Olimex Introduces Open Source Hardware ESP8266 Wi-Fi Modules, Evaluation Board Coming Soon

ESP8266 has become popular as module based on this SoC make it incredibly cheap to add Wi-Fi to all sort of things, the SDK available, and a community has gathered around the solution. Olimex has jumped on the bandwagon, and is now provided two open source hardware ESP8266 modules: MOD-WIFI-ESP8266 which makes it easy to interface to other Olimex boards thanks to its UEXT connector, and MOD-WIFI-ESP8266-DEV with  two rows of 0.1″ connectors and an unsoldered UEXT pad, is better suited if you want to integrate it with your own baseboard, or experiment with a breadboard. An evaluation board called MOD-WIFI-ESP8266-EVB will be launched a little later. Both modules share most specifications: SoC – Espressif Systems ESP8266 32-bit RISC processor with 802.11 b/g/n support(32-pin QFN package), Wi-Fi – 802.112 b/g/n with WEP, TKIP, AES, and WAPI engines, Wi-Fi direct (P2P), and soft-AP.

Semtech LoRa SX1272 RF Module Enables Up to 30 KM Wireless Range for Arduino, Raspberry Pi, Waspmote, and More

Libelium’s Waspmote is a board based on Atmel ATmega1281 MCU that interfaces with over 80 sensors, and various wireless communication modules, and targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. They have some professional kits for over 3,000 Euros including training, but a more affordable Starter Kit is also available for 199 Euros on Cooking Hacks. But I’m not going to cover Waspmote in details today. I just mention it because of an article on embedded.com mentioning compatibility with a Libelium / Semtech LoRa SX1272 RF module delivering up to 30km range in ideal conditions (and usually 22+ km range in LOS), and about 2km range in urban settings. I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option, and it works not only with Waspmote, but also the […]

Add Wi-Fi to Arduino Boards for $3 with ESP8266 Wi-Fi Serial Module

There has been some buzz around ESP8266 Wi-Fi module, mostly because of its low price, and SDK availability, meaning it could become the Wi-Fi equivalent of ENC28J60 Ethernet module, and that for $5 you could potentially add Wi-Fi to your Arduino board for example. Since then, the price has come down even further, and if you are prepared to buy 5 pieces, you can now get the module for less than $3 / piece shipped, alternatively a single module costs $4, and a complete Wi-Fi + Arduino Uno (clone) kit goes for $15. A community has also been built around the chip, and a several project have been made with Arduino boards and ESP8266 module. The best way to find information is to go to ESP8266 community forum, as well as read the Wiki on github. There’s currently a GCC toolchain for Espressif Systems ESP8266, open source tools for working […]

Spark Photon is a $19 Hackable IoT Wi-Fi Board

Spark Core is a popular Wi-Fi module for the internet of things  with a community of over 20,000 developers, but at $39 it may have started to feel a little expensive compared to the new IoT Wi-Fi modules such as ESP82666 or xWiFi, so the company has unveiled a new Wi-Fi board called Photon that’s smaller, better, and cheaper. Let’s compare Spark Core with the new Spark Photon. Feature Spark Core Spark Photon Wi-Fi Support 802.11 b/g 802.11 b/g/n Wi-Fi Setup Smart Config Soft AP Wireless Module TI CC3000 Broadcom BCM43362 MCU STM32F103 STM32F205 MCU Speed 72 MHz 120 MHz Flash Memory 128 KB 1 MB RAM 20 KB 128 KB GPIO 18 UART (Serial) Yes JTAG Yes I2C Yes SPI Yes ADC Yes DAC No Yes CAN No Yes VBAT pin exposed No Yes Wakeup pin exposed No Yes Price $39.00 $19.00 So beside slashing the price by 50%, […]

Connect Objects Wirelessly, and Create User Interfaces Easily With Xped DeB for Arduino (Crowdfunding)

Xped, an australian startup, has designed an ecosystem comprised of an Arduino shield with NFC and 802.15.4 connectivity, a Raspberry Pi Model B+ based gateway, and DeB browser that generates a user interface in Android, iOS, or Linux based on an XML file stored in an Arduino board. This allows to connect various objects wirelessly, with reduced power consumption thanks to 802.15.4, and to create user interfaces easily with a text file located in your Arduino board. ADRC stands for Auto-Discovery Remote Control, and that’s what Xped ADRC Shield allows thanks to the following hardware specifications: MCU – RM Cortex M3 32-bit microcontroller with 256 KB of FLASH memory. NFC – NDEF Type-2 Tag with bi-directional communications capability. NFP proximity communications technology which is similar to NFC but was developed by Xped to use less than 1,000th of the power and provide faster speeds than NFC. It is mainly used […]
