BIGTREETECH’s Raspberry Pad 5 is a carrier board for the Raspberry Pi Compute Module 4 that gives the tiny computer a 5 inch touchscreen display, Ethernet, HDMI, and USB ports, and a microSD card reader.
Available now for $99, BIGTREEETECH positions the Raspberry Pad 5 as a solution that can be used as a 3D printer controller, smart display, digital photo frame, or smart home accessory. Basically it turns Raspberry Pi’s latest compute module into a full-fledged touchscreen computer.
I’d be tempted to call it a tablet, but the lack of a built-in battery means you’d need to bring along a power bank if you wanted to use the Raspberry Pad 5 + CM4 as a mobile device.
The board measures 121 x 76mm (4.8″ x 3″) and features:
- 5 inch, 800 x 480 pixel capacitive touchscreen IPS LCD display
- 1 x USB Type-C port
- 3 x USB 2.0 ports
- 1 x HDMI port
- 1 x Ethernet port
- 1 x microSD card reader
- 40 pin GPIO interface
- 1 x MIPI-CSI interface
There’s also an onboard real-time-clock that requires a CR1220 lithium coin-cell battery, sold separately.
Note that the $99 price tag doesn’t include a Raspberry Pi Compute Module. BIGTREETECH does sell kits that come with the compute module for $209 and up though if you don’t feel like sourcing the module elsewhere.
The Raspberry Pi Compute Module 4 is a tiny computer with the same quad-core ARM Cortex-A72 processor used in the Raspberry Pi 4. But the 2.1″ x 1.5″ Compute Module isn’t designed to be used on its own – you need to connect it to another board to get features like USB, video out, or power input.
