# TinyGlobo
A pico balloon floats into the great big world, towing a [Raspberry Pi RP2040 Pico](https://www.raspberrypi.com/products/raspberry-pi-pico/) programmed with [TinyGo](https://tinygo.org).
This intrepid explorer reports data using LoRaWAN long-range radio over [The Things Network](https://www.thethingsnetwork.org/)
