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

$15 STM32U575 development board features FPC display connector, microSD card slot, two 48-pin GPIO headers

A few days ago, we looked at the WeAct Studio STM32U585CIU6 development board, which features an ultra-low-power STM32U5 Cortex-M33 MCU and was added to MicroPython v1.28. If you're looking for another STM32U5-based option, especially for compact UI projects, Maker Go now offers an STM32U575 board with a display connector, a microSD card slot, and many more GPIOs While the STM32U585 on the WeAct board features cryptographic accelerators, the STM32U575VGT6 MCU on the Maker Go board is closely related and still offers the same high-performance Cortex-M33 core running at 160 MHz, along with ultra-low-power capabilities. This new board also adds 8MB of external flash and is designed to accept 1.47-inch or 2.0-inch LCDs directly via a ribbon cable. STM32U575VGT6 board specifications: Microcontroller – ST STM32U575VGT6 Core – Arm Cortex-M33 Armv8-M core clocked at up to 160 MHz with FPU, Arm TrustZone Memory – 786 KB SRAM Flash – 1024 KB (1

SN1 Solar Node – An ESP32-C3-based board with IP67 enclosure, solar charging, ESPHome firmware

Designed by Granz Scientific LLC, the SN1 Solar Node is an ESP32-C3-based IoT node/development board designed specifically for off-grid IoT projects. Development boards like Seeed Studio Wio Tracker, or industrial controllers like DFRobot LoRaWAN Control Terminal, allow you to handle your own battery management and weatherproofing, or on the other end, you have products like SenseCAP Solar Node P1 that come with everything integrated but do not allow adding custom hardware. This is where the SN1 Solar Node is different; it features an IP67-rated enclosure with an integrated solar panel on the lid, 18650 battery support, and prototyping strip-board areas for custom circuitry. It also includes a smart power switch that allows the battery to continue charging from the solar panel even when the board is powered off. Additionally, it provides battery voltage monitoring, breaks out most GPIOs for easy access, and includes optional jumpers for an onboard LED and

Entry-level Intel Core 3 304 Wildcat Lake processor details and benchmarks surface

Intel discreetly introduced the Wildcat Lake Core Series 3 CPUs at CES 2026 with some high-level specifications, but no part numbers or exact CPU, GPU, and NPU frequencies. Some leaks reveal more details about the Wildcat Lake parts, notably the Intel Core 3 304 penta-core processor, for which we also have some benchmarks. Intel Wildcat Lake SKUs The data below comes from a post by Jaykihn on X. While we have six SKUs in the table above, the Intel Core 5 320/330 and Core 7 350/360 only differ in terms of SIPP (Intel Stable IT Platform Program) support. SIPP is an enterprise initiative that ensures that key platform components, such as processors, chipsets, graphics, storage, networking, and wireless, remain consistent with minimal or no changes for a guaranteed period. The GPU turbo clocks are much higher than in Alder Lake-N/Twin Lake chips (typically 1 GHz to 1.35 GHz), and LPDDR5x

Timers seem simple until they cause mysterious power drain or timing issues. The JL JieLi AC696N SDK provides two timer systems with different characteristics. Here's what I've learned debugging on the dev board.

Practical Tip
Test both on the AC696N development board. Add serial prints to see which thread the callback runs in.

Both timer systems support one-shot timeouts—choose whichever fits your context needs.
