WisMesh 1W Booster Starter Kit targets high-power Meshtastic solutions

WisMesh 1W Booster Starter Kit

RAKwireless WisMesh 1W Booster Starter Kit is a high-power Meshtastic solution based on Nordic Semiconductor nRF52840 wireless SoC, Semtech SX1262 RF transceiver, and SKY66122 power amplifier for extended mesh range. It’s built from three modules from the WisBLock IoT ecosystem, and besides a power amplifier for longer Tx range and better penetration through walls, it also features an integrated RF filter for enhanced reception performance. It offers an alternative to the LILYGO T-Beam 1W with an ESP32-S3 + Semtech SX1262 LoRa transceiver +  PA+LNA design, which we covered just last week.

Giveaway Week 2025 winners announced!

CNX Software Giveaway Week 2025 Prizes

CNX Software’s Giveaway Week 2025 has just ended and we’ve now ready to announce the winners. We offered some of the review samples we tested, and three companies joined us offering new samples, namely Banana Pi with two router boards, VOIPAC with an industrial development kit, and RAKwireless offered two of their IoT development kits for the fifth year running. Besides the aforementioned prize, we also included an ESP32-P4 development kit, a dry switch from SONOFF, a Raspberry Pi CM4-based HMI with a 915MHz LoRa module, a 5-inch Raspberry Pi Touch Display, and two USB PD voltage indicators on both CNX Software “International” and CNX Software Thailand. You can see all prizes shown below. Without further ado, here are the seven winners of Giveaway Week 2025 on CNX Software (English): M5Stack M5Tab –  Ed Elecrow Pi Terminal – Tom Banana Pi BPI-R4 Lite router board – Stef 5-inch Raspberry Pi […]

Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

Blues.ONE LTE-M NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]

RAK3112 WisDuo LoRa + WiFi + BLE module targets Edge AI and Meshtastic UI

RAK3112 WisDuo module

RAKwireless “RAK3112 WisDuo Module for Edge AI with LoRa” combines an ESP32-S3 WiFi and BLE SoC with a Semtech SX1262 LoRa transceiver for Edge AI applications and Meshtastic user interfaces. The 3-in-1 LoRa + WiFi  + BLE module is an update to the ESP32-based RAK11200 WisDuo LoRa module, which has limitations in terms of computing power and memory. Those became apparent in more demanding applications such as Edge AI or complex mesh networks. With 16MB of flash and 8MB of PSRAM and a more powerful ESP32-S3 microcontroller, the RAK3112 WisDuo module overcomes those limitations for camera and audio processing, as well as mesh networks like Meshtastic. It also offers a more powerful alternative to the pin-compatible RAK11160 STM32 + ESP32-C2 module that’s better suited for battery-powered sensors. RAKwireless RAK3112 specifications: Main MCU – Espressif Systems ESP32-S3 CPU – Xtensa 32-bit LX7 dual-core CPU @ 240 MHz with vector instructions, AI […]

MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging

MeshCore LoRa off-grid messaging

While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet. The project’s GitHub repository provides some high-level differences compared to the Meshtastic and Reticulum projects: MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable. MeshCore key features: Multi-hop […]

WisMesh Board ONE allows you to build a custom Meshtastic Node with OLED, GPS, battery, enclosure, and more

WisMesh Board ONE Pocket

There are now plenty of Meshtastic hardware platforms for off-grid messaging, audio communication, and GPS coordinate sharing, be it boards or modules for DIY projects, or complete solutions with battery and enclosure working out of the box, such as the Wio Tracker L1 Pro or ThinkNode M2, among many others. In some ways, RAKwireless’ WisMesh Board ONE baseboard offers the best of both worlds, combining the flexibility of DIY designs with the convenience of complete solutions, as it allows users to create a custom Meshtastic node with optional OLED, GPS, battery, antennas, and enclosure besides the usual choice between 868 MHz and 915 MHz LoRa radios. WisMesh Board ONE specifications: Wisblock RAK4631 Module pre-flashed with the Meshtastic firmware SoC – Nordic Semi nRF52840 Core – 32-bit Arm Cortex-M4F CPU @ 64 MHz Memory – 256 KB SRAM Storage – 1 MB Flash Wireless – Bluetooth LE LoRa Transceiver – Semtech […]

RAKwireless Raspberry Pi CM4-based industrial gateway supports both MIOTY and LoRaWAN

WisGate Connect for MIOTY LoRaWAN gateway

The WisGate Connect for MIOTY is an industrial-grade hybrid IoT gateway with support for both MIOTY and LoRaWAN protocols. Built around the RAK7391 carrier board for Raspberry Pi CM4, it is designed for long-range IoT applications, including intelligent street lighting, waste management, environmental monitoring, and traffic flow control. In addition to dual-protocol (MIOTY and LoRaWAN) support, it features USB 2.0, USB 3.0, and a USB-C port for flashing, an HDMI output, and a UART header for debugging. Backhaul options include Wi-Fi, Ethernet, or an optional 4G LTE module. The gateway can be powered in two ways: a wide input voltage DC jack or terminal block, or optional PoE+. We first wrote about the MIOTY Standard back in April 2020. After that, in September 2021, we saw Silicon Labs introduce EFR32FG23 (FG23) and EFR32ZG23 (ZG23) SoCs with MIOTY support, but it’s been a while since we’ve covered products built around this standard.
