHPD/EN/CS Chip Select kommt fest mit einem 1 KOhm Widerstand auf die 3,3V Versorgungsspannung TX.

One commonly problem that every one faces with ESP-01 is the powering up problem. The module is a bit power hungry while programming and hence you can power it with a 3.3V pin on Arduino or just use a potential divider. So it is important to make a small voltage regulator for 3.31v that could supply a minimum of 500mA The ESP8266 ESP-01 module has 8 pins only of which 4 can be used as I/O (input/output) pins (GPIO0, GPIO2, RX and TX), this number of I/O pins is not enough to run a 16×2 LCD screen which requires at least 6 pins. The solution is to add an I/O expander such as PCF8574 chip (I2C I/O expander)
Input analog voltage of ESP-01 module ranges from 0 to 1V. Development board based around ESP-12E module have input analog voltage ranges from 0 to 3.3V. So we have to keep in mind while writing a sketch to use A0 pin. PWM Pins. The ESP8266 allows PWM in all input/output pin from GPIO0 to GPIO16. PWM signals have 10-bit resolutions. SPI Pin Did you buy this USB to ESP-01 Adapter Board and found out that it can't be used for flashing the ESP-01? You're not alone.
