Features:

1. Adopting ESP32-S3R8 main control chip, supporting WiFi and Bluetooth.

2. The LoRa module is optional and compatible with Mashstick.

3. Low power consumption, deep sleep 18uA.

4. Powerful display function, onboard 1.9-inch TFT-LCD display screen, including 170 (RGB) X320 dots, can display up to 262K colors.

5. High contrast, high reflectivity, and ultra wide viewing angle.

6. The SH1.25 sensor interface is perfectly compatible with the QuickLink series sensors.

7. Compatible with open-source software and hardware platforms, we provide an example development framework and library.

8. Supports USB/lithium battery power supply, with the option to choose between 3.3-4.2V lithium battery power supply or USB charging. The advantage of using USB and lithium battery power together is that it can enhance power supply reliability, improve battery life, adapt to various scenarios, optimize charging management, and improve device compatibility.

9. The combination of TFT-1.9-inch screen display and LORA wireless technology ensures high-quality screen display effects, stable long-distance data transmission, and meets the low-power operation requirements of devices.
