Modules for data exchange with a wi-fi network, a Bluetooth communication on a certain frequency. There is a destiny in the projects with Arduino plates, etc. communication Modules can serve several channels at once.
Radio module 433 MHz RFM95 long range (Long Range, Laura). Allows data transmission at distance up to 500 m using a piece of wire as an antenna. Also has a Jack.FL for additional antenna. The kit includes a cable adapted to overlay Seeedstudio Base Shield v2.0.
The module is based on ESP8266. It has the ability to connect to wi-fi and 3 digital ports of input/output, 1 analog input, as well as popular network interfaces: UART and I2C. This version works with a voltage of 3.3 V, it has a microUSB connector for programming, for example, by using the Arduino IDE.
Bluetooth dual mode module from Grove, working in the v4.0 and BLE. It works with a supply voltage of 3.3 V and 5 V. It supports GFSK modulation. The module cooperating with the microcontroller via the UART interface and AT commands.
Module from the Grove series, allowing to connect via Blootooth v2.0 + EDR, class 2. It works with a voltage of 5 V, it communicates through the Grove standard slot, it supports the AT commands. The maximum transmitter power of + 4 dBm, sensitivity - 80 dBm. The module is based on a CSR Bluecore 04 with CMOS technology and AFH.
The module is based on ESP8266. It has the ability to connect to Wi-Fi and 1 digital port of inputs/outputs and 1 analog input and interfaces: UART, I2C. This version works with a voltage of 3.3 V, it has a microUSB connector to power the device. For programming, for example, by using the Arduino IDE, reqiured is USB-UART converter.
Set from Grove including the transmitter and receiver that communicate with each other at a frequency of 433 MHz. It works with voltage of 5 V. Supports the ASK modulation. The modules operate with the microcontroller by using a single-wire interface.
Grove Wi-Fi module based on a ESP8285 system with built-in TCP/IP and support AT commands. It supports the most popular protection, such as WEP, WPA/WPA2, TKIP, AES and WAPI. It can also work as an Access Point with DHCP or serve as a connection for two other Wi-Fi networks.
GPS module based on the system SIM28. It supports 66 channels, works with a voltage of 3.3 V and 5V, communicates through the UART interface (TX, RX). The kit includes a cable adapted to the Seeedstudio Base Shield v2.0 shield.
