Description
Arduino Display 0.96 inch TFT Modules 80×160 SPI TFT Display ST7735S Controller
The HTM-H010W21-SPI-V0 is a 0.96-inch, 80×RGB×160 high-brightness, wide-viewing-angle TFT LCD display module. It integrates the ST7735S dedicated micro color LCD driver and communicates with the host via a standard 4-wire, 8-bit SPI serial data interface. With its ultra-compact PCB size (24.00mm × 30.00mm) and onboard mounting holes, making it an ideal Arduino Display SPI solution for space-constrained projects.
Key Highlights
- Ultra-Wide Viewing Angle – Full viewing angle design: U80/D80/L80/R80 (typical) ensures no color shift or distortion from any direction.
- High Brightness & Constant-Current Backlight – Typical brightness of 400 cd/m², supports constant-current drive, remains clearly visible in strong light or outdoor shaded environments.
- Industrial-Grade Wide Temperature Range – Operating temperature: -20℃ to +70℃; storage temperature: -30℃ to +80℃, suitable for harsh industrial or outdoor applications.
- Excellent Color Performance – NTSC 45% color gamut coverage, delivering 65K vivid colors and smooth animations in a tiny 0.96-inch space.
- Low Power & Anti-Sticking Mechanism – Built-in optimized driving circuit supports partial display, sleep mode, and long-life specifications.
Pinout & Interface Description
To achieve high-speed serial communication with the host MCU, the module condenses all control and power pins into a single 8-pin row.
Diverse Applications – Small Screen, Big Impact
Thanks to its compact size, 400 cd/m² brightness, and wide viewing angle, this Arduino Display SPI module is widely used in:
- Industrial Control & Smart Instruments – Small factory automation panels, portable digital multimeters, handheld gas/inspection detectors.
- Wearables & Health Monitoring Devices – DIY smartwatches, portable blood pressure monitors, fingertip pulse oximeters, fitness trackers.
- IoT & Smart Home Nodes – Desktop weather stations, router status panels, smart lock displays, environmental sensor terminals.
Can this display be used with a 5V Arduino UNO? What happens if connected directly?
The module’s typical VCI voltage is +3.2V ±0.2V, making it a 3.3V logic device. Connecting it directly to a 5V Arduino UNO/Mega2560 without protection will expose the ST7735S driver to 5V logic levels, potentially exceeding its maximum voltage rating and causing overheating or permanent damage. Therefore, when using with a 5V system, you must add 1kΩ–2kΩ current-limiting / voltage-dividing resistors on all signal lines (SCL, SDA, RESX, D/CX, CS), or use a dedicated level shifter (e.g., 4504 or 4050) for 5V → 3.3V logic level conversion.
