Linux on a Raspberry Pi in the Palm of Your Hand
Who hasn’t dreamed of a computer the size of a calculator they could use to play games or carry out system-administration tasks when they’re on the go? Who doesn’t want a way to keep busy or stay entertained on a bus or a train or a subway? (A way that does not require balancing expensive hardware on their lap while repeatedly elbowing their neighbors…) Who wouldn’t enjoy leaving their bag or backpack at home more often? Scenarios like this speak to us, here at Morpheans, so we decided to make them a reality—with the ShaRPiKeebo nanocomputer.
As the culmination of the BlakRPi range of mini-computers we’ve been developing over the past four years, ShaRPiKeebo comes with the following…
Features & Specifications
- 2.7", 400x240-pixel, low-latency, energy-efficient LS027B7DH01 SHARP Memory Display
- Built-in, QMK-compatible USB QWERTY keyboard with 56 keys
- Can function as an external keyboard when attached to another device (such as a rack server)
- Two four-button D-pads for gaming
- Five buttons, controllable via (up/down) GPIO voltage detection
- Four independently controlled LEDs, programmable using classic GPIO commands in C++ or Python
- Long-range, 433-MHz radio transceiver (currently RFM95; working on upgrade to CE-marked RakWireless chip)
- On-board battery-management and charging module that draws power through USB Type-C
- A JST connector for a LiPo battery
- UART and I²C available through GPIO for external 3.3 V modules (GPS, a 4G or 5G modem, etc.)
- ISP programming port available for QMK-keyboard flashing or upgrades
- Form factor
- SBC connector: 2x40-pin connector for Raspberry Pi Zero W or 2W SBCs
- Dimensions: 66 x 115 x 20 mm
- Weight: Under 100 g
Why does this say 433 MHz, but the crowd supply link switched to the 33cm band (902-928 MHz)? I want something that can interact with my Baofeng (or maybe even the cheap FRS radios, lol). Can I retune it back to the 70cm band?
