The Pine64 Ox64 is a tiny single-board computer that looks a lot like a Raspberry Pi Pico. But while Raspberry Pi’s tiny board is powered by an RP2040 microcontroller, the Ox64 has a dual-core RISC-V processor, 64MB of embedded RAM, and support for up to 128Mb of flash storage plus a microSD card for additional storage.
Pine64 introduced the Ox64 in October, and it’s now available for purchase for $6 to $8. The entry-level model has just 16Mb of flash storage and supports RTOS, while the $8 version has 128Mb plus a microSD card reader and support for Linux-based software. Overall, the little device blurs the lines between a microcontroller and a (very low power) single-board PC.
The board is designed to be a small, inexpensive single-board computer with a RISC-V processor that’s aimed at developers. At its heart is a Bouffalo Lab BL808 processor, which features:
- 1 x Alibaba T-Head C906 64-bit CPU core @ 480 MHz
- 1 x Alibaba T-Head E907 32-bit CPU core @ 320 MHz
- 1 x Alibaba T-Head E902 32-bit core @ 150 MHz
The little board also supports WiFi 4, Bluetooth 5.0, and 802.15.4 (Zigbee) wireless protocols. The board is designed for use in smart home products, among other things.
The board has two USB Type ports: a USB Type-C OTG port and a micro USB port that’s for power only – it works with a 5V/0.5A power supply.
There’s also a 40-pin expansion header with GPOIO, SPI, I2C, I2S, and UART, as well as support for a MIPI CSI camera. Pine64 plans to offer 10/100 Ethernet, audio, and camera adapter boards in the future and notes that the system features H.264 and MJPEG encoders, a JPEG decoder, and an audio subsystem.
Pine64 began shipping boards to developers in October before making them more widely available via the Pine64 Store. But while I see instructions for installing Linux on the BL808 in the Pine64 Wiki, it doesn’t look like RTOS builds are available for the $6 version yet.
At this point it’s safe to say that both versions are still probably best suited to developers.
