RFID Reader/Writer, NFC module, MFRC522
This RFID module based on MFRC522 IC can read and write MIFARE tags. The microcontroller and card reader uses either SPI or I2C for communication. The card reader operates at 13.56MHz.
This module supports MF1xxS20, MF1xxS70 and MF1xxS50 tags. It also supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBs in both directions.
The physical design is compact and have small size at 36x36mm only. 3.3V and 5V power supplies are both possible. This makes it easy for connecting to a board with 5V, no need for 3.3V power regulator.
The antenna is built into the board, and has good sensitivity up to a height of 25mm.
*Note: tags not included.
2pcs Wireless Module NRF24L01, 2.4 Ghz RF transceiver, SPI + 2pcs Socket Adapter
The nRF24L01 wireless module is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver for the 2.4GHz ISM (Industrial, Scientific and Medical) band.
2 pieces: one for Transmitter (Tx) and one for Receiver (Rx).
With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01 provides a true ULP solution enabling months to years of battery lifetime when running on coin cells or AA/AAA batteries.
The Enhanced ShockBurst™ hardware protocol accelerator additionally offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.
The nRF24L01 chip integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost ±60ppm crystal, matching circuitry, and antenna.
WIFI module ESP8266, ESP-01 8Mb
The ESP8266 ESP-01 module is a Wi-Fi module that allows microcontrollers (like Arduino) to access a Wi-Fi network.
This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller (but you still can) to manipulate inputs and outputs as you would normally do with an Arduino, for example, because the ESP-01 acts as a small computer.
Depending on the version of the ESP8266, it is possible to have up to 9 GPIOs (General Purpose Input Output). Then, we can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or we can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well. This makes the ESP8266 very versatile, and it can save you on cost and space in your projects.
