The ability to work with a 3.7V LiPo battery is also a plus.īut there are two points that could be improved Sensor integration is made easy thanks to the Mabee/Grove connectors that accept many modules available on the market. The MaTouch_ESP32-S3 4-inch display board works great and the speaker set is loud and clear. The MaTouch_ESP32-S3 4-inch Display Demo Kit with its display board and sensors is very easy to use notably thanks to the provided Arduino samples. We can then “transfer” the new user interface to the Matouch_ESP32-S3 4-inch display board and it looks much better than the text-based-only interface we tested above. We can modify the user interface of the IAQ monitor with LVGL using SquareLine Studio.

The video is also in Thai language, but it shows the LVGL widgets, tab switching, charts drawing, etc… There’s a lag, which reminds me of the experience I had with a Windows PDA I owned many years ago, but this should be expected on low-end hardware and should still be fine for many HMI applications. After installing the LVGL library, and we used the sample for the ESP32-S3 4-inch display board as shown in the video below. The 4-inch screen is large enough to be used in a variety of applications and is suitable for graphical user interfaces built with the popular LVGL open-source graphics library which allows users to create nice-looking user interfaces. Using LVGL graphics library with the MaTouch_ESP32-S3 display kit Arnon – the reviewer – shot the video in Thai, but it shows a candle on the left and a glass of water on the right and we can see the heatmap and temperature measurements on the display.
The video below shows the test results of readings from the Mabee MLX90640 module sensor.

The code will read the values from the MLX90640 thermal camera, display them as a heatmap on the screen, and show the maximum temperature measured in the image frame. Serial.print(" size: ") Serial.println(ts.points.size) Serial.print(" y: ") Serial.print(ts.points.y) Serial.print(" x: ") Serial.print(ts.points.x) Serial.print("Touch ") Serial.print(i + 1) Serial.print(": ") TAMC_GT911 ts = TAMC_GT911(I2C_SDA_PIN, I2C_SCL_PIN, TOUCH_INT, TOUCH_RST, max(TOUCH_MAP_X1, TOUCH_MAP_X2), max(TOUCH_MAP_Y1, TOUCH_MAP_Y2)) We’ll use ArduinoGFX and configure the I/O pins as follows: The display relies on parallel RGB565 and SPI interfaces, and it’s supported by the ArduinoGFX library or the LovyanGFX library. The ESP32-S3 4-inch display board can be programmed with either Arduino or PlatformIO, and we’ll use the demo code provided by Makerfabs on GitHub for this review. Programming the Matouch_ESP32-S3 demo kit with Arduino/PlatformIO We can also peel the film on the adhesive paper on the speaker to attach it to the back of the frame. We can mount the ESP32-S3 4-inch Display board to the 3D-printed frame with the provided spacers, bolts, and nuts. The kit also comes with a speaker attached to the main board, a 3D printed frame/holder, a microSD card, a USB Type-C cable, and a screw set. The “Mabee TVOC and eCO2 SGP30 & Temperature and Humidity SHT31” module, which as its name implies, combines an SGP30 TVOC and eCO2 sensor (I2C address: 0x58) and an SHT31 temperature and humidity sensor (I2C address: 0x44), and operates at 3.3V. Temperature measurement range – -40☌~300☌, ☑.5☌ resolution.IR Thermal Sensor Array 32×24 (MLX90640).The Mabee MLX90640 thermal camera sensor with the following specifications: Expansion – 2x Mabee interfaces: 1x I2C 1xGPIO.USB – Dual USB Type-C (one for USB-to-UART and one for native USB) USB to UART Chip: CP2104.5 Points Touch, Capacitive via GT911 touch panel driver.4.0-inch IPS display with 480×480 resolution, 50+ FPS RGB 5/6/5+ SPI interface using ST7701S controller.Controller – ESP32-S3-WROOM-1, PCB Antenna, 16MB Flash, 8MB PSRAM, ESP32-S3-WROOM-1-N16R8.
