RouteSync is a compact, LoRa-based communication device designed for long-range messaging and emergency location sharing in environments where cellular networks are unavailable. Built around the RP2040 microcontroller and SX1262 LoRa transceiver, it integrates GPS positioning, USB-C LiPo charging, battery management, and an RF switching network into a compact four-layer PCB. Designed for outdoor adventures, remote travel, and emergency communication, RouteSync provides a reliable, low-power platform for transmitting location data over long distances while remaining portable and easy to carry.

RouteSync: common questions

What microcontroller does the RouteSync use?

The RouteSync is built around the RP2040, from the RP2040/RP2350 family.

How big is the RouteSync PCB?

The RouteSync measures 42 × 42 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RouteSync?

55 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the RouteSync design files?

From the Sai-Santosh09/RouteSync repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RouteSync design in my own project?

The repository has no license, so all rights stay with Sai-Santosh09. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RouteSync without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
