Two new Rockchip mini PCs with external antennas arrive

j22Rockchip has surely picked a winner with its RK3188 SoC CPU design, powering just about every low-cost tablet and mini PC coming out of China at the moment.

Two more have just appeared on the web, just known as the J21 and J22.

According to, the J21 is a dual-core mini PC that looks a little like the DM918 with its twin Wi-Fi antenna sticking out like exhaust pipes at the back. Looking at the specs from retailer Pandawill, it’s powered by Rockchip’s original RK3066 SoC CPU and includes 1GB of RAM and 8GB of on-board flash.

The J22 is the same chassis but with the RK3188 quad-core SoC CPU and 2GB of RAM.

Otherwise, they look pretty much identical. While you get the standard 802.11b/g/n Wi-Fi standard support through the two external antenna, it’s not clear whether they actually come with Bluetooth or not.

Both units are being sold on Pandawill – the J22 for $79.95; the J21 for $57.

The chassis includes MicroSD card slot, with support for up to 32GB cards. You also get a male HDMI plug and two USB ports – a type-A host port and a microUSB OTG option.

The RK3188 quad-core SoC CPU is a quad-core Cortex A9 design manufactured with a more modern and power-efficient 28-nanometre process and uses ARM’s reference Mali-400 MP4 quad-core GPU engine. The older RK3066 also uses two Cortex A9 cores but is manufactured at 40-nanometres. It also gets AMR’s quad-core Mali-400 MP4 GPU setup.
