The LILYGO T-Display-S3 AMOLED 1.43 is a compact ESP32-S3 development board with a circular 1.43-inch, 466 × 466 AMOLED touchscreen. It is a smaller-format alternative to LILYGO’s T-RGB display boards, not a resolution upgrade: the T-RGB’s documented 2.1-inch version has a 480 × 480 TFT LCD panel. Choose between them based on size, display technology, and project needs.
What is the LILYGO T-Display-S3 AMOLED 1.43?
It is a smart-display development board built around Espressif’s ESP32-S3R8, intended for embedded projects that need a small circular screen, touch input, wireless connectivity, and expansion options. LILYGO lists a dual-core LX7 processor running at 240 MHz, 16 MB of flash, and 8 MB of PSRAM. Wireless features include 2.4 GHz 802.11 b/g/n Wi-Fi and Bluetooth 5.0 LE. These are manufacturer specifications, not independent performance-test results. LILYGO’s product documentation and the official repository provide board details and software resources.
What screen and hardware does it include?
The round 1.43-inch panel uses an SH8601 AMOLED display controller and a QSPI interface, with 466 × 466 pixels. Capacitive touch is handled by an FT3168 controller. The listed board dimensions are 45 × 45 × 11 mm. LILYGO’s documentation does not establish brightness, battery runtime, water resistance, or durability, so those should not be assumed from the panel type or board size.
Recommended Free Tools
Other listed hardware includes a SY6970 power-management IC, a PCF8563 real-time clock, a TF card slot, USB Type-C with USB/OTG, STEMMA QT/QWIIC expansion, and a JST-GH battery connector. Check the documentation for the board revision and wiring before choosing a battery, replacement panel, or other accessory.

How does it compare with the T-RGB?
The T-Display-S3 AMOLED 1.43 and T-RGB are related circular-display development boards, but they differ in screen size and panel technology. LILYGO’s T-RGB documentation covers 2.1-inch half-circle and full-circle variants and a 2.8-inch full-circle variant; the exact variant matters because touch chips and glass covers differ. Hackster’s comparison reports 480 × 480 pixels for the 2.1-inch T-RGB panel. That is a larger panel with more pixels in each dimension than the AMOLED board’s 466 × 466, not a lower-resolution predecessor. Hackster’s comparison describes the T-Display-S3 as the more compact alternative.
| Feature | T-Display-S3 AMOLED 1.43 | T-RGB |
|---|---|---|
| Display | 1.43-inch circular SH8601 AMOLED, 466 × 466 pixels; LILYGO documentation | 2.1-inch or 2.8-inch circular TFT LCD variants; LILYGO documentation |
| 2.1-inch resolution | Not applicable; 1.43-inch panel is 466 × 466 pixels (LILYGO) | 480 × 480 pixels (Hackster.io; publication date not displayed on retrieved page) |
| Touch and variant details | FT3168 capacitive touch (LILYGO) | Varies by size and half-circle/full-circle version; identify the specific version in LILYGO’s listing |
| Board dimensions | 45 × 45 × 11 mm (LILYGO) | Not stated in the cited T-RGB page |
The available cited specifications do not establish a like-for-like comparison of processor, memory, or all interfaces across every T-RGB variant. The AMOLED model is the clearer fit when a compact 1.43-inch round screen is the priority; the T-RGB is the option to consider when its larger 2.1-inch or 2.8-inch format better suits the interface. Neither panel’s diagonal or pixel count alone establishes which will look better for a particular project.

How should you power it without a battery?
LILYGO warns that the SY6970 power-management IC’s output waveform can be unstable when the board is powered at 5 V without a battery connected. Its documentation gives two remedies: connect a battery, or use software to disable the battery channel. This is a manufacturer warning; follow the current board documentation and schematic when designing the power setup. See LILYGO’s power guidance.
Does it support Arduino and ESP-IDF?
Yes. LILYGO’s quick start documents Arduino IDE, PlatformIO, and ESP-IDF workflows, with examples for the display, touch, real-time clock, sleep, and SD-card functions. The repository lists dependencies including Arduino_GFX, Arduino_DriveBus, JPEGDEC, LVGL, and SensorLib. Use the instructions and example matching your framework and board revision; the repository’s named libraries do not guarantee compatibility with unrelated displays or accessories. The official repository is the starting point for setup and example code.

Check revision and screen compatibility before a build
LILYGO’s version history dates the V1.0 board to 2024-05-20. It records a 2024-11-25 revision adding an FPC cable and H0175Y003AM screen compatibility, followed by a 2025-01-13 revision adding DO0143FMST10 screen support. Confirm the exact board revision and installed panel before ordering a replacement screen or relying on a wiring detail. A matching diagonal measurement alone does not establish compatibility.
The board is a development platform, not a finished smartwatch. Although LILYGO lists wearable projects as a possible use, the cited product information does not establish consumer-watch features such as runtime, water resistance, or ruggedness. Price and stock also vary; check LILYGO’s current product and documentation pages for the latest availability.
