1 Idea3399 Introduction
1.1 Summary
Idea3399 is equipped with RK3399 Cortex-A72 + Quad Cortex-A53 processor coupled with 4GB
RAM, 8GB eMMC, an mPCIe slot for cellular connectivity, and other interactive interfaces geared
towards to AI and IoT Applications.
Display features include a mDP port, HDMI and MIPI LCD. Idea3399 adopts ALC5651 dual I2S
interface audio codec that supports analog/digital input. The 2x USB3.0 Type C can be converted to
HDMI/USB3.0/USB2.0. In addition, Type C0 also can be used for debugging.
The board is available with a WiFi/BT module with dual-band 802.11ac/a/b/g/n and Bluetooth 4.1
connectivity.
The Idea3399 SBC is equipped with a 4G model(optional) that delivers 100Mbps downlink and
50Mbps uplink data rates, and GSM/GPRS networks to ensure that it can connect even in remote
areas devoid of 4G or 3G coverage. The model also combines high-speed wireless connectivity
with embedded multi-constellation high-sensitivity positioning GPS receiver.
