This guide introduces you to some of the most recommended hardware used in the YQLMesh network. It’s not an exhaustive list, but includes reliable, tested options for personal use and repeater setups.
Client vs Repeater Devices
- Client Devices: These are typically small and portable, pairing with a phone or laptop to send and receive messages.
- Repeater Devices: These are designed to run continuously and help carry messages further through the network. They’re often mounted outside, connected to solar or hard wired power with battery backups.
Repeaters play a critical role in expanding coverage and strengthening the overall mesh network.
Recommended Devices
Heltec V3
The Heltec V3 is a compact device with a built-in screen and USB power. Thanks to new firmware updates, it now supports low power consumption, making it suitable for both casual use and as a repeater device.
- Best for: Getting started, testing, or small repeater builds
- Also good for: Mobile or personal mesh use
- Note: Uses USB-C for easy power supply and can now run 24/7 efficiently
Heltec V4
The Heltec V4 is similar to the V3 but built with repeater use in mind. It comes in versions with or without a screen. With the latest firmware, the V4 is fully capable of operating as a solar- or battery-powered repeater using very little power.
- Best for: Permanent repeaters or solar-powered setups
- Also good for: Anyone needing long uptime or stable performance
- Tip: Choose the no-screen model to save even more power
RAKWireless WisBlock
WisBlock lets you customize your own hardware using swappable modules. It's reliable and efficient, and ideal for those who want to build a very specific type of node. With solar, batteries, and antenna options, it excels in outdoor and environmental setups.
- Best for: Advanced users building custom repeaters or sensor nodes
- Strengths: Expandable with extra modules
- Note: Slightly higher learning curve compared to Heltec boards
LilyGo T-Deck
The T-Deck combines everything into one device: screen, keyboard, speaker, battery support, and radio. It can operate independently without a phone. It's not designed as a repeater but makes an excellent portable mesh communicator.
- Best for: Personal use, demos, and traveling
- Strengths: All-in-one design, no phone pairing needed
- Not ideal for: Long-term unattended use or repeater duties
Building a Repeater
This is one of the most effective repeater builds used by the YQLMesh community. It’s solar-ready, outdoor-friendly, and efficient.
- Weatherproof solar box – $60
- Heltec V4 board – $42
- 2 rechargeable batteries – $3.88 each
- Outdoor antenna – $15
Total cost: About $124 CAD
With this setup, you can place a repeater on a building, pole, or mount it on a tree. It stays on 24/7 using solar power and helps relay messages through the network. You can find setup instructions on the Repeater Setup Guide page.
Why These Devices Matter
Each device added to the network helps make it stronger and more useful. Whether you’re running a node in your backyard or building repeaters for your town, your contributions help keep people connected when they need it most.
