The ESP32-based obniz is a cloud-connected development board, which can be controlled with APIs, e.g. the REST or WebSocket API, over the obniz cloud. Obniz APIs can be used in JavaScript and easily run as a program on a webpage, due to the easy-to-use obniz.js library.

In fact, with obniz, it is easy to make any hardware project users can think of! They can just connect motors or sensors to an obniz development board and then program it over the Internet. No application or firmware flashing is required. Users can program their obniz board from their computer or smartphone. They only need HTML to integrate their obniz dev board and a webpage.

ObnizOS is the specific software that runs on the obniz development board, enabling its operation via APIs over the obniz cloud. ObnizOS can be installed and used on devices equipped with ESP32 and configured according to ESP32-WROOM-32.

ESP32-WROOM-32 is Espressif’s powerful Wi-Fi+BT/BLE module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks. ESP32-WROOM-32 contains the ESP32 SoC, flash memory, high-precision discrete components, and a PCB antenna which provides outstanding RF performance in space-constrained applications. ESP32-WROOM-32 has an optimized pinout. Peripheral IO pads are grouped and led out, thus facilitating application board designs with minimal external trace routing. This makes any resulting applications highly compact.

The obnizOS for ESP32 is now available for everyone to use. Programmers can install obnizOS to their ESP32 device and use it with JavaScript on their browser to control multiple devices, or use it with Python/Nodejs to connect hardware to a database or SNS easily. The newly-released obnizOS v2.0.1 contains important stability improvements.

Obniz is created by Cambrian Robotics Inc., a Japanese company headquartered in Tokyo.
