UGV Beast – An off-road tracked AI robot built for Raspberry Pi 4/5
Waveshare UGV Beast is an off-road robot with tracked wheels designed for Raspberry Pi 4 or 5 SBC handling AI vision and strategy planning, while an ESP32 sub-controller takes care of motion control and sensor data processing. If the design feels familiar, it's because it's a variant of the UGV Rover unmanned ground vehicle we covered in 2024, which replaces the six wheels of the original model with two continuous tracks, as found in military tanks, for better driving in difficult terrain. Waveshare UGV Beast specifications: Supported SBCs – Raspberry Pi 4B or Raspberry Pi 5 Multi-function driver board/sub-controller Main SoC - ESP32 wireless microcontroller with WiFi, Bluetooth, ESPNOW connectivity Motor drivers - 2x TB6612FNG chips Peripheral interfaces 4x motor control connectors 2x servo connectors Lidar USB (4-pin) and UART (USB-C) connectors 2x 4-pin I2C connectors Sensor - 9-axis attitude sensor (ICM20948) for image stabilization Misc - EN and user

LILYGO T-Watch Ultra – An IP65-rated ESP32-S3 smartwatch with 2.01-inch AMOLED, LoRa, and GNSS
LILYGO T-Watch Ultra – An IP65-rated ESP32-S3 smartwatch with 2.01-inch AMOLED, LoRa, and GNSS
LILYGO's T-Watch Ultra is an ESP32-S3-based smartwatch development platform that appears to be an upgrade over the previous T-Watch-S3 Plus (1.3-inch display and a 940mAh battery), with a larger 2.01-inch AMOLED touch display, a higher-capacity 1,100mAh battery, and an IP65 waterproof and dustproof rating. The device integrates a u-blox MIA-M10Q GNSS module for positioning, a SX1262 LoRa transceiver for long-range communication, and a Bosch BHI260AP smart sensor for motion-based AI applications. Additionally, it features an RTC chip, NFC, a built-in microphone, a haptic driver, a microSD card slot, and a USB Type-C port for programming and charging. The watch targets applications such as Meshtastic nodes, GPS tracking, wearable IoT interfaces, edge AI sensing, and custom smartwatch firmware development. LILYGO T-Watch Ultra specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 512KB SRAM, 8MB PSRAM Wireless – WiFi
WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)
WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)
Hack The Board's WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED. There aren't any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM Storage – TBD Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Display – 1.14-inch TFT display Audio On-board buzzer Built-in microphone for voice and sound detection USB

Trail Mate open-source firmware leverages Meshtastic and MeshCore for ESP32 off-grid handhelds
Trail Mate open-source firmware leverages Meshtastic and MeshCore for ESP32 off-grid handhelds
vicliu624's Trail Mate is an open-source firmware for off-grid communication and GPS coordinates sharing, leveraging the Meshtastic, MeshCore, and other projects, and designed for ESP32 handhelds such as LILYGO's T-LoRa Pager or M5Stack's Tab5 with a LoRaWAN module. The Trail Mate firmware provides a fixed north-up GPS map, direct LoRa text messaging through Meshtastic or MeshCore mesh networks without relying on a smartphone, and prioritizes stability, efficiency, and interoperability over feature density. Trail Mate user interface highlights: Simple main menu with four icons: GPS, LoRa chat, tracker, and system utilities. GPS map Fixed North-Up map orientation (no rotation) Fully offline map rendering from SD card tiles (png/jpg files) Three switchable base layers: OSM / Terrain / Satellite Optional contour overlay for terrain shape awareness Real-time position marker for the current GPS fix Discrete zoom levels optimized for embedded systems Simple breadcrumb trails for path awareness Fast in-page layer switching via
Open-source hardware DAB+ receiver combines ESP32 SoC with Skyworks SI4684 digital radio chip
Open-source hardware DAB+ receiver combines ESP32 SoC with Skyworks SI4684 digital radio chip
When I wrote about a DIY ESP32-S3 internet radio last week, "raspbeguy" commented he'd rather choose an ESP32-based DIY DAB+ receiver kit, such as the one offered by the PE5PVB project based on a Skyworth SI4684 receiver. I first heard about DAB (Digital Audio Broadcast) in 2003 when we considered adding it to a CD player. It's basically the digital equivalent of analog FM/AM radios, and I haven't heard much about it since DAB and the "new" DAB+ standard are mostly a European story (see coverage map below). PE5PVB's open-source hardware DAB receiver might still be worth a look. PE5PVB's SI4684 ESP32 DAB+ receiver features: Controller - ESP32 microcontroller with WiFi and Bluetooth (DoIT ESP32 devkit v1) Storage - MicroSD card slot Display - Color LCD screen with 320x240 resolution (SPI) Audio 2x RCA connectors for speakers 3.5mm headphone jack with amplifier DAB+ receiver - Skyworks SI4684 loaded with DAB+
New release 0.5 of espflasher is now available. Better, faster, and stub support too!
Flash Bee – An ESP32-C3-based DIY handheld lightning detector
Flash Bee – An ESP32-C3-based DIY handheld lightning detector
Flash Bee is an easy-to-make DIY handheld lightning detector based on off-the-shelf parts such as the XIAO ESP32C3 board and the Round Display for XIAO, as well as a 3D-printed enclosure. The design relies on the AMS AS3935 Franklin lightning sensor that's been around for years, and found in kits like Sparkfun's Arduino IoT weather station, which is capable of detecting lightning up to 40 km away with 1km accuracy. While it's not quite new technology, I found the Flash Bee design to be rather cute and convenient, and it looks really easy to reproduce. Flash Bee key components: Seeed Studio XIAO ESP32-C3 with Wi-Fi 4 & Bluetooth LE 5.0 connectivity ($4.90) Round Display for XIAO - 1.28-inch touchscreen display with 240×240 resolution, 65K colors, 100 Hz refresh rate ($18) Grove Lightning Sensor AS3935 ($26.90, alternative link if out of stock) 3.7V 400mAh LiPo battery Slide switch 2x M2 5mm
