For more details, visit the Federal Communications Commission website. You will receive such a certificate if your device meets the requirements. If you need it, you can send it to the lab for testing. Speaking of which, if you designing the antenna yourself, then your device will not be FCC certified. Such as decoupling capacitors, resistors for pull-ups and pull-downs and antenna. For proper operation, several components around the chip are needed. Essential here is the ability to PCB design. Of course, you have to do a lot of work in this solution yourself. If you are designing a hi-end device that must be as small as possible, or if you’ll produce it in large quantities and every penny is important, you should choose this one. The lowest level (it might as well be called the ground floor □ ) it is the ESP8266EX chip itself. Level 1 is the hardest one and Level 3 is the easiest. But don’t get me wrong – these aren’t levels of difficulty □ Actually, it’s the opposite. To somehow reasonably describe what you have to choose, I divided it into three levels. They differ in shape, size, number of pins, type of antenna, and additional elements. All these modules are based on the same ESP8266EX chip. The current list you will find on Wikipedia. There are many modules/boards, and they are continually adding new ones. They have all the necessary components onboard. You can also choose from a whole range of modules or boards witch ESP8266. All you have to do is add an antenna and some passive elements around, and you are ready to go! It integrates antenna switches, RF balun, power amplifier, filters, and power management modules. What makes it unique is self-contained Wi-Fi capabilities. So you can use it like any other microcontroller to control your device. It can run witch a clock speed up to 160 MHz (deaflut is 80 MHz). It has sixteen configurable GPIOs, and build-in most of the popular interfaces like UART, SDIO, SPI, I2C, I2S, GPIO, ADC, PWM. Let’s dive in right away! What is ESP8266?ĮSP8266 is a 32-bit microcontroller with a Tensilica processor, produced by Espressif Systems. You will learn how to connect a UART-USB adapter, and which type of module/board is best for you. In this article, I will tell you how to program the ESP8266 chip, how to configure pins to put it into flash mode. It is the perfect solution for IoT applications and Smart Homes. It can run your device and be connected to a WIFI at the same time. I use it wherever it fits □ For less than $2, you can have a fully functional microcontroller with a full TCP/IP stack.
