Blink an LED on ESP32 board with Tuya Link SDK

Tuya is an All-in-one IoT Platform that enables the user to build smart IoT solutions by connecting devices efficiently, securely, and reliably. This is a getting started article to set up the Tuya platform with the Espressif’s ESP32 boards via tuya link SDK. Further, we use it to control an LED through an Android device. When the switch in the Tuya Smart App is turned ON, the LED connected to the ESP32 board glows and vice versa. Prerequisites Hardware: ESP32 board LED with suitable ballast resistor Breadboard, micro-USB cable, and connecting wires Software: Tuya Account: Tuya IoT Platform (Web) Tuya Account: Tuya Smart Application (Android) Python 3.x Arduino IDE GitHub Link: https://github.com/JayeshRajam/Tuya-ledapp.git Hardware Connections for Tuya Link SDK The ESP32 board is placed on a breadboard. The positive terminal of the LED is connected to digital pin 5 of the ESP32 board and the negative terminal is connected to the […]

Develop USB Host and Device applications with ESP32-S3-USB-OTG board

ESP32-S series chips like ESP32-S2 and ESP32-S3 come with a USB OTG interface, and Espressif unveiled the ESP32-S3-USB-OTG board last September in a post entitled “ESP-USB: Espressif’s Wireless Communication Solution“, where they mostly focused on USB code samples with documentation in Chinese only and provided few details about the board itself. But I browsed the company’s official Aliexpress store earlier this week, and I noticed ESP32-S3-USB-OTG board was up for sale for $35 plus shipping, with additional information now available, so let’s have a closer look. ESP32-S3-USB-OTG board specifications: Wireless module – ESP32-S3-MINI-1-N8 module with ESP32-S3 dual-core Xtensa LX7 processor with WiFi 4 and Bluetooth 5.0 connectivity, 8MB QSPI flash Storage – MicroSD card socket Display – 1.3-inch color LCD USB 1x Full-speed USB host port 1x Full-speed USB slave port 1x Micro USB port for debugging (UART console) Expansion – 14 pads with 6x GPIO, JTAG, 3.3V and GND […]

The cheapest Jasper Lake mini PC so far: JK01 for $140 and up

Intel Jasper Lake N-Series Celeron and Pentium processors were formally introduced at the beginning of the year as the successors of the Gemini Lake (Refresh) processors, and we’ve seen several mini PCs and motherboards so far from lesser-known Chinese manufacturers to more established brands like ASUS, GIGABYTE, and ECS. The previous generation Gemini Lake mini PCs would usually sell around $150 to $200, but now with the JK01 barebone computer, we’ve got an inexpensive Intel Celeron N5095 Jasper Lake mini PC selling for about $141 including shipping. CYX JK01 mini PC specifications: SoC – Intel Celeron N5095 quad-core Jasper Lake  processor @ 2.0GHz /  2.9GHz (Turbo) with 4MB cache, 16EU Intel UHD Graphics; 15W TDP System Memory – 2x SO-DIMM slots for up to 16GB DDR4 memory Storage – M.2 2280 socket for NVMe or SATA SSD, 2.5-inch SATA drive bay, MicroSD card socket Video Output – 1x HDMI 2.0 […]

PicoVoice offline Voice AI engine gets free tier for up to 3 users

PicoVoice offline Voice AI engine has now a free tier that allows people to create custom wake words and voice commands easily for up to three users on any hardware including Raspberry Pi and Arduino boards. I first learned about PicoVoice about a year ago when the offline voice AI engine was showcased on a Raspberry Pi fitted with ReSpeaker 4-mic array to showcase the company’s Porcupine custom wake word engine, and Rhino Speech-to-Intent engine. The demo would support 9 wake words with Alexa, Bumblebee, Computer, Hey Google, Hey Siri, Jarvis, Picovoice, Porcupine, and Terminator. More importantly, the solution allows you to easily create your own custom words in minutes from a web interface by simply typing the selected wake word, with no need for hundreds of voice samples or waiting weeks to get it done. So I tried “Hey You” first, but I was told it was too short, […]

Eigencomm EC616/EC616S SoC supports Cat-NB2 cellular IoT

Eigencomm EC616/EC616S are Cortex-M3 microcontrollers supporting the 3GPP R13/R14 NB-IoT standard, with 3GPP R14 notably introducing the newer LTE Cat-NB2 standard allowing higher bitrates up to 127 kbps downlink, and up to 159 kbps uplink, and OTDOA and E-CID positioning methods. Both EC616 and EC616S are virtually identical, but the EC616S comes with fewer GPIOs and is designed for the lowest possible BoM cost for modules as small as 10×10 mm. Both target similar IoT applications such as wireless meter reading, smoke detection, smart street lights, smart logistics, asset tracking, smart fire monitoring, smart parking, smart home, wearable devices, industry 4.0, smart agriculture, and others. Eigencomm EC616/EC616S specifications: MCU core – Arm Cortex-M3 @ up to 204 MHz Frequency band – 663 MHz to 2200 MHz Protocol version – 3GPP R13/R14 Built-in PA output power – 23dBm Receiver sensitivity – EC616: -118 dBm, EC616S: -117 dBm Peripherals EC616 – 2x […]
