Learn more about Espressif’s recently launched ESP32-S2-HMI-DevKit-1, which is specifically designed for human-machine interaction.

Espressif has recently launched ESP32-S2-HMI-DevKit-1, which has been specifically designed for human-machine interfaces in smart-home automation controllers, smart speakers with display, smart alarm clocks, etc. It comes with a 4.3-inch, color LCD and a touch panel.

ESP32-S2-HMI-DevKit-1 is powered by the ESP32-S2-WROVER module, which supports a 4.3-inch LCD screen. The development board has a 1950 mAh rechargeable lithium battery and peripheral interfaces such as Prog & UART, SPI, TWAI, I2C, and an SD card. It supports various  sensors, and such functions  as audio playback and recording. In addition, its low-power performance increases the standby time of the device considerably. As such, ESP32-S2-HMI-DevKit-1 is truly cost-effective. Additionally, this development kit supports rapid secondary development, since developers can take advantage of the kit’s various onboard resources and expansion interfaces, in order to develop various different functions.
