Meshtastic Designer helps you build custom Meshtastic solutions with RAKwireless Wisblock components

Meshtastic Designer

RAKWireless introduced the Wisblock IoT Modular System in 2020 to let developers easily create LoRaWAN IoT solutions with various core modules, baseboards, and sensor/IO modules. The company kept adding new Wisblock modules year after year, and there are now over 120 modules part of the Wisblock ecosystem. While the large choice of modules makes designing IoT prototypes more flexible, customers often face challenges in checking compatibility and selecting the right modules for the right slots. That’s why RAKWireless has been working on web-based online designer tools for the Wisblock ecosystem. The first release is the Meshtastic Designer used to quickly configure and create their own Meshtastic devices from the module to enclosure, and place an order from there once the design is complete. I’ve given it a quick try myself. I wanted a Meshtastic device with a display, a keyboard, a GNSS module, and an air quality sensor since the […]

infineon PSOC Control C3 MCU for for Motor Control and Power Conversion

Infineon recently launched the PSOC Control C3x family of Arm Cortex-M33 MCUs for real-time control applications in motor control and power conversion systems. The family includes 18 MCUs categorized into two lines, the Entry Line (C3P2, C3M3) and the Main Line (C3P5, C3M5). These MCUs can be used for various applications including home appliances, industrial drives, robots, light electric vehicles (LEVs), solar systems, and HVAC systems. The Entry Line operates at up to 100 MHz and supports a 12-bit SAR ADC with a sampling rate of up to 6 Msps, making it suitable for basic motor control and power conversion tasks. In contrast, the Main Line offers higher performance with up to 180 MHz operation, a faster 12-bit SAR ADC up to 12 Msps, and 4-channel High-Resolution PWM (HRPWM) for precise control. It also supports Wide Bandgap (WBG) switches for high-frequency power systems. Other features of this MCU include DSPs, FPUs, […]

NXP EdgeLock A30 secure authenticator

NXP recently launched the EdgeLock A30 Secure Authenticator chip, a Common Criteria EAL 6+ certified secure authentication designed for IoT devices, including battery authentication applications. It complies with the EU’s Batteries Regulation 2023/1542, which mandates the inclusion of a Digital Product Passport (DPP), by 2027 to ensure traceability, sustainability, and safety in battery manufacturing and recycling. Alasdair Ross, Senior Director, NFC IoT Security, NXP explains: Secure authentication helps to ensure brand protection, consumer safety, and product traceability, fostering trust and shielding devices from physical damage. Smaller than a grain of rice, the EdgeLock A30 is designed to fit into even the smallest of devices. It supports multiple authentication use cases, making it easier for developers to support a variety of devices and accessories with a single solution, including device to device, cloud to device, counterfeit protection, and storage or protection of device identity. To address these requirements NXP’s EdgeLock A30 […]

Seeed Studio 2-Channel Wi-Fi AC Relay Review – An ESPHome smart switch with power meter function

Seeed Studio 2-Channel Wi-Fi AC Relay Review Home Assistant

We have received the Seeed Studio 2-Channel Wi-Fi AC Relay for review. It is an IoT/Smart Home device featuring a 2-channel relay (wet contact) that operates over a WiFi network, and provides an alternative to SONOFF Smart switches like the SONOFF R2 Dual. The Seeed Studio device is a bit larger and instead of relying on eWelink firmware, it natively supports Home Assistant since it’s pre-installed with ESPHome open-source firmware. Alternatively, if you prefer standalone deployment (without Home Assistant), you can manage it via the web browser. In addition to the basic relay function to control the AC-powered appliances, it also acts as a power meter. This is a good ready-to-use option for Home Assistant enthusiasts who prefer not to assemble their own components. Some practical applications include controlling electrical appliances such as lighting. Let’s dive into the details. Seeed Studio 2-channel AC Wi-Fi Relay unboxing The package we received […]

ESP32 Agent Dev Kit

The ESP32 Agent Dev Kit is an ESP32-S3-powered voice assistant that offers integrations with popular LLM models such as ChatGPT, Gemini, and Claude. Wireless-Tag says the Dev Kit is suitable for “95% of AIoT applications, from smart home devices to desktop toys, robotics, and instruments” In some ways, it is similar to the SenseCAP Watcher, but it has a larger, non-touch display and dual mic input. It however does not support local language models. It also features a standard MikroBUS interface for expansion. For voice capabilities, the ESP32 Dev Kit integrates two onboard, noise-reducing microphones and a high-fidelity speaker. The built-in infrared laser proximity sensor detects human proximity and movement for “smart interactive experiences”. ESP32 Agent Dev Kit specifications: MCU – ESP32-S3 dual-core Tensilica LX7 microcontroller @ 240MHz, 8MB PSRAM Storage – 16MB flash Display – 3.5-inch Touchscreen, 480×360 resolution Camera – 5MP OmniVision OV5647 camera module, 120° field of […]
