Two small round LCD screens side by side on a green circuit board

Bipra

Bipra 0.71inch Double Eye Round LCD Display Module 2 in 1 accessory

SKU CH-21AP-DJ22R

Dual 0.71 inch round IPS screens with 160x160 resolution and 65K colours connect via SPI to Raspberry Pi Pico or ESP32 boards

  • Twin 0.71 inch round screens expand visual output
  • 160×160 IPS panels give wide viewing angles
  • 65K colours render vivid graphics on each display
  • SPI bus reduces GPIO usage on Pico and ESP32 boards
  • 3 V or 5 V supply simplifies power integration

Dual Round LCD Module

This Bipra accessory combines two 0.71inch round IPS displays into a single module for microcontroller projects. Each panel shows 160x160 resolution with 65K colours and a wide viewing angle. The GC9D01 driver is embedded on the board. It targets makers adding compact visual output to Raspberry Pi Pico or ESP32 builds.

SPI Interface Limits

Communication uses an SPI bus that minimises the required IO pins on the host controller. The module operates at 3.3V or 5V logic levels without external level shifting. No other interface or protocol is supported by the hardware. Builders needing parallel, I2C or higher-bandwidth display links must choose a different panel.

160x160 Resolution

The fixed 160x160 pixel grid per eye determines the amount of graphical detail each screen can render. This resolution suits simple icons, sensor readouts or basic animations. Projects requiring text-heavy layouts, detailed graphics or larger viewing areas will find the pixel count insufficient.

Questions about this item

Should I pick the single-eye or the double-eye module for my project?

The listing describes a double-eye module containing two 0.71inch round IPS displays, each 160x160 pixels with 65K colours, driven by an embedded GC9D01 controller over a single SPI bus.

How much space does the 160x160 resolution actually give me on a 0.71inch round screen?

Each round panel shows 160 by 160 pixels at 65K colours, so you have a compact but sharp canvas for icons, gauges or short text within a 0.71inch diameter.

What does the SPI interface limit in practice?

SPI keeps the pin count low — only the standard SPI lines plus chip-select are needed — and the module accepts both 3.3V and 5V logic, making it straightforward to wire to a Pico, Pico W, Pico 2, Pico 2 W, ESP32 or Arduino board.
