FriendlyElec has launched a $35 open-spec “NanoPi K1 Plus” SBC. The new NanoPi K1 Plus is a media-rich board, that switches from the Amlogic S905 SoC (found on the Odroid-C2) to an Allwinner H5 SoC, which is used in several other NanoPi boards. Both the SoCs have 4x Cortex-A53 cores and a Mali-450 GPU, but the H5 has a lower clock speed of 1.4GHz instead of 1.5GHz.
The new board has almost similar footprint to NanoPi K2, 85 x 56mm. It has an identical feature set and layout as the RPi 3 and Odroid-C2. FriendlyElec has swapped out the K2’s WiFi/Bluetooth module for a 2.4GHz WiFi-only chip and has reduced its HDMI 2.0 port to an HDMI 1.4 that has its 4K support only at 30fps max. The K1 Plus has also decreased one of the USB 2.0 host ports, leaving 3x USB 2.0 ports total along with a micro-USB OTG port with power input support. The previous DC-in jack has been removed.
On the better side, the K1 Plus add some multimedia features. There’s a new DVP camera interface, an onboard mic, and a 3.5mm audio jack that also outputs the CVBS signals. CVBS was previously available only via the continuing, Raspberry Pi-compatible 40-pin expansion connector.
There are 2GB RAM, a microSD slot, eMMC socket, and GbE port. Once again, you get an IR receiver, a heatsink, and a debug header, among other details. The open-spec board is available with schematics and other documentation, as well as images for Armbian and the Ubuntu Core based OS, FriendlyCore.
