piBrick Pocket-CM5 is an open-source handheld computer built around the Raspberry Pi Compute Module 5. Created by Ahmad Amarullah, the device combines a custom PCB, 3D-printed enclosure, and smartphone-sized footprint measuring 80 x 145 x 19.6 mm. The front is dominated by a 3.92-inch AMOLED display with a 1080 x 1240 resolution and 90Hz refresh rate, protected by custom Asahi tempered glass. Full-size HDMI and micro-HDMI outputs allow the handheld to function as a portable workstation when connected to an external display.
A BBQ20 keyboard provides a compact QWERTY layout paired with an integrated trackpad inspired by BlackBerry devices. Two rotary encoders and five programmable buttons add physical controls beyond the touchscreen interface. The system supports NVMe SSD storage in 2230 and 2242 formats and runs a full Linux desktop environment on the Compute Module 5 platform.
