ESP8266 Shield for Arduino - ESP-12E

από OEM
Το ESP8266 ESP-12E UART Wireless WIFI Shield TTL Converter (Shield WiFi ESP8266) διευκολύνει τη σύνδεση του Arduino σε δίκτυα WiFi μέσω του ESP8266. Όταν το χρησιμοποιείτε, δεν είναι πλέον απαραίτητο να τοποθετήσετε ένα κύκλωμα με πολλά εξαρτήματα και καλώδια για τη διασύνδεση ενός ESP8266 στο Arduino, απλώς συνδέστε την πλακέτα στο Arduino, τοποθετήστε τον διακόπτη DIP σύμφωνα με τον τρόπο λειτουργίας του shield και προγραμματίστε το Arduino και συνδεθείτε σε δίκτυα WiFi. Επιπλέον, η πλακέτα μπορεί να χρησιμοποιηθεί χωρίς το Arduino, καθώς διαθέτει όλο το pin-out του ESP-12E.

ΠΕΡΙΓΡΑΦΗ

The ESP8266 ESP-12E UART Wireless WIFI Shield TTL Converter (Shield WiFi ESP8266) makes it easy to connect the Arduino to WiFi networks through the ESP8266. When using it, it is no longer necessary to mount a circuit with several components and wires to interconnect an ESP8266 to the Arduino, simply attach the board to the Arduino, position the DIP switch path according to the shield operating mode and program the Arduino to connect to WiFi networks. In addition, the board can be used without the Arduino, as it has all the pin-outs of the ESP-12E available.

  • A (DIGITAL PINS): sequence of pins used by the Arduino.
  • B (ESP8266 PINS): ESP8266-12E and their respective pins. On the back of the plate there is the nomenclature of the pins.
  • C (EXTERNAL SERIAL USB ADAPTER CONNECTION): Pin sequence used to connect the external Serial USB adapter for firmware update or debugging of the ESP8266.
  • D (SHIELD MAINTENANCE PINS): A three-pin sequence identified as Maintenance Only and used to verify that the voltage regulator is receiving and supplying the voltages correctly. IT SHOULD NOT BE USED AS A SUPPLY SOURCE.
  • E (DIP SWITCH TO MODIFY OPERATING MODES): Four-way DIP switch to change operating modes.
  • CONTACT 1 (P1) and CONTACT 2 (P2): used to connect the RX (represented by P1) and TX (represented by P2) of the ESP8266 to the Arduino D0 (RX) and D1 (TX) pins. P1 and P2 in OFF position disable the RX connection from ESP8266 to Arduino TX and TX from ESP8266 to Arduino RX.
  • CONTACT 3 (P3) and CONTACT 4 (P4): used to enable and disable the firmware upgrade mode for ESP8266. To enable firmware write / load on ESP8266, P3 and P4 must be in the ON position. When P4 is in the ON position, the DFU LED will light, indicating that the ESP8266 is enabled to receive the firmware. To disable the firmware update mode and set the ESP8266 to normal operation, simply set P3 and P4 to OFF.
    NOTE: All 4 contacts in the OFF position indicate that the ESP8266 is operating in normal mode next to the Arduino.
  • F (AD8 FROM ESP8266): pin assignment for the ESP8266 ADC. A pin operating in the range of 0 to 1V and another pin operating in the range of 0 to 3.3V. These pins will only be used when using ESP8266 alone (standalone mode).
  • G (ESP8266 RESET): button used to reset ESP8266. Whenever you change the position of the DIP switches, you must press the ESP-RST button.
  • H (ANALOG PIN AND POWER SUPPLY): sequence of pins used by the Arduino.
    This shield has a peculiarity in the contacts P1 and P2 of the DIP Switch and this particularity, in fact it generates a great doubt in the people who try to use the shield.
    According to the shield's creator, when connecting it to the Arduino only 2 pins will be required. These pins would be D0 and D1 (Arduino's RX and TX respectively) and in addition, the DIP Switch's P1 and P2 contacts on the shield must be in the ON position for the connection.

ΕΠΙΠΛΕΟΝ ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ

  • 32-bit RISC architecture
  • Processor can operate at 80MHz / 160MHz
  • 32MB flash memory
  • 64kB for instructions
  • 96kB for data
  • Standard native WiFi 802.11b / g / n
  • Operates in AP, Station or AP + Station mode
  • It has 11 digital pins
  • It has 1 analog pin with 10-bit resolution
  • Digital pins except the D0 have interrupt, PWM, I2C and one wire
  • Programmable through USB or WiFi (OTA)
  • Compatible with Arduino IDE
  • Compatible with modules and sensors used in Arduino

ΔΥΝΑΤΟΤΗΤΕΣ

  • Size of the Arduino Uno R3 and the pinning is compatible with Arduino Uno, Mega 2560, Leonardo and derivatives.
  • Minor versions of the Arduino (Nano and Pro Mini, for example) are compatible, but connections must be made through jumpers.
  • Arduino voltage (5V) is used to power the shield.
  • Has AMS1117 3.3V voltage regulator, so the 5V voltage supplied by the Arduino is reduced to power the shield without the need for external power.
  • It has built-in logic level converter, so the Arduino TTL level (5V) does not damage the ESP8266 that operates with TTL 3.3V level.
  • It has a 4-way DIP switch that serves to change the operating modes of the board.- Available operating modes: WiFi Shield for Arduino / sending AT commands through Arduino / firmware upgrade through USB Serial external / standalone converter.
  • It has indicative LEDs (PWR / DFU / AP / STA).
  • Because it is in shield format, it allows other shields and modules to be inserted.
  • It has the ESP-RST button to reset the ESP8266.
  • The ESP8266 ADC pin is available in two forms on the board, the first on a pin with 0 to 1V reading range and the second form in the 0 to 3.3V range.
