These two variants are powered by the Rockchip RK3568 SoC as in the Tinker Board 3N seen last August, featuring a Quad-core Arm Cortex-A55 CPU and an Arm Mali-G52 GPU.

Memory configurations vary across the models: the 3N Plus is available with Dual-CH LPDDR4/LPDDR4X in 2GB and 4GB options, while the 3N and 3N Lite also offer an 8GB option. All models come with the option of up to 64GB of eMMC storage and include a Micro SD card slot. Additionally, the 3N and 3N Plus models are equipped with 16MB of SPI Flash.

For connectivity, the 3N Plus and 3N come with dual Realtek RTL8211 Ethernet controllers, while the 3N Lite features a single controller. All models support Wi-Fi 5 and Bluetooth 5.0. Additionally, PoE PD compatibility is available on the 3N Plus and 3N, enhancing their networking capabilities.

Key distinctions in the Tinker Board 3N series include the inclusion of an M.2 B key 3042/3052 with a nano-SIM slot in the 3N Plus and 3N variants. This slot supports 4G/5G connectivity and SSDs, utilizing PCIe 3.0 x1, USB 3.0, and USB 2.0 interfaces. However, this feature is not available in the Lite version. Additionally, the 3N Plus and 3N models do not include the CAN Bus 2.0B interface via a 3-pin header.

All variants include the following display options: HDMI (up to 4096 x 2160 @ 60 Hz), LVDS (up to 1920 x 1080 @ 60 Hz, Dual-link), and eDP (up to 2560 x 1600 @ 60 Hz). For audio and USB connectivity, the boards are equipped with a 3.5mm audio jack, a 4-pin stereo speaker output (4Ω, 2x 3W), and a 1-pin S/PDIF integrated into the GPIO header.

Each board in the Tinker Board 3N series is designed for specific temperature ranges. The Plus variant operates effectively between -40°C and 85°C, making it suitable for extreme conditions, while the standard 3N and Lite variants are optimized for a range of 0°C to 60°C, ideal for typical environments. All boards can be powered using a DC Barrel power input jack supporting 12V to 24V, or through a 4-pin power-in header.
