LILYGO T-QT Pro 0.85-inch WiFi IoT display adds support for battery charging

LILYGO T-QT Pro is an ESP32-S3 WiFi and BLE IoT board with a 0.85-inch color display, 4MB flash, 2MB PSRAM, a USB-C port, a few GPIOs, and support for LiPo battery with charging. It is an upgrade to the ESP32-S3-based LILYGO T-QT V1.1 board that also supports LiPo battery power but lacks a charging circuit, so you had to remove the battery and charge it manually each time. The T-QT Pro adds a charging circuit and switches from an ESP32-S3 with an 8MB flash design to one using ESP32-S3FN4R2 with 4MB flash and 2MB PSRAM. LilyGO T-QT Pro specifications: Wireless MCU – Espressif Systems ESP32-S3FN4R2 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 4MB flash, 2MB PSRAM, wireless connectivity Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, […]

LILYGO T-RSC3 ESP32-C3 board features isolated RS232 & RS485 interfaces, 5 to 24V DC input

LILYGO T-RSC3 is a relatively compact ESP32-C3 board with WiFi 4 and Bluetooth LE 5.0 connectivity, support for RS232 and RS485 communication protocols through a DB9 connector and a terminal connector respectively, and a wide 5V to 24V DC power input. LILYGO had already made an ESP32 board with CAN Bus and RS485 interfaces called the T-CAN485, but without any isolation. The new T-RSC3 offers both RS232 and RS485 interfaces, but no CAN Bus, protected by isolated transceiver modules that should make it safer to use in industrial environments. LILYGO T-RSC3 board specifications: Wireless module – Espressif Systems ESP32-C3-MINI-1U module with ESP32-C3 RISC-V microcontroller @ 160 MHz with 400 KB SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh, 4MB flash, and a u.FL antenna connector Industrial control interfaces RS232 via DB9 connector, RSM232MT5V isolated transceiver with 3000V isolation, 4.75~5.25V input, 5V/50mA output, baud rate from 1200 to 256,000 […]

LILYGO T-RGB round color touch display is powered by ESP32-S3R8 wireless microcontroller

LILYGO T-RGB is a wireless 2.1-inch round color touchscreen display based on ESP32-S3R8 dual-core microcontroller with WiFi 4 and Bluetooth 5.0 connectivity, 8MB PSRAM, and 16MB flash storage. The device also includes a microSD card socket for data storage and a Grove I2C connector for expansion and supports LiPo battery power. The company also says it can be charged through USB, so the board must include a battery charging circuit contrary to some other boards from LILYGO. LILYGO T-RGB specifications: SoC – Espressif ESP32-S3R8 dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration, 8MB PSRAM, WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.1-inch round 18-bit RGB color IPS TFT display with 480×480 resolution (ST7701S SPI controller), touchscreen panel USB – USB Type-C port for power and programming Expansion – Grove I2C connector Misc […]

ESP32 board supports 2.4Ghz LoRa with SX1280 RF transceiver

We’ve seen plenty of ESP32 LoRa boards with the traditional 433 MHz, 868 MHz, or 915MHz frequencies, but I think LilyGO LoRa V1.8 (aka T3 V1.8) is the first ESP32 board that integrates a Semtech SX1280 transceiver for the 2.4GHz LoRa standard used for global coverage, notably maritime applications, and ranging. The ESP32 & SX1280 board also offers 26 pins for expansion, a microSD card for data storage, a 2-pin connector for batteries, a 0.96-inch OLED for information display, and comes with a 3D antenna and u.FL connector for WiFi and Bluetooth, and an SMA antenna for LoRa connectivity. LilyGO LoRa/T3 V1.8 specifications: SoC – Espressif ESP32 dual-core Xtensa LX6 processor with 2.4 GHz WiFi 4 and Bluetooth 4.2 Storage – 4MB SPI flash, microSD card slot Display – 0.96-inch OLED display with 128×64 resolution (SSD1306 I2C driver) Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps + Bluetooth 4.2 […]

$52 7.5-inch E-paper display connects to ESP32 boards

LILYGO 7-5 inch E-paper Display with T5 ESP32 board

So far LILYGO’s ESP32 boards with an E-Paper display such as the TTGO T5 or Mini E-Paper Core featured smaller displays from 1.02-inch to 2.9-inch. But the company is now offering a larger 7.5-inch display that works with most of its T5 boards excluding the one used with a 4.7-inch display. The black and white e-paper display offers a resolution of 800 x 480 pixels, is Arduino programmable and backward compatible with earlier T5 E-paper solution, and should be one of the most cost-effective to way to make a wireless E-paper display. LilyGO 7.5-inch E-paper display specifications: Panel SKU – DKE DEPG0750_U790F3 (See PDF datasheet. note non-secure link so your browser may complain) Size – 7.5-inch diagonal Resolution – 800 x 480 pixels (124 DPI) Active area – 163.2 x 97.92mm Pixel pitch – 0.204 x 0.204 mm Host interface – SPI Dimensions – 170.2 x 111.2 x 1.2 mm […]

T-Display-S3 board offers ESP32-S3 WiSoC, 1.9-inch color LCD, and LiPo battery support

LilyGO T-Display-S3 is an ESP32-S3 WiFi and Bluetooth LE IoT development board with a 1.9-inch color LCD and support for LiPo batteries that follows the company’s T-QT ESP32-S3 board with a tiny 0.85-inch display introduced earlier this month. The new board offers the same layout as the previous T-Display RP2040 or ES32 boards, but the 1.14-inch display has been replaced with a larger 1.9-inch display that covers most of the board, and thanks to the ESP32-S3 microcontroller, gains proper Bluetooth 5.0 support, as well as vector instructions for AI acceleration. T-Display-S3 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM, wireless connectivity Storage – 16MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.
