Description
This board requires a quality power supply capable of at least 5V/3A (15W) over USB-C, or a USB-C PD/QC adapter (9V/2A or 12V/2A). A 5V/1A or 5V/2A phone charger will not work and will cause boot failures or instability.
Wi-Fi & Bluetooth need an external antenna. Wireless on this board is routed through the U.FL connector at the rear of the board — without an antenna fitted, Wi-Fi and Bluetooth range is very limited. We stock a U.FL → SMA antenna adapter separately, and one is already included if you order the Heatsink and Case kit.
Wi-Fi is 2.4 GHz only. The onboard wireless connects to 2.4 GHz (802.11 b/g/n) networks only — it does not support the 5 GHz band. Make sure your router broadcasts a 2.4 GHz SSID.
These items do not come in retail packaging. Items are sent in protective anti-static bags.

Hexa-Core Performance
Rockchip RK3399 — big.LITTLE compute in a Pi-class form factor
Two high-clocked A72 cores tackle the heavy lifting while four efficient A53 cores keep everything else responsive — with a Mali GPU that drives 4K media, M.2 NVMe storage, dual display, and a full 40-pin GPIO header.
