While it may be hard to buy a Raspberry Pi these days, there are various alternatives with the Raspberry Pi 3/4 form factor, including Pine64’s Quartz64 Model B SBC powered by a Rockchip RK3566 processor that has just launched for $59.99 with 4GB RAM.
The Quartz64 Model B is a smaller version of the Quartz64 Model A launched earlier this year, that comes with HDMI 2.0a and MIPI DSI display interfaces, a MIPI CSI camera interface, Gigabit Ethernet, WiFi 5 and Bluetooth 5.0, as well as several USB 2.0/3.0 ports, and of course, a 40-pin Raspberry Pi compatible GPIO header.
- SoC – Rockchip RK3566 quad-core Cortex-A55 processor up to 1.8 GHz with Arm Mali-G52 GPU supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1, 0.8 TOPS NPU for AI acceleration
- System Memory – 4GB LPDDR4
- 128 Mbit SPI Flash
- optional eMMC module from 16GB up to 128GB capacity
- bootable SDHC/SDXC MicroSD card up to 2TB
- Video Output / Display Interfaces
- HDMI 2.0a up to 4Kp60
- 2-lane MIPI DSI up to 1080p
- Camera I/F – 2-lane MIPI CSI camera Interface up to 5MP
- Audio – 3.5mm audio (headephone+mic) jack
- 10/100/1000Mbps Gigabit Ethernet RJ45 port with PoE expansion
- Dual-band 802.11b/g/n/ac WiFi 5 & Bluetooth 5.0 via Ampak AP6256 module
- USB – 2x USB 2.0 host ports, 1xUSB 3.0 host port
- 40-pin GPIO header with I2C, SPI, and UART
- mini PCIe socket
- Misc – RTC battery connector, IR receiver
- Power Supply – 5V/3A DC input via 3.5/1.35mm DC barrel jack
- Dimensions – 85 x 56 mm
Other supported operating systems are Android 11, Arch Linux Arm, gwipeout’s Quartz64 CI (Debian Installer + buildroot rescue), and NetBSD (relying on Tianocore EDK II UEFI port) of all which you can find in the Wiki. LAKKA OS for retro-gaming might be ported to the board as well. Mainlining is also in progress with initial support for Quartz64 Model A and B, and the SOQuartz module to be introduced into Linux 5.19, as well as the VOP2 driver for HDMI, but the DTS change for the latter will somehow only get accepted in Linux 5.20.
