BeepBerry handheld Linux computer drives 2.7-inch display with Raspberry Pi Zero W

Good news! The PocketCHIP handheld Linux computer is back! OK, not quite but that’s what the Raspberry Pi Zero-powered BeepBerry reminds me of with a Blackberry-like keyboard, a small 2.7-inch display, and a 2,000mAh LiPo battery for power.

The BeepBerry is another open-source hardware design from SQFMI, who previously did the Watchy ESP32 E-Ink smartwatch, that runs Raspberry Pi OS Lite on the Raspberry Pi Zero/Zero W, and also includes a Raspberry Pi RP2040 to handle the keyboard and peripherals.


BeepBerry specifications:

  • SBC – Raspberry Pi Zero board with a Broadcom BCM2835 ARM11 processor @ 700 MHz, VideoCore IV GPU, or Raspberry Pi Zero W with WiFi and Bluetooth
  • Storage – MicroSD card slot
  • Display – Ultra-low power high contrast 2.7-inch Sharp Memory LCD with 400 x 200 resolution
  • User input – QWERTY tactile keyboard w/ backlight and touchpad based on Solder Party BB Q20 Keyboard
  • USB – USB-C programming & charging
  • Expansion – 3x 10-pin GPIO headers (unpopulated)
  • Debugging – SWD header
  • Misc
    • Programmable RGB LED for notifications
    • Programmable side button
    • Raspberry Pi RP2040 MCU (for keyboard and peripherals control) with 16MB flash
    • Power switch and PMIC
  • Battery – 2,000mAh LiPo battery
  • Dimensions – 104 x 74 x 15 mm

The name of the device is derived from the Beeper messaging app for which the BeepBerry is an ideal platform. You’ll also find documentation, now work-in-progress, on the SQFMI website.

The BeepBerry ships with mounting screws and a 2,000 mAh LiPi battery, and the Raspberry Pi Zero W is an option. You can pre-order the handheld Linux computer on the company’s shop for $79 without SBC, or $99 with a Raspberry Pi Zero W. The former is expected to ship in August of this year, and the latter in September.
