LILYGO T-ETH-Lite – An ESP32-S3 board with Ethernet, optional PoE support

LILYGO T-ETH-Lite ESP32-S3 is a new ESP32-S3 WiFi and Bluetooth development board with a low-profile Ethernet RJ45 connector using a WIZnet W5500 Ethernet controller, supporting PoE with an extra shield, and also equipped with a microSD card socket and expansion I/Os. ESP32-based development boards with Ethernet have been around for years including LILYGO’s own “TTGO T-Lite W5500“, but so far we haven’t many based on the more recent ESP32-S3 microcontroller except for the SB Components’ ESPi board that we covered last April. But LILYGO T-ETH-Lite ESP32-S3 adds another cost-effective board with Ethernet.

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]

TRACEPaw sensorized paw helps legged robots “feel the floor” with Arduino Nicla Vision

Our four-legged friends don’t walk on tarmac the same way as they do on ice or sand as they can see and feel the floor with their eyes and nerve endings and adapt accordingly. The TRACEPaw open-source project, which stands for “Terrain Recognition And Contact force Estimation through Sensorized Legged Robot Paw“, aims to bring the same capabilities to legged robots. Autonomous Robots Lab achieves this through the Arduino Nicla Vision board leveraging its camera and microphone to run machine learning models on the STM32H7 Cortex-M7 microcontroller in order to determine the type of terrain and estimate the force exercized on the leg. But the camera is apparently not used to look at the terrain, but instead, at the deformation of the silicone hemisphere – made of “Dragon Skin” – at the end of the leg to estimate 3D force vectors, while the microphone is used to recognize terrain types […]
