Kode Dot – An easy-to-use, pocket-sized, battery-powered ESP32-S3 devkit (Crowdfunding)

Kode Dot is a pocket-sized ESP32-S3 maker device for prototyping with a built-in 2.13-inch AMOLED, a 500mAh battery, a 9-axis IMU, a microphone and a speaker, an RTC, a few buttons, a GPIO header, and a magnetic connector for expansion. Kode Dot is designed to simplify the prototyping process. Users can still write code using the Arduino IDE, PlatformIO, or ESP-IDF framework and upload it via the kit’s USB-C port, but thanks to kodeOS firmware, each program becomes a standalone app with its own name, icon, and interface, accessible from the graphical user interface. Kode Dot specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 2.4 GHz Wi-Fi, Bluetooth 5 LE, ESP-NOW peer-to-peer protocol System Memory – 8 MB octal PSRAM Storage 32 MB octal SPI flash microSD card slot Display – 2.13-inch Color AMOLED with 502 x 410 resolution Audio ICS-43434 MEMS microphone 1W MAX98357A speaker amp USB – […]

$200 SpecFive Spectre Pro Android 12 smartphone integrates LoRa Mesh connectivity

Spec5 Spectre Pro LoRa Mesh Android 12 smartphone

LoRa Mesh solutions like Meshtastic or MeshCore enable off-grid messaging, GPS coordinates, and in some cases, audio communication for emergencies, working or hiking in remote areas, or simply to be able to communicate outside of cellular networks. However, adoption is limited, as users need to buy a terminal that costs about the same as an entry-level smartphone, or they may not see any use for it, except for emergencies. Integrating LoRa Mesh into Android smartphones can lower the cost of the feature, since the battery, enclosure, etc… are already there, and you just need to add a LoRa module and an antenna. That’s what SpecFive has done with the SpecFive Spectre Pro 4G LTE smartphone with a LoRa module. The rugged phone runs Android 12 and ships with Meshtastic, Mesh Tic Tac Toe, CheckTastic, and Mesh Chess. Spec5 Spectre Pro specifications: SoC – Unnamed quad-core processor System Memory – 4GB […]

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

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 […]

Blackout Comms Cluster – A pre-configured off-grid LoRa texting and GPS system with cryptographic security

Blackout Comms Off Grid Encrypted Mesh Texting and GPS

Designed by Altware Dev Shop in the US, the Blackout Comms is an off-grid, LoRa-based encrypted mesh communication system built around ESP32 for texting and GPS location sharing without the need for any cellular networks or internet. The device uses asymmetric encryption and digital signatures for secure communication during blackouts, emergencies, or in remote areas where connectivity is unavailable. The device seemed a little bit pricey at first, but the complete kit includes two customized T-Deck communicators and one Altware Link/Node, all pre-configured and ready to use. Each communicator features a DFRobot GPS, Adafruit DS3231 real-time clock, 5000 mAh battery (≈48-hour runtime), external antenna, and PETG printed case, while the Link/Node integrates its own GPS, RTC, 3000 mAh+ battery, and antenna for cluster support. The system forms a private cluster with encrypted, frequency-hopping communication, signed delivery confirmations, and distributed mesh caching. Beyond messaging and location, it also supports proximity/motion sensing […]
