Kinseal ASTG043W023 4.3″ COF TFT HMI Module (480×272)

by

Intro Summary
A compact 4.3″ industrial-grade touch‑screen HMI designed for embedded systems, offering ARM Cortex‑M4F control and RS232/485 comms in a slim package.

Product Overview
The Kanseal (Kinseal) ASTG043W023‑L480x272R‑0T0C is a 4.3″ COF TFT LCD HMI module with 480 × 272 resolution. It integrates an ARM Cortex‑M4F microcontroller, supports TTL 6‑pin XH2.54 interface, serial communication via CAN, UART (RS232/RS485), and USB. Its compact bezel‑free design is ideal for embedded control panels, industrial devices, or DIY automation. Compared to generic 4.3″ strips, it uniquely includes onboard MCU and communication interfaces—no need for external controller board.

How to Use

  1. Connect 5 V DC power to the 6‑pin TTL header (XH2.54).
  2. Interface via UART (RS232/RS485) or CAN to send commands and display graphics/text.
  3. Use provided IDE or firmware tools to prepare and upload UI screens.
  4. Mount into panel cut‑out (4.3″).
  5. Tips: Ensure COM ground reference; use level‑shifters if using 3.3 V logic. Observe industrial working temperature range (typically –20 °C to +70 °C).

User Review Summary
Lazada listings show solid interest: “4.3 inch, no housing, TTL signal cable” descriptions, with fast shipping and 97 % seller rating. Common pros: integrated MCU, compact, low price (~₫419 000, ~US$17), industrial ports. Cons: no enclosure; buyers need own housing; documentation may be limited in English.

Comparison with Competing Products
• Innolux AT043TN25‑V.2 4.3″ 480 × 272 TFT: Similar resolution and size but no onboard MCU or communication ports. Priced ~$28.
• Hantronix HDA430PT‑6 4.3″ 480 × 272 TFT: Pure display, no touch or MCU, $100—much pricier for raw panel.
• Displaytech DT043BTFT 4.3″ 480 × 272 TFT: Basic display module at ~$20, yet lacks touch and MCU functions.
ASTG is the only one with integrated touch, MCU, and serial ports—best value for DIY HMI solutions.
