thingiverse

This is a 2-in-1 laptop based on Raspberry Pi 4. Specifications: * CPU: ARM Broadcom BCM2711 * RAM: 1, 2, 4 or 8 GB LPDDR4 * Hard-disk: MicroSD up to 64GB (replaceable without disassembling the laptop) * Display: 7" IPS 1024x600 * Capacitative multi-touchscreen * Wireless: 2.4 GHz and 5.0 GHz IEEE 802.11ac * Bluetooth: 5.0, BLE * Webcam: 2 Mpixel * Backlit keyboard with click * Multitouch trackpad * Battery: 3-cell lithium-ion battery * Ports: 2x USB 3.0, 1x USB 2.0, 1x Gigabit Ethernet, 1x HDMI, 1x Audio out, 1x 40 pin GPIO header * External sizes: 183.4x138.1x43.5 mm (7.22x5.44x1.71 inch) * Weight: 962 g (33.9 oz) 3D printing of this project is straightforward but the electronic wiring are extremely challenging. You need to have good skills in soldering electronic components. I am currently working on designing a PCB to simplify connections. I was unable to get the XL4015 charger into the laptop so I will put it together with the power supply. The current firmware only provides the ON/OFF function. I am working on the firmware for battery and fan management.
