Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right frequency 433 MHz, 865 MHz, 915 MHz or 923 MHz […]

LibreRouter is an Open-Source Hardware Router for Community Networks

Battlemesh (aka the Wireless Battle of the Mesh) is an event that aims at bringing together people from across the world to test the performance of different routing protocols for ad-hoc networks. While BattleMesh v12 took place in Paris in July 2019, I’ve just been informed that presentation videos were now out. There are talks about OpenWrt, mesh networks, and communities, but one talk brought a project I had not looked into details yet. Originated from Argentina, LibreRouter is described as an open-source hardware router designed for community networks that are organized by a group of people such as neighbors in order to share local and other content without a profit motive. LibreRouter LR1 specifications: SoC – Qualcomm Atheros QCA9558 MIPS processor @ 750 MHz System Memory – 128 MB DDR RAM Storage – 16 MB Flash MCU – Microchip ATTiny13 8-bitAVR MCU used as hardware watchdog to handle failed flashes or hardware failures Networking 2x Gigabit Ethernet ports connected […]

FreeMesh WiFi 5 Mesh Network Router Runs OpenWrt

FreeMesh W1326 LTE Router Mesh Network Access FreeMesh has launched an open-source mesh router, the WE1326 LTE FreeMesh Router (included are two nodes) that runs OpenWrt open-source operating system. Open Source and “Hackable” Mesh System FreeMesh enters the mesh market with source code posted on Gitlab, a user-hackable/customizable mesh in other words. FreeMesh uses OpenWrt – the OpenWrt project is a Linux operating system aimed at embedded systems. The focus is on removing the need for a static firmware, where there is only one option for software for the hardware being purchased. The Offerings and Markets The company is targeting the residential market, where most mesh systems are almost double the $150.00 price tag of the FreeMesh. It is reported that there are other ZBT WE826-WD based mesh routers on the market, check out the LinuxGizmos.com article for more information. FreeMesh Specifications FreeMesh Router CPU Dual Core 880MHz MediaTek MT7621AT ROM SPI 16MB RAM DDR3 512MB Antenna 2x 5dBi 2.4GHz, 2x 5dBi 5GHz, 2x […]
