SIM7020E 4G NB-IoT Mini Development Board Sells for Just $14

We now have plenty to choose from when it comes to NB-IoT development boards or shields, but so far pricing has not been very attractive, and the cheapest NB-IoT solution I found so far was probably Dragino NB-IoT Bee, a XBee compatible board going for $23. But this morning, I saw an even cheaper NB-IoT board with SIM7020E 4G NB-IOT Mini development board selling for $14.30 on Electrodragon. Not quite the price of 2G solutions, but we’re getting there. Board specifications: NB-IoT Module – SIMCom SIM7020E module working globally with B1/B3/B5/B8/B20/B28 bands supported Nano SIM card holder and u.FL connector for NB-IoT Expansion – 9-pin unpopulated 2.54mm pitch header with 2x UART (3.3V / 5V), ADC, Boot, 3.3V, 5V and GND USB – 1x micro USB port that can be recognized by PC, but as Electrodragon puts it: “not sure how to use it”. Misc – Net LED, power key […]

ESP8266 RGB LED Strip Control with ANAVI Light Controller, Arduino, MQTT, and HTML5

Anavi-Light-Controller-Starter-Kit-Assembly

A few months ago I reviewed ANAVI Light pHat for Raspberry Pi which allows you to control an LED RGB strip from the popular development board. However, if all you need is to switch the RGB LED light on and off, or change the color, the hardware is clearly overpowered for the tasks. So Leon ANAVI designed another board based on ESP8266 – ANAVI Light Controller – which does the same thing with lower cost and more power efficient hardware. Leon sent me a sample for review, so let’s see what we’ve got. ANAVI Light Controller Starter Kit Unboxing I received a package for the Starter kit that’s offered for $39 on CrowdSupply. We’ve got the main board, a USB debugging, an acrylic enclosure with screws and spacers, a one meter RGB LED strip, and some stickers inside the package. If we have a close look at the board we […]

Tibbo-Pi is a Wirefree Modular IoT Prototyping Platform for Raspberry Pi Board

Tibbo Project System (TPS) is a modular Linux IoT prototyping platform based on the same Texas Instruments Sitara AM335x processor used in BeagleBone Black or a PocketBeagle boards, and comprised of a main board, Tibbit blocks to add features as needed, and an enclosure. I’ve now been informed the company will be at Computex 2018 to showcase their new products including Tibbo-Pi, following the same concept as Tibbo Project System, but leveraging Raspberry Pi 3 board and ecosystem instead. While an English brochure is said to be available, all information in the webpage listed in the photo above is in Japanese. But basically, Tibbo-Pi is said to be an IoT edge device for industrial use, made for build a prototypes, or small scale production system thanks to a choice a 60 different Tibbit Blocks sensor and I/O module blocks, all wire free. Programming of the system is typically done with with […]
