LILYGO T-Circle-S3 – An ESP32-S3 devkit with 0.75-inch circular touch display, microphone and speaker

LILYGO T-Circle-S3

The LILYGO T-Circle-S3 is a circular touch display development board built around the ESP32-S3 MCU and designed for smart gadgets, IoT devices, and wearable applications. The board integrates Wi-Fi 4, Bluetooth 5.0, a MEMS microphone, a 3W Class-D audio amplifier with speaker support, an RGB LED, six rear GPIO pins, a Qwiic interface, and USB-C for charging. The board is very similar to the Waveshare RP2350-LCD-1.28, with its round display design, but it does not support wireless connectivity and audio. It also resembles SB Components’ Dual Roundy (ESP32-S3),  but compared to that, the T-Circle-S3 is smaller and features a touch display, a microphone, a speaker amplifier, and an RGB LED. LILYGO T-Circle-S3 specifications: Wireless SoC – ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instruction Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM Wireless – 2.4 GHz WiFi 4 and Bluetooth LE Storage […]

Waveshare ESP32 P4 ETH Edge AI dev baord with ESP32 P4 and Ethernet

Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support, which looks very similar to the Olimex ESP32-P4-DevKit minus the pUEXT connector. However, we’ve also covered other ESP32-P4 boards with Ethernet (and other features) such as the ESP32-P4-Module-DEV-KIT, the ESP32-P4-NANO board, and the GUITION JC-ESP32P4-M3-DEV. Design wise, the board also looks very similar to the Wiznet boards based on Raspberry Pi RP2xxx microcontroller such as the W55RP20-EVB-Pico, the W6300-EVB-Pico2, and the W5100S-EVB-Pico2 boards, but you can also run multimedia workloads with MIPI camera and display interfaces, hardware video encoding, audio processing, AI speech functions, and advanced security features on the ESP32-P4-ETH board. Waveshare ESP32-P4-ETH specifications: SoC – Espressif Systems ESP32-P4 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz Memory 768 KB HP L2MEM (for dual-core CPU), 32 […]

Low-cost mobile robot and security camera monitors your home and pets

OEM Security camera robot

You might have already seen commercial security robots patrolling public spaces, but there’s now something similar, albeit much smaller, for home users: a low-cost OEM “Intelligent Mobile Monitoring Robot”, sometimes sold as the “Blinky Bot”. It’s essentially a battery-powered, two-lens Full-HD PTZ security camera mounted on a robot chassis with track wheels, allowing it to roam the house or a specific room. It supports microSD cards and cloud storage, features WiFi for remote control and two-way calling, and implements AI-powered motion detection and notifications. “Intelligent Mobile Monitoring Robot” key features and specifications: Storage – 32GB to 256GB microSD card and cloud storage Camera Dual-lens “wide-angle” (87°) design with 2MP/1080p resolution PTZ (Pan-Tilt-Zoom) – 360° horizontal and 90° vertical rotation HD night vision H.265 video encoding Audio – Two-way call enabled Connectivity – 2.4 GHz WiFi AI features Pet interaction – Automatic pet behavior tracking, “one-touch voice commands”, built-in laser AI-powered motion […]

Hengbot Sirius is a trainable AI robotic dog for consumers and developers (Crowdfunding)

Henbot Sirius trainable AI robot dog

Hengbot Sirius is a small AI robotic dog that can be trained by users with “manual teaching” and by developers using tools such as Sirius Creator Studio Pro and C or Python APIs. Features include an 8MP camera, a dual-mic array, and a speaker for user interaction using LLMs, text-to-speech, voice recognition, and computer vision leveraging the built-in 5 TOPS AI accelerator, a small LCD, a few RGB LEDs and sensors, and 14 DoF for legs and the head. We’ve seen plenty of other robot dogs over the years, such as the Hiwonder MechDog, the Raspberry Pi CM4-based CM4 XGO Lite smart robot dog, Mini Pupper 2, and Petoi Bittle, among others. Most are more robot-like than dog-like, and the Sirius has a more appealing design closer to a real dog. Hengbot Sirius specifications: SoC – Unnamed but likely Horizon Robotics Sunrise X3 CPU – Quad-core Arm Cortex-A53 @ 1.2-1.5 […]
