LILYGO T-QT V1.1 – A cute little board with ESP32-S3 and a 0.85-inch color display

LILYGO must be churning out at least one new “ESP32” board every month, but I don’t think they’ve ever made one with ESP32-S3. LILYGO T-QT V1.1 board changes that and combines the dual-core WiFi 4 and Bluetooth LE 5.0 AI microcontroller with a 0.85-inch color display. The board also happens to be rather small and cute with a 33 x 18 mm form factor, offers some I/O via headers and a 4-pin connector, and can be powered via its USB Type-C port or a battery, but lacks a charging circuit. LILYGO T-QT V1.1 specifications: Wireless MCU – Espressif Systems ESP32-S3 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, wireless connectivity Storage – 8MB 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.

ESP32 board with 150Mbps 4G LTE modem also supports RS485, CAN Bus, and relay expansion

LILYGO has designed another ESP32 board with a 4G LTE modem with the LILYGO T-A7608E-H & T-A7608SA-H variants equipped with respectively SIMCom A7608SA-H for South America, New Zealand, and Australia, and SIMCom A7608E-H for the EMEA, South Korean, and Thai markets, both delivering up to 150 Mbps download and 50 Mbps upload speeds. The board also supports GPS, includes a 18650 battery holder, and features I/O expansion headers that support an add-on board with RS485 and CAN bus interfaces, in a way similar to the company’s earlier TTGO T-CAN485 board with ESP32, but no cellular connectivity.

How to use a ToF laser ranging sensor with Arduino and Wisblock

Laser ranging has many applications in production and life, such as ranging, positioning, obstacle avoidance, and so on. Time-of-Flight (ToF) ranging, as a type of laser ranging technology, is often used for real-time object detection in robots, autonomous vehicles, and traffic management because of its accuracy, fast response, and low power consumption. The face detection function of mobile phones also uses this technology. This article will introduce the WisBlock RAK12014 ToF laser ranging sensor module, and use the WisBlock development board to demonstrate how the module works. What is a ToF laser ranging sensor module? A ToF laser ranging sensor module uses laser pulses to measure the distance between itself and a target object. The WisBlock RAK12014 ToF laser ranging sensor module is based on STMicro VL53L0X, the smallest ToF ranging sensor in the world. The WisBlock RAK12014 provides accurate distance measurement and can measure distances up to 2 meters. […]
