DIY GPS tracker for hiking trips
This device does not provide any map or direction info. It just shows GPS position, altitude, track length, track duration and current time. Track data is written to micro SD card as GPX file. Nothing too ingenious, but still quite handy if you like to gather the data on your hike. Thanks to large capacity 18650 rechargeable battery and low power circuitry (nRF51822 SoC) device can last well over 50 hours on one charge, which is enough for five day backpacking trip (thanks to track resume function it can be switched on and off with an “open” track), or 48h non stop ultra hike that i do once a year (that was primary purpose of this build).
