The ESP 01 ESP8266 Serial WIFI Wireless Transceiver Module is a self-contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.

Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that’s just out of the box)! The ESP8266 module is an extremely cost-effective board with a huge, and ever-growing, community.

This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application-specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, which is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions and requires no external RF parts.

There is an almost limitless fountain of information available for the ESP8266, all of which has been provided by amazing community support. In the useful links section below you will find many resources to aid you in using the ESP8266, even instructions on how to transforming this module into an IoT (Internet of Things) solution!

Note:

1. The ESP8266 Module is not capable of 5-3V logic shifting and will require an external Logic Level Converter. Please do not power it directly from your 5V dev board.
2. This new version of the ESP8266 WiFi Module has increased the flash disk size from 512k to 1MB.

Features :

1. Wi-Fi Direct (P2P), soft-AP
2. Integrated TCP/IP protocol stack
3. It features an integrated TR switch, balun, LNA, power amplifier and matching network
4. Equips integrated PLL, regulators, DCXO and power management units
5. Integrated low power 32-bit CPU could be used as an application processor
6. SDIO 1.1 / 2.0, SPI, UART
7. STBC, 1×1 MIMO, 2×1 MIMO
8. A-MPDU & A-MSDU aggregation & 0.4ms guard interval
9. Wake up and transmit packets in < 2ms
10. Standby power consumption of < 1.0mW (DTIM3)

This is FS1000A 433mHz Tx RF Radio Module. This RF module comprises an RF Transmitter and an RF Receiver. The transmitter/receiver (Tx/Rx) pair operates at a frequency of 433 MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.

The transmission occurs at the rate of 1Kbps – 10Kbps. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.

This low-cost RF transmitter can be used to transmit signals up to 100 meters (the antenna design, working environment, and supply voltage will seriously impact the effective distance). It’s good for a short distance, battery power device development. 433 MHz is the operating frequency for transmitter and receiver pair.
