Arduino designed Nano 33 BLE Sense Rev2 board for beginners and entry-level professionals to get familiar with embedded machine learning capabilities. The Arduino Nano 33 BLE Sense Rev2 features Nordic Semiconductor’s nRF52840 microcontroller featuring an Arm Cortex-M4 32-bit...

T-Display-S3 is a development board that has ESP32-S3 as the main control chip. It features a color LCD screen that is 1.9 inches in size and two buttons that may be programmed. The connectivity is made possible by the use of the I8080 interface. It also maintains the same design and...

A compact embedded board from LILYGO with Wi-Fi/BL5.0 and the SIM7080G module for CAT-M and NB-IoT connectivity has been launched recently. The SIM7080G is an SMT-type Multi-Band CAT-M and NB-IoT module. It is easy to add on to because it has many interfaces, such as UART, GPIO, PCM,...

A wide range of uses is possible for low-cost kitchen scales. They are typically quite basic devices without features like wireless connectivity. Still, Liore Shai made the decision to change that by adding Wi-Fi functionality to an Amazon Basics scale which cost about just $10 shipped...

In order to function as a BLE MQ Telemetry Transport (MQTT) gateway and power meter compatible with Home Assistant, Homebridge, OpenHAB, DomoticZ, FHEM, Jeedom, NodeRed, AWS, and any MQTT-compatible IoT or Smart Home system, the Theengs Plug ESP32 smart plug runs OpenMQTTGateway...

Transmission of video from one location to another in the professional video world is typically done via SDI (Serial Digital Interface). This FPGA-powered device, intended as a test tool for SDI circuits, pushes signals at 1.485 Gbps. Based on an Arduino MKR Vidor 4000, Chris Brown of...
