As previously mentioned, work was in progress to design development boards based on Rockchip processors. Radxa Rock and Radxa Rock Lite, 2 boards powered by Rockchip RK3188, are now available to early developers, and the final versions will soon be broadly available.
Here are the boards specifications:
- SoC – Rockchip RK3188 ARM Cortex-A9 quad core @ 1.6Ghz + Mali-400 MP4 GPU
- System Memory – 2GB DDR3 @ 800Mhz (1GB DDR3 @ 800Mhz for Lite version)
- Storage – 8GB Nand Flash (4GB Nand Flash for Lite version) + micro-SD SDXC up to 128GB
- Video Output – HDMI 1.4 up to [email protected], andAV output
- 10/100M Ethernet port
- WIFI 150Mbps 802.11b/g/n with antenna
- Bluetooth – Bluetooth 4.0 (Not in Lite version)
- Audio I/O – Audio S/PDIF, headphone jack
- USB – 2x USB 2.0 host port, micro USB OTG
- Debugging – Serial Console
- Misc – IR sensor, power key, recovery key, reset key, 3 LEDs, RTC
- Expansions Header -80-pins including GPIO, I2C, SPI, Line in, USB 2.0, PWM, ADC, LCD, GPS… etc
The boards will support both Android and Linux. The latter with limitations such as lacking video hardware acceleration (VPU), at least until some workaround (libhybris?) are found. The early schematics (PDF) can also be downloaded for reference.
There are currently 100 working samples that early developers can acquire for half price now. The final retail is not fully confirmed, but I’ve been told Radxa Rock should go for $89, and Radxa Rock Lite for $69, which look like decent prices.
