Build that perfect tracker for your personalized outdoors needs! Or a bluetooth sensor hub. Or a weather station. Or a wifi-controlled post-it note, a badge, datalogger, and so much more...

This board features a slew of sensors that can be used to make an awesome GPS tracker, weather monitor or biking computer. It is intended for makers who would like to play around with a reliable piece of hardware.

The design uses an ultra-low power, reflective memory LCD display, so you can see it clearly outdoors in bright light, and not kill the battery.

Features

  • 2.7" Sharp Memory LCD (ultra low-power, monochrome display)
  • GPS module with chip antenna
  • Temperature, pressure and humidity sensor (BME280)
  • Accelerometer and magnetometer (LSM303)
  • BLE for adding more sensors (speed and cadence, heart rate etc), WiFi for data transfer etc.
  • Micro SD card slot
  • 5-way switch, vibrator and an RGB led for user interaction
  • LiPo powered, with integrated charge management and regulation
  • Expandable I2C and UART ports to add your own extensions
  • Everything powered by an ESP32 with optional on-board USB programming interface

The hardware is open source, and software driver libraries are available for all the features. A very basic firmware is on its way to help get started. A few more details and links to source files for the entire project are available on Hackaday.

Happy hacking!
