ESP32 Ninja is a ultra-small (29 x 37 mm), high-quality, 4 layer ESP32 IoT development board. It hosts all the hardware you may need in an tiny form factor in order to be used in custom IoT applications, primarily as a temperature and humidity node.

The project started as a challenge to build the smallest development board out there that supports USB UART and USB OTG interfaces, and is also packed with solutions for the most common issues a hobbyist or a researcher might deal with when tinkering and prototyping a new project, especially around IoT.

ESP32 Ninja can be a completely independent IoT node, giving feedback via the RGB LED or add-on OLED screen, while being able to accept input via two onboard buttons. It is designed with power and portability in mind with an ultra-low power mode and lithium polymer battery support, with a BMS (Battery Managment System) and a SoC (State of Charge) IC.
