Chips and Modules for IOT

ESP8266 ESP8266 WiFi module is a WiFi serial transceiver module. It implements a full TCP/IP protocol stack and is with a a great computational power providing the ability to manage sensors and for their signals and measurements calculations. These features makes the module compatible for IOT solutions. The module is with a 32-pin QFN package, Integrated RF switch, Integrated RISC processor, I2S interface for high fidelity audio applications, On-chip low-dropout linear regulators for all internal supplies and Wi-Fi Direct (P2P), soft-AP
Bluetooth V4.0 HM-11 BLE Module Bluetooth V4.0 HM-11 BLE Module is based on TI cc2541 chip. The preloaded firmware allow users to quickly build BLE communications via its AT command. The module supports BLE communications with iPhone, iPad (iOS 5.0 or greater) and Android 4.3 or greater. The board is featured with GFSK modulation and with Uart(TTL) communication protocol. This module is identified as the best alternative for HC-05 Bluetooth module.
Microchip MRF24J40MA Microchip MRF24J40MA, a certified 2.4 GHz IEEE 802.15.4 radio transceiver module. It has an integrated PCB antenna, matching circuitry, and supports the ZigBee, MiW and MiWi P2P protocols. It is capable for packet retransmit capable and is surface mountable.
SIM900 SIM900 is an ultra-compact, 24mm x 24mm x 3 mm and reliable wireless module which surface mount type and is a complete Quad-band GSM/GPRS module. The module has a powerful single-chip processor integrating ARM926EJ-S core. the SIM900 delivers GSM/GPRS 850/900/1800/1900MHz performance for voice, SMS, Data, and Fax in a small form factor and with low power consumption.
Semtech LoRa SX1278 Semtech LoRa SX1278 is a low-cost RF front-end transceiver at 433MHZ. The high sensitivity (-136dBm) in LoRa modulation and 20dBm high power output makes the module suitable for low range and low data rate applications. RFIC SX1278 but simplifies the circuit design. The module consists with an antenna port. The module is compatible with Arduino platform and the madule manufactures also provides sample codes based on microcontroller and Arduino platform.

DRF1278F module consists of RFIC SX1278, thin SMD crystal and antenna matching circuit. The antenna port is a standard 50 Ohm impedance. Users don’t need to spend time in RF circuit design and choosing suitable antennas for different applications. DRF1278F operates at 1.8~3.6V with extra low standby current.
