Product Overview
The FZ177-128160 is an industrial-grade 1.77 inch Thin-Film-Transistor Liquid Crystal Display module with a 128x160 portrait resolution (28.03 (W) x 35.04 (H) mm active area inside a 34.0 (W) x 45.8 (H) x 2.4 (T) mm outline). The panel uses a transmissive TFT cell with a wide 12:00 viewing direction and a pixel pitch of 0.219 x 0.219 mm, which together deliver 262K (RGB) vivid color reproduction and crisp text rendering. The module is built around the widely-adopted Sitronix ST7735S controller, exposed to the host through a SPI 4W (4-wire serial) bus that requires only four MCU GPIO pins. The FPC is a 14-pin (FPC) plug-in tail, and the breakout board ships a friendly 8-pin (host breakout) host connector for direct hook-up to 3.3 V microcontrollers such as ESP32, STM32, Arduino Mega, RP2040 and nRF52. Backed by Shenzhen FuZheng Photoelectric's more-than-a-decade display manufacturing experience, every FZ177-128160 unit ships with stable production quality, competitive factory pricing, and full OEM/ODM customization (FPC length, pin-out, touch-panel integration, polarizer treatment).

FAQ — Frequently Asked Questions
Q1: Which microcontroller platforms does the FZ177-128160 support?
The FZ177-128160 uses the Sitronix ST7735S controller, which is natively supported by every popular open-source graphics library: Adafruit_ST7735 (Arduino), TFT_eSPI (ESP32 / ESP8266 / RP2040), U8g2 (Arduino / STM32 / ESP32), lv_port_st7735 (LVGL 8.x), and the ST Microelectronics ST7735 BSP. Reference schematics and initialization code are provided with every sample order.
Q2: How many GPIO pins are required to drive the display?
Only 4 GPIO pins are required for data: SCK (serial clock), SDA (serial data), CS (chip select), and DC (data/command select, also called A0 or RS). A 5th pin is recommended for /RESET, and an optional 6th pin (BL) is used for backlight PWM dimming. This makes the FZ177-128160 ideal for low-pin-count MCUs such as ESP32-C3, nRF52810, RP2040 and ATmega328P.
Q3: What is the difference between the 14-pin FPC and the 8-pin breakout?
The 14-pin FPC is the LCM-side flexible printed circuit that carries all display signals plus the backlight power pins (LED+, LED-) and several NC/GND pins. The 8-pin breakout is the host-side connector that exposes only the signals an external MCU needs: VCC, GND, SCL, SDA, RES, DC, CS, BL. Most users wire the host MCU to the 8-pin breakout with a standard 2.54 mm dupont cable.
Q4: What is the recommended backlight driving condition?
The backlight is a single LED string with LED+ at 3.0 ~ 3.4 V and LED- as the cathode. A typical drive current of 15 ~ 30 mA produces a luminance of 250 ~ 350 cd/m². For PWM dimming, drive the LED- pin through an N-channel MOSFET (such as 2N7002) with a 1 kHz ~ 10 kHz PWM signal from the BL pin.
Q5: What is the operating temperature range? Is it suitable for outdoor use?
The standard operating temperature is -20 ~ +70 °C and storage temperature is -30 ~ +80 °C, which covers most indoor consumer, industrial and portable scenarios. For outdoor or direct-sunlight deployments we recommend a customized high-brightness variant (>800 cd/m² backlight) and a UV-resistant polarizer. Contact our sales team for outdoor-grade customization.
Q6: Do you provide initialization code, datasheet, and reference schematics?
Yes. With every sample order we provide the full datasheet (PDF), the ST7735S initialization code, recommended reference schematic for the 8-pin breakout, and the SPI porting guide for popular MCU platforms. Our engineering team can assist with bring-up questions during your evaluation.
Q7: What is the lead time and minimum order quantity (MOQ)?
Standard FZ177-128160 variants (no-touch, 14-pin FPC + 8-pin breakout) are kept in stock for sample orders. Mass-production MOQ is typically 500 ~ 1,000 pcs depending on configuration. Lead time is 10 ~ 15 working days for stocked variants and 20 ~ 30 working days for custom variants. Contact our sales team for an exact quote.
