ESP8266 ESP-01 with a shield programmer

Introduction

The ESP8266 ESP-01 is a great device for creating automation & electronics projects with the Internet of Things. In this article, you will get 5 free samples of this board and learn how to build the complete schematic of the electronic project.

This circuit board solves a big problem. See below!

See the ESP-01 printed circuit board presented below.

The ESP8266 ESP-01 requires an external circuit to transfer programming. This circuit consists of 2 buttons: Flash and RESET. See the image presented below.

Shields that are sold on the market do not have these buttons, and this makes it difficult to transfer code to the ESP8266 ESP-01 board.

To solve this problem, we have implemented code transfer buttons and other features to facilitate the creation of device control systems over the internet.

The ESP-01 is connected in socket 2x4 presented in our ESP-01 shield programmer.

The Shield ESP8266 ESP-01 can be used for two purposes:

• Teaching Internet of Things with ESP8266 ESP-01;
• Develop automation solutions with IoT and ESP8266 ESP-01.

Shield ESP8266 ESP01 Programmer and Automation

Below we have the electronic schematic of the shield ESP8266 ESP-01 programmer. It was divided into 9 blocks.

Next, we will begin the discussion of each block in the shield circuit. Initially, we have the power input circuit through a jack connector. The input voltage for the project is from 7V to 9V.

Diode D1 is used to prevent polarity reversal of the source connected to the connector Jack.

After the diode, the input voltage (Vin) is transmitted to the two voltage regulators of the circuit (AMS1117 3V3 and AMS1117 5V), and the pin header is presented below. The pin header is applied to offer Vin voltage for a protoboard.

The voltage regulator capacitors were selected based on the indication of the AMS1117 IC datasheet.

These two voltage levels are used to power the ESP8266 ESP-01 (3V3) and drive the relay coil (5V).

In the circuit, we put an indicator LED to signalize that the circuit is powered, which is presented in the figure below.

After that, we have the circuit to set the ESP8266 ESP-01 to programming and reset mode. This circuit is a big differential on this shield board.

Why is this circuit a great differential in our project?

See the board shown in the figure below.

This board is sold in several stores around the world, but it has a big problem. You need to solder the buttons to set the CHIP ESP8266 ESP-01 to programming mode.

Do you want to buy a card and change the structure when you receive it?

Certainly not! That's why we created our version.

Our version facilitates your programming and creation of your automation projects with the internet of things.

Use the Arduino IDE orother IDE to create your control logic and transfer it to the ESP8266 ESP-01.

How to program the ESP8266 ESP-01?

To do this, you must perform the following steps:

• Connect the USB-SERIAL FTDI232 converter to your computer and to the ICSP Pin Connections bar (Figure 9);
• Check that the LED is on. It is used to indicate that the card is powered;
• Select the COM port of your FTDI232 USB-SERIAL converter;
• Press and hold the FLASH button;
• Press and release the RESET button. After that, you will see the blue ESP LED flash once.

Ready! Your ESP01 is configured to receive a new code. Now, carry out the process of transferring your code through the Arduino IDE.

After transferring the code, you are free to create any programming to control the relay. In the figure below, we have the relay activation circuit.

Finally, the design of the layout of the printed circuit board was carried out...
