Waypoint
A handheld GNSS navigation device designed to help you to get to a destination without relying on mobile reception.
Ever wanted to get somewhere from anywhere? Waypoint uses GNSS to guide you towards your destination by showing the direction, distance, and elevation difference. It does not provide turn-by-turn routes, but instead gives you all the other needed informations to navigate independently.
It is powered by a 3200mAh LiPo battery, an efficient MCU, and separated power domains to achieve long battery life.
How to use it
- Save your current location
- Travel somewhere else
- Select your saved location
- Navigate back using the provided direction and distance information
Why
I built Waypoint for Fallout 2026 because I wanted to create a project involving RF and battery management.
With this project I learned a lot about embedded Rust with the embassy framework.
Specs
- 20 sk6812s LEDs to indicate the needed bearing
- 240x240 GC9A01 oled screen
- ATGM336H GNSS module
- Esp32-c6
- usb-c charging
- imu + magnetometer
- haptics (DRV2605L + LRE)

Magazine page
Build it yourself
PCB
Order all components from the bom from your prefered site. It already includes links to lcsc and aliexpress. Also order the pcb from the releases with the gerbers. I would recommend getting a stencil as the design includes some tricky footprints.
Soldering
Start by soldering all smd components, then do all the tht ones.
Case
Print all .3mf files in here. Printing the top and bottom in different colors gives it a nice touch! See the example images for inspiration.
Flashing
Get the firmware file from releases. Flash it with ur prefered esp flashing tool over the usb port or the exposed uart. You can use espflash or espressifs web tool
Assembly
- Stick the battery in the bottom of the case and connected it to the pcb (please make sure that the batteries polarity matches the pcbs)
- Press the pcb into the bottom. Align it with the posts
- The top requires some force to press on, as it uses snap fits. If there is too much friction sand the lip a bit down.
- Done

Questions
How big is the Waypoint PCB?
It measures 140 × 80 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Waypoint use?
187 parts, built around the ATGM336H-5NR32, ESP32-C6-WROOM-1-N8, BQ24073RGTR and BX-PH2.0-2PWZ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Waypoint KiCad files?
From the M-Mrk/waypoint repository on GitHub, at the commit this page was made from: the board is pcb/waypoint.kicad_pcb and its schematic pcb/leds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Waypoint design in my own project?
Its repository states no licence, so its author keeps all rights: ask M-Mrk before reusing the design.
