Pulga Core V2.0

The Caninos Loucos Pulga board is a powerful microcontroller with a large number of sensors, highly secure, and ideal for IoT applications. Completely designed in Brazil.

The low power board is approximately the size of a quarter dollar coin (24,26mm) and supports Bluetooth 5.0, allowing for wireless connection between multiple Pulgas.

Aspects such as modularity, via an autonomous core board and an optional base board, and energy harvesting capability, enables great exibility for hardware interfaces prototyping.

The base board allows for adding functionality for custom applications. For example, by adding long distance wireless protocols and new sensors, you can meet the demands of dierent projects.

Finally, the harvesting allows for capturing energy from dierent environmental sources, ensuring energetic autonomy to the board.
