Vision Master T190

1.90-inch TFT-LCD Display with ESP32 and LoRa Module (optional)

Description

Vision Master T190 (HT-VMT190) is a development kit with ESP32-S3 and LoRa Module (optional). The onboard 1.9-inch TFT-LCD display contains 170 (RGB)X320 dots and can display up to 262k colors.

Working with the sample programs and development tools we provide, users can operate the display via Bluetooth, Wi-Fi and LoRa. It also supports daily entry-level programming, and runs open source projects like Meshtastic.

Compared to WiFi LoRa 32 (V3) , Vision Master T190 has made the following upgrades:

High light

Highly extensible

Vision Master T190 has a rich set of pins and hardware resources, which will allow you to expand widely. The SH1.0-4P interface can be directly connected to the QuickLink series sensors.

Plastic support plate

A transparent plastic support platform is installed between the PCB and the display frequency, which can protect the electronic components on the board and enhance the heat dissipation function of the board.

Type-C USB interface and battery interface

Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.
Battery interface
Low power consumption, 18uA in deep sleep.
