ANAVI Miracle Controller WiFi Board Drives Addressable LED strips (Crowdfunding)

Last year, we wrote a tutorial showing how to control an RGB LED strip Control ANAVI Light ESP8266 controller. The board only works with standard non-addressable 12V LED strips however, and Leon ANAVI received requests to support 5V and 12V addressable LED strips such as NeoPixels, WS2811, WS2812, or TM1804. So he updated ANAVI Light Controller design and has now launched a new open-source hardware certified board based on ESP8266 WiFi chip: ANAVI Miracle Controller. ANAVI Miracle Controller specifications: MCU – Espressif Systems ESP8266 Tensilica L106 32-bit processor Connectivity – Wi-Fi 4 802.11 b/g/n LED Strips Support – Up to two 5V or 12 V addressable LED strips; Supported models include WS2812, WS2812B, WS2811, TM1804, etc. (LED strip chipsets supported by the FastLED library) Expansion 4x I2C header for mini OLED display, sensors, and others 4-pin “GPIO” header with 1x GPIO, GND, 3.3V, and 5V signals Misc – Reset button, […]

NORVII IIoT ESP32 Industrial Controller Comes with Built-in OLED or TFT Display, DIN Rail Mount

We’ve previously covered at least one ESP32 industrial controller with TECHBASE Moduino X equipped with digital and analog I/O terminals, a 0.96″ OLED display, and support for various expansion cards for RS-485, LoRa, Sigfox… beside Ethernet, WiFi, and Bluetooth connectivity offered by the Espressif Systems chip. NORVII IIOT industrial controller – based on ESP32-WROOM-32 module – offers many of the same options as the TECHBASE model, but also integrates a choice of 0.96″ to 1.44″ OLED or TFT display, and comes with plenty of LED’s to ease troubleshooting. There are five variants from three series (AE01, AE02, and AE03) sharing the following specifications: Wireless Module – ESP32-WROOM32 with ESP32 dual-core processor @ 160 MHz, 520 Kbytes SRAM / 4 Mbit Flash, WiFi 802.11 b/g/n Bluetooth 4.2 Storage – Optional microSD card slot Display -Built-in 0.96″ OLED display. 0.96″ TFT display or 1.44″ TFT display Communication – RS-485, WiFi, Bluetooth, optional […]

Trion T20 BGA256 FPGA Development Kit Supports “PulseRain Reindeer” RISC-V RV32IM soft CPU

A few months ago I wrote about FireAnt low-cost FPGA development board powered by Efinix Trion T8 FPGA, and it was the first time I personally heard about the company. Trion FPGA family range from the T4 with 3,888 logic elements up to the Trion T200 with 192,000 LE’s. A board more powerful than FireAnt, but not quite high-end, recently showed up on Digikey with Trion T20 BGA256 development kit going for $150. Trion T20 BGA256 Development Kit specifications: FPGA – Efinix Trion T20 FPGA with 19,728 LE’s, 1,044 Kbit embedded RAM, 36 18×18 multipliers, 7 PPL’s, up to 220 GPIO’s; 256-ball FBGA (13×13 mm) System Memory – 256 Mbit SDR SDRAM Storage – NOR flash USB – 1x Micro-USB port for programming Debug / Configuration – SPI and JTAG headers to facilitate configuration Expansion 3x I/O headers to connect to external devices LVDS TX header, LVDS RX & clock […]

HackEEG Arduino Shield Reads Signals from Your Brain (EEG), Muscles (EMG), and Heart (EKG)

Biosignals Measurements (EEG) Arduino + Raspberry Pi 4

Biosignals are signals from living beings that can be continually measured & monitored, and some common methods to measure those biosignals include electroencephalogram (EEG) to monitor the electrical activity in your brain, electromyography (EMG) for recording the electrical activity produced by skeletal muscles, and electrocardiogram (EKG or ECG) to measure electrical activity of your heartbeat. Those can be used for brain interfaces which according to a recent Ericsson’s report may become commonplace by 2030 with users just thinking about commands, prosthetic arms, health and disease monitoring, and so on. Starcat has designed the HackEEG shield to experiment with all those three methods using an Arduino board and electrodes. HackEEG features and specifications: TI ADS1299 8-Channel, 24-Bit ADC for biopotential measurements SPI EEPROM for storing configuration data 8x analog-digital conversion (ADC) channels, each with a 24x programmable-gain amplifier (PGA). Up to 4x shields can be stacked on one Arduino Due for […]

Moving Your Arduino Project to a Final Product: 8 Useful Tips

This article was written in collaboration with Jonathan Bara from Neoden USA Using Arduino to create your own tailor-made electronics equipment is a preferred method of thousands of electronics manufacturers worldwide, big and small. Arduino projects effectively start at the software to inform the Arduino microprocessor as to what to do, and then from there, move to the prototyping stage. An Arduino prototype is typically a very rough-looking machine whose only main goal is to prove that the concept at play is functional and worthy of refinement. After this stage, thought then goes into how to create a finished product that’s efficient, properly made, and ready for mainstream use. However, it isn’t always extremely easy to know when your prototype should go to the final design stage, or if there are still some kinks to be worked out. To make this process easier, here’s a list of ten tips when […]

YABA is a Backplane Architecture Controller for Automation and IIoT (Crowdfunding)

Automation and IIoT Through YABA YABA is an acronym and a concept being developed. The acronym is Yet Another Backplane Architecture (YABA). The concept is to bridge the gap between PLC/PAC and open source hardware. The YABA Bridge to IoT YABA is designed to be a robust, open hardware controller that will be a simple but effective midpoint or bridge to the approach of modern industrial technologies in the automation and IoT sector, especially production lines in industrial settings. Where YABA is in Process The process is midstage right now, with a prototype coming. There is an IndieGoGo campaign, but it is at the development stage right at this moment. The developer has reported that the team is about two months out of a working prototype, which should put them an efficient schedule timeline. The project has the backplane, CPU, I/O boards at about 75% complete, and just working towards […]

Giveaway Week – WisCellular NB-IoT & eMTC GPS Tracker

Rak Wireless WisCellular is an NB-IoT & eMTC Arduino shield based on Quectel BG96 module with 2G fallback that is similar to the company’s previous-generation WisLTE board, except it is certified for the global markets. I received a beta sample last year and went through the instructions to use it with a Hologram SIM card, but sadly I never managed to make it work, and eventually learned the Hologram SIM card did not support NB-IoT in Thailand. So I would have had to buy a local SIM card, but at the time, they didn’t sell those, and the only way to get an NB-IoT SIM card was to buy a development kit. Before going ahead with the purchase, I asked about coverage in my area but never managed to get a definitive answer so I gave up. So instead of keeping it in a drawer at home, I’d better just […]

The Arduino Pro IDE Targets Professional Developers

It is an underlying fact that Arduino changed or better still evolved the makers, electronics, DIY, open-source, or whatever ecosystem you can think of. It brought the power of creation to the average users irrespective of your current skill set or experiences. Engineers, Scientists, hobbyists, Professors, Makers, and others and have used the ecosystem Arduino has created to build and teach new things. Aside from the fantastic hardware that made all these possible, one of the significant contributors to this easy to use growing community is the IDE. The Arduino IDE is very simplified for newbies to use. Although the Arduino Classic IDE is a pretty decent IDE for building Arduino based projects, it doesn’t offer much for large scale projects or has the tools advance developers needs. I migrated to using Atmel Studio because of what the Arduino IDE was lacking, and others have considered using other IDEs like […]
