Developers often ask us the difference between TTGO and LILYGO. When dealing with various T-Beam and T-Echo products, some pictures will show the former, while others show the latter. Many of the product titles include both words. What do they mean?
The company/manufacturer name is LILYGO, however it used to be called TTGO. So this is why there is still some occasional photos that reference TTGO, and why both company names are still used in product titles.
