Waveshare shows compact portable touchscreen display with battery, also for smart home use

The manufacturer Waveshare is likely quite familiar to many makers. With the ESP32-S3-Touch-LCD-1.85B, the company offers - depending on the perspective - either a display with a development board or a development board with an integrated display. It also comes with a case.

Let's take a moment to assess the system overall: Purchasing the ESP32-S3-Touch-LCD-1.85B only makes sense for users who aren't afraid of programming, regardless of their specific project. AI tools, the Arduino IDE, and ESP-IDF can all be used for development. It's certainly conceivable to use it as a small smart home display as well.

Measuring 61.6 millimeters in diameter and 14.6 millimeters thick, the system features a 1.85-inch AMOLED display with a resolution of 360 × 360 pixels. According to the manufacturer, the display offers a brightness of 450 cd/m² and includes touchscreen capability. However, interaction with the system is also possible via an array consisting of two individual microphones. It includes both an accelerometer and a gyroscope. A programmable button is built in, and audio output is supported. Wireless data transmission is possible via Wi-Fi and Bluetooth.

Programming and power supply are both possible via USB Type-C, though battery operation is also supported. The ESP32-S3-Touch-LCD-1.85B is listed on Waveshare for a price of at least $26 but is currently unavailable. Alternatives can be purchased on Amazon, for example, such as the Elecrow 480×480 2.1-inch development board.
