M5 Stack recently launched a development board designed for IoT education. It helps teach developers how to carry out experiments and conduct research. Until now, there hasn’t been a similar product on the market offering all the learning possibilities of M5Stacks' Dev Board.
The board is a combination of all of their previous top-ranked products. It’s fully open-sourced and entirely compatible with other related products, making it the holy grail for IoT development by opening up endless possibilities.
