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.
433 MHz RFM95 radio module of the long range (Long Range: LoRa). It allows for data transmission at the distance of up to 500 m using a piece of wire as an antenna. It also has the u.FL connector for additional antenna. The set includes a cable adapted to 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.
