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

ESP32-S3 Ethernet Board

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. LILYGO T-ETH-Lite ESP32-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps and […]

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

Sparkfun DataLogger IoT

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 […]

Orange Pi Zero 2W – A Raspberry Pi Zero 2W alternative with up to 4GB RAM

Orange Pi Zero 2W

As its name implies the Orange Pi Zero 2W is an alternative to the Raspberry Pi Zero 2W with basically the same features and form factor, but equipped with a slightly more powerful Allwinner H618 quad-core Cortex-A53 clocked at 1.5 GHz, and more RAM options from 1GB to 4GB. The new Orange Pi board comes with a mini HDMI port, two USB-C ports, WiFi 5 and Bluetooth 5.0 wireless module, a microSD card for the OS, a 16MB SPI flash for the bootloader, the usual 40-pin Raspberry Pi GPIO header, and a 24-pin “function” connector used for expansion boards and located where the camera connector is on the Pi Zero 2W. Orange Pi Zero 2W specifications: SoC – Allwinner H618 quad-core Arm Cortex-A53 processor @ up to 1.5GHz with 1MB L2 cache and Arm Mali-G31 MP2 GPU with support for OpenGL ES 1.0/2.0/3.2, OpenCL 2.0, Vulkan 1.1 System Memory – […]

Gateworks GW7400 networking SBC features 6 Gigabit Ethernet ports, M.2 & mini PCIe sockets for wireless connectivity

NXP I.MX 8M Networking SBC 6 Ethernet ports

Gateworks Venice GW7400 is a rugged industrial single board computer for networking and gateway applications with six Gigabit Ethernet ports, and one M.2 and three mini PCIe sockets for WiFi, cellular, and other wireless options. We first mentioned the GW7400 board around three years ago, when the company introduced the Venice family powered by NXP i.MX 8M processor. But the board launched today has a different design with more Ethernet, an NXP i.MX8M Plus AI processor, up to 4GB RAM, up to 64GB eMMC flash, and various interfaces such as USB 3.0, dual CAN Bus, DIO, I2C, SPI, and UART. Gateworks GW7400 specifications: SoC – NXP i.MX 8M Plus CPU – Quad-core Cortex-A53 @ up to 1.6 GHz (industrial-grade) Real-time core – Arm Cortex-M7 @ up to 800 MHz GPU – Vivante GC7000UL 3D GPU, Vivante GC520L 2D GPU VPU – Up to 1080p60 video encoding and decoding AI accelerator […]

ESP32-S3-BOX-3 devkit comes with 2.4-inch display, dual microphone, PCIe expansion connector

ESP32-S3-BOX-3

Espressif Systems has launched an update to their ESP32-S3-Box development kit for online and offline voice assistants with the ESP32-S3-BOX-3 devkit that still features a 2.4-inch capacitive touchscreen display with 320×240 resolution, two microphones, a built-in speaker, and a USB-C port, but replaces the PMOD connector by a PCIe connector for various expansion modules. The open-source ESP32-S3 development kit is powered by the ESP32-S3 SoC with AI extensions and can be used to implement all sorts of solutions using the company’s ESP-SR, ESP RainMaker, and Matter solutions such as an offline voice assistant, a chatbot powered by ChatGPT, a handheld gaming console, a tiny robot, a Matter-compatible Smart Home hub, and more.

SenseCAP T1000 – A credit card-sized LoRaWAN GPS tracker based on Semtech LR1110 (Crowdfunding)

SenseCAP T1000

SenseCAP T1000 is an ultra-thin credit-card-sized GPS tracker with Semtech LR1110 wireless chip with LoRaWAN, WiFi (scanning), and GNSS connectivity, plus two built-in sensors to monitor temperature, light intensity, and motion. We’ve covered several LTE IoT and LoRaWAN GPS trackers in the past and even tested the RAK811 LoRa GPS Tracker board with our own gateway, but the SenseCAP T1000 is particularly attractive due to its slim design. It works both indoors and outdoors with IP65 waterproof protection, looks quite easy to set up with its button and LED, and also integrates an SOS feature that can be triggered with a long press. SenseCAP T1000 specifications: Wireless Semtech LoRa Edge LR1110 Asset Management Platform LoRa/(G)FSK Half-Duplex RF transceiver working in the 150 – 960MHz; compatible with LoRaWAN 1.0.4 standard GNSS (GPS/ BeiDou) low-power scanning 802.11b/g/n Wi-Fi ultra-low-power passive scanning Unnamed Bluetooth 5.1 LE chip for initial configuration and indoor positioning […]

Getting started with VOIPAC IMX8M Industrial development kit (Yocto Linux SDK)

VOIPAC IMX8M Developer Kit Audio Testing

Last month I went through an unboxing of the VOIPAC iMX8M Industrial Development Kit with some specs and a quick try with the pre-loaded Yocto 3.1 Linux image. The kit is quite versatile with plenty of interfaces and headers, and eventually, it will support Android 12 and Ubuntu 22.04 LTS. but in the meantime, I played a bit with the Yocto Linux SDK for the NXP i.MX 8M board and will report by experience getting started with VOIPAC IMX8M Industrial development kit. WiFi antennas installation But before checking out Yocto Linux, I will install the two WiFi antennas since I did not do it last time around. We can attach the SMA connectors to the two metal plates on the side of the board securing them with the provided nuts and spacers. The other side of the antenna’s cable comes with a tiny u.FL (or is it MHF4) connector and […]
