LILYGO T-Circle-S3 – An ESP32-S3 devkit with 0.75-inch circular touch display, microphone and speaker

The LILYGO T-Circle-S3 is a circular touch display development board built around the ESP32-S3 MCU and designed for smart gadgets, IoT devices, and wearable applications. The board integrates Wi-Fi 4, Bluetooth 5.0, a MEMS microphone, a 3W Class-D audio amplifier with speaker support, an RGB LED, six rear GPIO pins, a Qwiic interface, and USB-C for charging. The board is very similar to the Waveshare RP2350-LCD-1.28, with its round display design, but it does not support wireless connectivity and audio. It also resembles SB Components’ Dual Roundy (ESP32-S3),  but compared to that, the T-Circle-S3 is smaller and features a touch display, a microphone, a speaker amplifier, and an RGB LED. LILYGO T-Circle-S3 specifications: Wireless SoC – ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instruction Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM Wireless – 2.4 GHz WiFi 4 and Bluetooth LE Storage […]

ESP32-S3 LCD Driver Board supports both circular and square displays

Waveshare ESP32-S3 LCD Driver Board is a compact development board designed to simplify the GUI development process. The company mentions that the board supports 2.1-inch, 2.8-inch, and 4-inch displays and with an additional SPI and I2C header it can support a wide range of LCD panels. Additionally, the board features an onboard lithium battery charger and 15 usable GPIO pins for added flexibility. These features make this device suitable for applications like smart home devices, industrial control panels, and interactive kiosks. It seems like the board supports the 4-inch LF40 square touchscreen display that we wrote about just yesterday. other than that it also supports 2.1-inch and 2.8-inch circular displays. Seeking off circular displays, we have previously written about some ESP32-powered development boards with circular displays like the Waveshare 1.69-inch IPS touch LCD, the Waveshare RP2040-LCD-0.99-B, the Waveshare ESP32-S3-LCD-1.28 and many other types of displays. Feel free to check those […]

Compact development board features a single ESP32-P4 + ESP32-C5 dual-band Wi-Fi 6 module, MIPI display and camera interfaces

Just a few months back, Wireless-Tag released the WT99P4C5-S1, which combines the ESP32-P4 with an ESP32-C5 dual-band WiFi 6 module, instead of the more commonly used ESP32-C6 wireless module found on most ESP32-P4 development boards we’ve covered. The company has now released the WTDKP4C5-S1, a more compact development board built around the WT01P4C5-S1 ESP32-P4 and ESP32-C5 core module. The board supports MIPI-CSI and MIPI-DSI through the ESP32-P4, while the SDIO-connected ESP32-C5 provides dual-band Wi-Fi 6 (2.4/5 GHz) connectivity along with BLE 5, Zigbee, Thread, and Matter. Other features include a USB 2.0 Type-C OTG port, two UART debug interfaces, two 40-pin GPIO breakouts from both chips, and various power options via USB-C, a 12V DC input, or headers. The board is suitable for LVGL-based HMIs, data acquisition, industrial control, and Edge AI applications such as IPCs and smart displays.
