Texas Instruments CC3200 WiFi SensorTag is Now Available for $40

Texas Instruments launched SensorTag in 2013, and at the time there was just a Bluetooth 4.0 LE version with 6 different sensors. I bought one for $25 at the time, and tried it with a Raspberry Pi board and a BLE USB dongle. Since then, the company has launched a new multi standard model (CC2650STK) supporting Buetooth low energy, 6LoWPAN, and ZigBee, and has just started to take orders for CC3200 WiFi SensorTag for $39.99, which seems expensive in a world of $2 ESP8266 modules. But let’s see what the kit has to offer: Wireless MCU – Texas Instruments CC3200 SimpleLink ARM Cortex-M4 MCU @ up to 80 MHz, with up to 256KB RAM, Hardware Crypto Engine, DMA engine Storage – 1 MB serial flash memory Connectivity – 802.11 b/g/n WiFi with on-board inverted-F antenna with RF connector for conducted testing Sensors – Gyroscope, accelerometer, compass, light sensor (OPT3001), humidity […]

Orange Pi Brick is a $1 Raspberry Pi Zero Compatible Smart Block

Shenzhen Xunlong Orange Pi boards are popular with some developers and hobbyists thanks to their low price, but the company is also aware that some are critical of their products. Some of the complaints include that their boards are too difficult to use due to lack of proper firmware and documentation, they are called “Orange Pi”, but aren’t even made with orange color, with some people even going as far as saying their boards are just bricks just good enough to collect dust. The company has taken all remarks into consideration, and has come up with a product that’s simple to use and orange, while breaking the price barrier, as it will be sold for just $1. Yep. You read that right. One Dollar. I’ve worked with the company to get the exclusive, believe me you won’t find this on any other sites, and they’ve sent me an early sample. […]

Getting Started with Wemos D1 mini ESP8266 Board, DHT & Relay Shields

Wemos D1 mini is an ESP8266 board that’s interesting thanks to its size, its low price ($4), micro USB power, its shields, and a documentation that looks fairly good. The board can be programmed with Arduino or Lua, and supports both serial and OTA programming. I’ve decided to give it a try and bought the board together with two temperature shields, a relay shield, and micro SD shield. I got all for $ 14.00 from Wemos Aliexpress shop, and it took about one month for delivery. I can also see they’ve recently released a new OLED shield selling for about $5. All shields were shipped inside their own anti-static bags. The pins are clearly marked on both side of the board and the shields. One side of the board features ESP8266 module. and the other side has CH340 serial to USB chip, and the reset button. The provided headers make […]

$4 Wemos D1 mini ESP8266 Board Supports Shields with a Temperature Sensor, a Button, a Relay, or a micro SD slot

Wemos D1 board, a $9 ESP8266 board in Arduino UNO form factor, now has a little brother with Wemos D1 mini. The board looks somewhat similar to NodeMCU with breadboard friendly I/Os on the sides and a micro USB port for power and programming, but what could make it more interesting, beside the $4 price tag, is that the company also developed several shields (aka add-on boards). Wemos D1 mini specifications: WiFi 802.11 b/g/n module based on ESP8266EX with 4MB flash Expansion – Through holes with 11x digital input/output pins (3.3V) supporting interrupt/PWM/I2C/one-wire (except D0) 1x analog input (3.3V max input) Reset and power signals (5V, 3.3V, GND) USB – micro USB port Misc – Reset button Power – 5V via micro USB or 5V pin Dimensions – 34.2 x 25.6 mm Weight – 10 grams The board is said to be compatible with Arduino IDE and NodeMCU firmware. ESP8266 […]

96Boards Mezzanine Add-on Boards with Sensors, Buttons, Relays, etc.. Are Starting to Show Up

Beside excellent software support, and a great community, the two most popular maker boards on the market, namely Arduino and Raspberry Pi, also have many add-on boards, respectively called Shields and Hats, to expand their user and connect sensors, buttons, displays, and so on… Several Linaro’s 96Boards compliant development board launched last year such as LeMaker Hikey and DragonBoard 410c with support for recent versions of Android and Debian, and recently three Mezzanine add-ons boards, as well as somewhat pricey USB to TLL debug board, have started to show up to make it an even more interesting platform. Linker mezzanine card starter kit for 96Boards The first kit is made by LinkSprite and includes Linker Base Mezzanine Card with several sensors and cables. Eight 4-pin connectors with ADC, UART, I2C, and GPIOs allow you connect the eight sensors ad modules provided with the kit:a button module, a red LED module, […]

Intel Unveils Three New Micro-controllers for IoT: Quark D1000, Quark D2000, and Quark SE

Intel’s subsidiary, Wind River, has recently announced two operating systems for the Internet of things with Rocket RTOS and Pulsar Linux supported respectively by Quark MCUs, and Intel Atom processors, as well as some ARM SoCs. But it’s not the only “IoT” announcement made by Intel in the last week, as I found out via EETimes that the company also unveiled three new Quark SoCs, namely Quark D1000, and Quark D2000, and Quark SE. Intel Quark D1000 Contrary to previous Quark processor and the upcoming D2000 and SE processors, D1000 is not compatible with x86 instructions set, and features the following: 32-bit Harvard CISC CPU @ 33 MHz with single cycle barrel shifter, two cycle multiplier, multi-cycle divider, integrated 32-bit timer, programmable interrupt controller, and JTAG debugger. 128-bit wide 32 kB code flash and 8 kB ROM 32-bit wide 8 kB SRAM and 4 kB data flash Osciallators 20-33 MHz […]
