Seeeduino Crypto Board Combines Microchip ATmega4809 MCU and ECC608 Crypto Chip

With the advance of IoT, security has become critical since devices are often connected to the Internet. There are several ways to improve security and one of them is to implement hardware security via crypto chips. One of those chips is Microchip ECC608 (aka ATECC608A) secure element which we previously found in Linux based hardware such as USB Armory MK-II USB Linux computer, and the official Arduino Nano 33 IoT Board. Seeed Studio has now introduced a new Arduino compatible board with Microchip ECC608 crypto chip: Seeeduino Crypto board powered by a Microchip ATmega4809 8-bit AVR MCU. Seeeduino Crypto specifications: MCU – Microchip ATMEGA4809-AFR 8-bit AVR microcontroller @ 16 MHz with 48KB flash, 6,144 Bytes RAM USB – 1x USB Type-C port Expansion Arduino Uno headers with 6x analog inputs, 14x digital I/O pins, 5x PWM 2x I2C Grove headers 1x UART Grove header HW Security – Microchip ECC608 secure […]

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 […]
