The device runs RetroPie, a popular emulation-focused operating system, and supports WiFi connectivity. Its compact dimensions (136.4 x 67.5 x 16.8 mm) and 3500mAh battery make it suitable for on-the-go gaming.

Who It Is For

The GPM280 CM4 is ideal for retro gaming enthusiasts who appreciate a compact, dedicated device for emulating classic consoles up to the N64 and Nintendo DS era.

Buying Notes

Pricing is estimated between $100 and $150, with an initial launch price of $150. Released in September 2021, availability may vary. The device uses an external MicroSD for storage, so consider purchasing a high-capacity card. No video output is included, limiting gameplay to the built-in screen. The mono speaker and lack of rumble or cooling features are trade-offs for its size and price point.
