ESP32-S2-HMI-DevKit-1 for Human Interaction

ESP32-S2-HMI-DevKit-1

The ESP32-S2 single-core Wi-Fi processor from Espressif System has an RGB LCD interface that makes it suitable for multimedia applications. The ESP32-S2-Kaluga-1 also a Multimedia Development Board with a touchscreen display and a camera was released two years ago.

Espressif, the fabless semiconductor company, has now launched a new HMI (human-machine interface) development kit. It is based on the ESP32-S2 for smart home automation controllers, smart speakers with displays, smart alarm clocks, and other devices. 

Human-machine interface (HMI) is a term that describes a user interface that allows humans to communicate with machines. A desktop with a touch panel, a push button, a mobile device, or a computer with a keypad is all examples of HMI physical aspects. The ESP32-S2-HMI-DevKit-1 is a touch-screen device with a 4.3-inch color LCD display.

The ability to closely track production and respond to evolving production demands increases productivity and reduces downtime. Hence is the most useful feature of HMI technology from an industrial standpoint. A well-designed HMI solution not only improves the operator’s efficiency but also offers a line of sight into the device for controlling or maintaining the computer.

ESP32-S2-HMI-DevKit-1 Specifications

It has a wireless module, which features the ESP32-S2-WROVER module with ESP32-S2 Xtensa single-core 32-bit LX7 microprocessor clocked up to 240 MHz frequency. Additionally, with a 128 KB ROM, 320 KB SRAM, it has Wi-Fi 4connectivity. Furthermore, the development kit has got 4 MB flash storage and a 2 MB PSRAM.

The ESP32-S2-HMI-DevKit-1 features a 16-bit display interface, a 20 MHz processor, and 8080 parallel communication. It has an I2C capacitive touch panel in addition to the 4.3-inch touchscreen with 800×480 resolution. Additionally, it comes with a built-in microphone, an audio amplifier, and a speaker connector.

The development kit also gets a 1950 mAh rechargeable lithium battery with 5V and 3.3V power headers. Also, peripheral interfaces such as Prog & UART, SPI, TWAI, I2C, and a Micro-SD card slot are included on the development board. It has a variety of sensors and features, including audio replay and recording. The sensors in ESP32-S2-HMI-DevKit-1 includes the three-axis accelerometer, three-axis gyroscope, ambient light sensor, temperature and humidity sensors. Furthermore, its low-power output extends the device’s standby time significantly. As a result, the ESP32-S2-HMI-DevKit-1 is extremely affordable.
