GPM280 CM3 (WaveShare) Handheld Review

Overview

The GPM280 CM3, developed by WaveShare, is a handheld gaming device designed for retro enthusiasts. It runs on an open-source operating system and is powered by a Broadcom BCM2837 processor with a quad-core Cortex-A53 CPU clocked at 1.2 GHz. The device features 1 GB of DDR2 RAM and relies on external MicroSD storage. Its 2.8-inch IPS display offers a 4:3 aspect ratio with a resolution of 640x480, resulting in a pixel density of 285.71 PPI. The handheld is available in a FC gold-red plastic shell and includes WiFi connectivity, a mono speaker, and a 3.5mm headphone jack. A 1500 mAh battery powers the unit, with ventilation holes for heat dissipation.

Who It Is For

The GPM280 CM3 is ideal for retro gaming fans who want a dedicated device for playing classic titles from the SNES and PS1 era. It can handle SNES FX and 3D PS1 games at 60 FPS, but N64 and NDS games may be playable but not always smooth. It suits users comfortable with open-source systems and willing to manage storage via MicroSD cards.

Buying Notes

Priced between $100 and $150 (launch price $150), the GPM280 CM3 offers good value for its performance in lower-end emulation. However, consider its limitations with N64 and NDS. The plastic build and mono speaker are basic, but the WiFi connectivity adds convenience. No video output is available. Check for availability and current pricing from WaveShare or authorized retailers.
