Communication

ESP8266 is an IC that delivers a true revolution in the world of makers, especially in the world of IoT (Internet of Things). This is a complete 32-bit SoC (System on Chip) with built-in flash memory, frame and EEPROM which can even be programmed directly from the Arduino interface, without the need for additional micro-controller. With all this, the most important point is that in itself has a built-in WiFi (AP, STA, AP + STA), all that for “little money”.

ESP8266 in this form (ESP-12) is suitable for direct soldering to a printed circuit board as an SMD component or directly solder the wires since the pin has its holes. It also comes with a PCB trace antenna.

Note: ESP8266 is an IC that works at 3.3V! Connecting directly to 5V, or track Arduino or Croduino plate will destroy it! Use logic level converter.

The 433MHz RF Transmitter and Receiver module provides a reliable and cost-effective solution for wireless communication in a wide range of DIY and professional projects. This paired set enables radio frequency (RF) communication between two devices, such as an Arduino, NULA or other microcontrollers, making it perfect for applications requiring remote control or data exchange without physical wiring. Its design ensures stable performance, while the ease of integration allows both beginners and experienced makers to quickly implement wireless functionalities.

Designed with versatility in mind, this RF module operates at a frequency of 433MHz, a widely accepted band for short-range wireless applications. It utilizes ASK (Amplitude Shift Keying) modulation, offering a balance between simplicity and effective data transmission. The module’s flexible voltage requirements for the transmitter (3V – 12V) allow for adjustable range, reaching up to 40 meters indoors and an impressive 100 meters outdoors, especially when paired with an external antenna. This makes it suitable for home automation, security systems, and various Internet of Things (IoT) devices.

Backed by documentation, tutorials and open-source software compatibility (e.g., Arduino RadioHead library), they provide an accessible path for both beginners and experienced developers to add wireless capability to projects.

This logic level converter board module gives us a translation of logic level between two signals. In layman’s terms, if we take a signal with logical “unit” on 5V convert into a signal which logical “unit” has on 3.3V this module will help us. Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would “burn” a device that works on 3.3V and a module gives us to avoid that.
