🛆 Overview
The 'Mini RAK-Tracker' is based on the RAK3172 microcontroller from RAKwireless. This board computer encapsulates an STM32WLE5CC and all the components needed to run it.
The board is equipped with LoRa communication integrated into the RAK3172, a geolocation chip and several environmental sensors.

Main components
🛆 Conception
The board is connected to three mouse bits. This allows information to be displayed for a better understanding of the board. It's always handy to be able to pull out this piece of board instead of a documentation to find the component. Separating the board from the panel is easy.
Front Side
On the front of the board are the components that bring the board to life: the sensors. To the right are the three environmental sensors and the power switch. To the right are the flash, indicator LEDs and a reset button with a jumper for bootoloading. In the centre of the board is the essential element, the GNSS chip.
Back Side
The back of the board contains the microcontroller and a user LED. At the bottom is the chip that communicates with the on-board computer and the power assembly: the voltage regulator, the battery charger and its slot.
