Olimex ESP32 Evaluation Board
Introduction
The ESP32 is a chip manufactured by Espressif Systems Co., Ltd that includes Bluetooth and WiFi capabilities and used in mobile devices. In the demonstration, the ESP32 is used in the form of an evaluation board manufactured by Olimex. The board deployed in the demonstration is Revision I of the product.
Licensing Information
The Olimex ESP32-EVB is certified by the Open Source Hardware Association (Certification UID BG000011).
Application: software and function
The ESP32-EVB is used to demonstrate a sensor device and the use of the OMA Lightweight Machine to Machine (LwM2M) protocol. The sensor device is implemented on a ‘breadboard’ so that the components of the device can be seen clearly. A functionally similar circuit will be implemented on boards for the feather and conventional Arduino form factors, the schema and bill of materials for the circuit and boards can be found in the repository at https://codeberg.org/sudo-iot/sensor-board-prototype.
The software reads data from the sensors in the circuit board and uses Eclipse Wakaama to transmit data over a wired Ethernet connection to an Eclipse Leshan server that runs on the Beaglebone Black board in the demonstration.
