Technical data sheet for the RoboPeak Mini USB Display, a 2.8‑inch resistive touchscreen with USB power and 320×240 resolution.
The RoboPeak Mini USB Display is a low‑cost, USB‑powered 2.8‑inch resistive touchscreen module. It features a 320×240 pixel LCD, up to 100 fps refresh, and an on‑board STM32 Cortex‑M3 microcontroller with native USB support.
The manual provides an overview of functions, pin definitions, mechanical dimensions, quick‑start connection steps, touchscreen calibration, and guidance for secondary development using the open‑source Linux driver and SDK. This manual is written in Chinese.
| Display resolution | 320×240 pixels |
|---|---|
| Color depth | 16‑bit (65,500 colors) |
| Screen size | 2.8 inch resistive touchscreen |
| Power supply | USB‑bus power 4.8‑5.2 V, 200 mA |
| Dimensions | 74 mm × 60.5 mm |
The display draws power directly from the USB connection, requiring 4.8‑5.2 V at up to 200 mA, so no external power supply is needed.
All data is transferred over a single Micro‑USB connector that provides both power and USB communication.
