LILYGO T-RGB ESP32-S3: Single-board computer arrives with a circular touchscreen and battery support

LILYGO, a company known for making single-board computers (SBC) and touchscreens, has released the T-RGB ESP32-S3, a device designed to be used as a wearable. As the company's marketing images show, the device has a small circular display with a microcontroller on its reverse. Specifically, LILYGO has opted for a 2.1-inch TFT panel that operates at 480 x 480 pixels and supports touch input.

Powering the display is an Espressif ESP32-S3R8, an SoC that contains a dual-core Tensilica LX7 microcontroller that runs at 240 MHz. Additionally, the SoC has 8 MB of PSRAM at its disposal, along with 16 MB of SPI flash and a microSD card socket for storage expansion. Moreover, LILYGO has included a Grove I2C connector for connecting external actuators and sensors. Furthermore, the T-RGB ESP32-S3 has a 1.25 mm pitch connector a LiPo battery; alternatively, the device requires a 5V input via its USB Type-C port.

Currently, the T-RGB ESP32-S3 is out of stock on LILYGO's AliExpress store. However, the unit was recently available for US$32.28, a price that also included shipping and a battery cable. Similarly, LILYGO offers the T-RGB ESP32-S3 on Tindie for US$28.61 and US$35.61 through its website, although both sources are out of stock at the time of writing too. For reference, the manufacturer has shared a schematic and various other documents on GitHub, such as an Autodesk template for a 3D-printed enclosure.
