LILYGO T-Energy-S3 ESP32-S3 board offers 18650 battery holder, two 20-pin GPIO headers

ESP32-S3 board with 18650 battery holder

LILYGO T-Energy-S3 is an ESP32-S3 WiFi and Bluetooth IoT board with an 18650 battery holder, a USB-C port for charging and programming, and plenty of I/Os thanks to two 20-pin GPIO headers and a Qwiic connector. We’ve already covered a large number of ESP32-S3 boards and products, including some designs for battery operation such as the Tokay Lite AI camera board, LILYGO’s T7-S3 board, and Smart Bee Designs’ Bee S3 board among others. But that usually means providing a 2-pin connector and charging circuitry to connect a LiPo battery, but the T-Energy-S3 ESP32-S3 board works directly with an off-the-shelf 18650 rechargeable Lithium battery. T-Energy-S3 specifications: Wireless Module – ESP32-S3-WROOM-1-N16R8 Espressif Systems ESP32-S3R8 – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM Storage – 16 MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth PCB antenna USB – 1x USB […]

ESP32-S3 rotary encoder features 1.2-inch AMOLED touchscreen display and Qwiic connectors

LILYGO T-Encoder-Pro is a rotary encoder based on Espressif Systems ESP32-S3 WiFi and Bluetooth SoC, equipped with a 1.2-inch AMOLED with touchscreen support, and two Qwiic connectors for expansion. LILIGO T-Encoder was introduced in 2022 with ESP32 WiFi and Bluetooth SoC and a few GPIOs that enabled it to be fitted on a 2-key keypad shield. The LILYGO T-Encoder Pro has a completely different design with a more advanced ESP32-S3 SoC, an integrated touchscreen display, and GPIOs are now exposed through Qwiic connectors instead of headers. LILYGO T-Encoder-Pro specifications: Wireless SoC – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 8MB PSRAM Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – 16 MB flash (W25Q128) Display – 1.2-inch rounded AMOLED with ∅390mm resolution via SH8601A-W14-T06 QSPI controllers; CHSC5816 I2C touch and rotary encoder chip […]

LILYGO T-Camera-Plus-S3 – An ESP32-S3 powered dev board with night vision camera and touchscreen display

LILYGO T Camera Plus S3 ESP32 S3 Camera Development

The LILYGO T-Camera-Plus-S3 is an ESP32-S3 development board designed for building smart home devices, monitoring systems, and other connected projects. The board features a 1.3-inch TFT LCD and the option to choose from OV2640 or OV5640 camera modules. The T-Camera-Plus-S3 can be considered an upgrade from the T-Camera S3, which was introduced in 2022. The upgraded features include a 1.3″ SPI TFT LCD (240×240), a microphone with MAX98357A codec and external speaker support, support for a micro SD card, a battery connector, and many other features. Previously we have written many different types of ESP32-S3-based boards like the Waveshare ESP32-S3-Matrix, ESP32-S3-Tiny board, and Unexpected Maker NANOS3 feel free to check those out if you are looking for unique ESP32 boards. LILYGO T-Camera-Plus-S3 specification ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz (Note: this SKU is not listed in the official ESP32-S3 datasheet) with 2.4 GHz 802.11n […]

LILYGO T-Panel – A 4-inch HMI display and WiFi, BLE, and 802.15.4 gateway based on ESP32-S3 and ESP32-H2

T-Panel 4-inch ESP32-S3 and ESP32-H2 gateway

LILYGO T-Panel is both a 4-inch HMI display and IoT gateway based on ESP32-S3 WiFi 4 and Bluetooth LE 5 microcontroller and an ESP32-H2 module with Bluetooth LE 5 and an 802.15.4 radio for Zigbee, Thread, and Matter connectivity. Last year, Espressif introduced the ESP-Thread Board Router/Zigbee gateway board with ESP32-S3 and ESP32-H2 to show how both chips could be combined to create IoT gateways. But I don’t think I had seen a company design a product based on both ESP32-S3 and ESP32-H2 until I saw the T-Panel which also includes an RS485 interface and Qwiic expansion connectors for good measure. T-Panel specifications: Wireless chips/modules Wireless SoC – ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Wireless module – ESP32-H2-MINI-1 module MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 […]

LILYGO T4-S3 board combines 2.41-inch AMOLED touchscreen display with ESP32-S3R8 microcontroller

LILYGO T4-S3 is yet another ESP32-S3 board with an integrated display, but the main difference here is the 2.41-inch AMOLED touchscreen display with brighter colors than typical TFT displays. It’s actually not the first ESP32-S3 board with an AMOLED display from LILYGO as we previously covered the T-Track and T-Display-S3 AMOLED boards from the company, but the new T4-S3 has a larger 2.41-inch display with touchscreen function and an aspect ratio that may make it more suitable for a wider range of HMI applications. LILYGO T4-S3 specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.41-inch RGB AMOLED touchscreen display with 600×450 resolution (QSPI controller) with 800cd/m2 brightness, 36.2 x 48.96mm active […]

T-Keyboard-S3 4-key USB mechanical keyboard features keycaps with 0.85-inch color display

LILYGO T-Keyboard-S3 is an ESP32-S3 powered USB mechanical keyboard with four keys each equipped with a keycap featuring a 0.85-inch 128×128 color display to show different icons or characters. We have already covered several programmable small mechanical keyboards/keypads or macropads, so the first time I saw the T-Keyboard-S3 I did not think much of it until I read the $65 price tag on Aliexpress which I found excessive for this type of device. That’s only until I realized that each resin keycap has its own color display that the price made sense, and it makes quite a versatile macropad as you could easily program multiple layouts depending on the use case. T-Keyboard-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3R8 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh […]

LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller

LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]
