LoRa communication with Satellite on a Budget

By | Electronics Laboratory, Radio Communicaion

Radio and Wireless communication has always amazed me since I was a kid. We can not imagine our life without relying on wireless communication in current date. Be it WiFi or Cellular connectivity, almost everything rely a lot on Wireless Communication. The Wireless Technology has developed a lot since its inception. One of the interesting technology is LoRa, which stands for Long Range.

Although communication with satellite is nothing new. My friend Martin from U.K. (Call Sign G0PYB) is doing it since ages. The LoRa communication using satellite is something new and interesting. The LoRa communication requires much less power and have long range compared to other wireless protocols. With launch of many Cubesats (basically small satellites) in LEO (Low Earth Orbit), for educational and scientific purpose, anyone with access to basic hardware can access to LoRa communication using Satellite.

Interestingly, at the time of writing, there is one project named TinyGS, which will help you to get started with it. As per their website:

"Initially TinyGS was born under the name ESP32 Fossa Groundstation, it was developed as a "weekend" project for the FossaSAT-1 LoRa satellite. We are passionate about space and created this project to be able to track and use the satellites and to learn and experiment about radio. Currently the network is open to any LoRa satellite and we also support other flying objects that have a compatible radio modulation with our hardware such as FSK, GFSK, MSK, GMSK, LoRa and OOK. And the project was renamed to TinyGS."

There is very helpful community on Telegram ( where people are very helpful to get started with the TinyGS Project. The recommended hardware are listed at wiki page of TinyGS i.e. at

This post is all about getting started with TinyGS project with very basic hardware in a budget friendly manner. Please note that connecting to OLED display is optional. To get started you would need the following Bill of Material (BOM):
