Silicognition ManT1S ESP32 board supports T1S single-pair Ethernet for robotics and automation (Crowdfunding)

Silicognition ManT1S is an ESP32 board with a 4-pole terminal block for T1S single-pair Ethernet (SPE) communication and daisy-chaining, as well as unpopulated headers for GPIOs and programming, and a Qwicc connector for I2C expansion. The IEEE 802.3cg 10BASE-T1S networking standard enables engineers and users to easily network and distribute power to up to eight T1S nodes over a single pair of wires, which makes it suitable for robotics, industrial/home automation, and other projects that benefit from a reduction in the number of cables and associated weight. The company also designed the ManT1S Bridge to interface a standard Ethernet RJ45 to a single-pair T1S mixing segment. ManT1S specifications: System-in-Package – ESP32-PICO-V3-O2 SoC – ESP32 CPU – Xtensa dual-core 32-bit LX6 microprocessor up to 240 MHz Memory – 520B SRAM Storage – 448 KB ROM Wireless – WiFi 4 and Bluetooth 4.2/5.x Memory – 2 MB PSRAM Storage – 8 MB […]

XIAO Smart IR Mate Review – A compact smart infrared remote control hub for Home Assistant

SeeedStudio XIAO IR Test3 AirCon Mitsubishi Slim

SeeedStudio sent us a tiny Smart IR Remote hub for review: XIAO Smart IR Mate, or XIAO IR Mate for short. At first glance, it looks like any other WiFi IR blasters, but what makes it interesting is that the device is built on an open architecture using the XIAO ESP32C3 module and runs on ESPHome, working natively with the Home Assistant open-source home automation platform. As usual, SeeedStudio gives access to the source code, so it’s super convenient if you want to tweak the functions yourself to fit various needs. For those who are new to Smart IR, it’s a device that acts as an infrared (IR) control hub. The idea is to let you control legacy IR-based devices (old TVs, air conditioners, stereos, etc.) via a Smart Home system. We did several tests with several devices we had lying around, namely a Hatari oscillating fan, a Dyson blade-less […]

Baguette S3 ESP32-S3 board gets the breadboard-friendly crown

We often write about breadboard-friendly boards, which typically means they plug nicely into a breadboard, but usually leave only one or two rows to play with on each side. So far, the best option we have come across is probably the Raspberry Breadstick, which is designed for full-length breadboards, but is limited by the I/Os on the Raspberry Pi RP2040 MCU. When it comes to breadboard friendliness, it’s hard to beat The Pi Hut’s Baguette S3, as it provides a single 30-pin header designed to be inserted in one of the rows of a breadboard, leaving plenty of space for prototyping. The board also features an ESP32-S3 microcontroller, a microSD card slot, a USB-C for power and programming, a Qwiic port for further expansion, an RGB LED, and RESET and BOOT buttons. Baguette S3 specifications: Wireless module – ESP32-S3-MINI-1-N8 module SoC – ESP32-S3 dual-core Xtensa LX7 processor with WiFi 4 […]

reTerminal E1001/E1002 – ESP32-S3-powered monochrome/color ePaper displays for dashboards, digital signage

reTerminal E1002 7.3-inch color ePaper display

Seeed Studio’s reTerminal E1001 and E1002 are two ePaper displays featuring an ESP32-S3 WiFi and Bluetooth LE wireless microcontroller suitable for dashboards or digital signage applications. The only difference between the two reTerminal E-series displays is that the E1001 features a 7.5-inch monochrome display, while the E1002 integrates a 7.3-inch 6-color ePaper display. Both come with a 2,000 mAh battery offering up to 3 months of battery life, a 32MB SPI flash, a microSD card slot, a microphone and a buzzer, temperature and humidity sensors, an 8-pin GPIO header, and a few buttons and LEDs. reTerminal E1001/E1002 specifications: Wireless SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 8MB PSRAM Storage 32MB SPI flash MicroSD card slot up to 32GB (FAT32 file system only) Display E1001 – 7.5-inch Monochrome ePaper display with 800×480 resolution E1002 – 7.3-inch “Full Color” (i.e., 6-color) ePaper display with 800×480 resolution Audio Microphone (3) for voice […]

ESPHome 2025.6.0 adds ESP32-P4 and OpenThread support

The ESPHome 2025.6.0 open-source firmware was released on June 18, 2025, with ESP32-P4 support and an initial OpenThread implementation for ESP32-C6 and ESP32-H2 SoCs, thanks to an upgrade to the ESP-IDF framework to version 5.3.2. The developers note that support for ESP32-C6, ESP32-H2, and ESP32-P4 is still being refined, and some components may not yet be fully compatible with these chips, but additional component updates are planned for ESPHome 2025.7.0 next month. That still means that ESPHome devices can connect to Thread networks and communicate with Home Assistant through the Native API as long as you have an OpenThread border router and Thread is enabled in Home Assistant. Users should note some limitations to Thread support: ESPHome does not yet support the Thread “Sleepy End Device” mode Not recommended for applications requiring high-frequency sensor data transmission Best suited for simple control and monitoring use cases Other changes to ESPHome 2025.6.0 […]
