ESP8266 ESP-201 WIFI IOT Module Arduino IDE Compatible Overview

This ESP-201 module is one of the ESP8266 board version. This ESP8266 support both pcb antenna and external antenna.

This ESP-201 module is one of the ESP8266 board version. This ESP8266 support both pcb antenna and external antenna using U.FL connector. ESP-201 comes with Ai-Thinker firmware as they are the 3rd party manufacture of Espressif chip. With a dimension of 25mm x 35mm, this board required de-soldering and soldering modification of middle pins to make sure it is breadboard friendly.

This ESP-201 board is recommended as its offer more pins over ESP-01 with a cheaper price than ESP-12. ESP-201 utilizes ESP8266EX chip by Espressif Systems. ESP8266EX has been designed for mobile, wearable electronics and Internet of Things applications with the aim of achieving the lowest power consumption with a combination of several proprietary techniques. The power saving architecture operates mainly in 3 modes: active mode, sleep mode and deep sleep mode. The major application of this ESP8266EX chip to IoT includes home appliances, home automation, smart lug and lights, mesh network, industrial wireless control, baby monitors, IP cameras, sensor networks, wearable electronics, WiFi location-aware devices, security ID tags and WiFi positioning system beacons.

There are up to 17 GPIO pins.  They can be assigned to various functions by the firmware. Each GPIO can be configured with internal pull-up (except XPD_DCDC, which is configured with internal pulldown), input available for sampling by a software register, input triggering an edge or level CPU interrupt, input triggering a level wakeup interrupt, open-drain or push-pull output driver, or output source from a software register, or a sigma-delta PWM DAC. These pins are multiplexed with other functions such as I2C, I2S, UART and PWM.

ESP8266 ESP-01 WiFi IOT Module Arduino IDE Compatible Overview

ESP8266 is a low cost WiFi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer. ESP-01 is one of ESP8266 version. This WiFi module allow microcontrollers to access WiFi network.

ESP8266 is a low cost WiFi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif system. This chip become widely available when third-party manufacture, Ai-Thinker started the production on August 2014. During that time, most of the documentation is not in english. This chip become famous due to very low price as compared to another WiFi enable module. 

 In late 2014, Espressif released software development kit (SDK) which allow chip to be programmed without the needed of external microcontroller. Since that Espressif has been releasing the latest SDK with two version which is RTOS and NON-OS sdk. Besides that, there are a few another open source SDK instead of the original one. They are NodeMCU (Lua based firmware), Arduino (allow to be programmed as normal Arduino board), and MicroPython (Pyhton for embedded devices).

 ESP-01 is one of ESP8266 version. This WiFi module allow microcontrollers to access WiFi network.

 There are 8 pins available in this ESP-01 including VCC and GND. Only two GPIO available in this ESP-01 series. 
ESP8266 ESP-01 Pinout
ESP8266 is a complete and self-contained WiFi network solutions that can carry software applications or through another application processor. ESP8266 specifically for mobile devices, wearable electronics and networking applications design and make the machine to achieve the lowest energy consumption, together with several other patented technology. This energy-efficient construction in three modes: active mode, sleep mode and deep sleep mode type.

 Below if an overview video of ESP-01.
