The LattePanda 3 Delta is a small x86 Single Board Computer (SBC) with an Arduino platform onboard. In a little bigger size factor than a Raspberry Pi 4, the 3 Delta has a better CPU and more high-speed ports than the Pi. The 64GB eMMC can be upgraded with two more M.2 drives, and the wireless connection is as fast as it gets thanks to a Wi-Fi 6 module.
The device comes with Windows 10 Pro and a USB type-C interface for power, display, and USB connectivity. Because of its inbuilt ARM microprocessor and multiple headers that give a combination of analog and digital interfaces, the 3 Delta is ideal for experimenting.
The LattePanda 3 Delta is available with two kinds of Windows 10 Pro licenses. The baseline consists of an unactivated license and costs $279. For an extra $60, the Windows Enterprise edition adds Cortana and Windows Hello. DFRobot, which makes the LattePanda SBCs, offers a case for $19.
The LattePanda 3 Delta, which ships in plastic clamshell, comes with two Wi-Fi antennas, a user manual, and a compact 45W USB Type-C power adapter. The PCB measures 8cm x 12.5cm x 1.6cm and weighs 110g. The heatsink and fan cover almost the entire surface of the board except for the connectors. Four 3.2mm corner holes secure the board to a case using screws.
The SBC contains a powerful quad-core Intel Celeron N5105 processor that can boost up to 2.90 GHz. Compared to the Pi’s CPU, the N5105 should offer more than twice the processing power. An 800MHz Intel UHD GPU, 8GB DDR4, and 64GB eMMC assist the CPU in its operation. An Intel i211 1Gb Ethernet chip and a Wi-Fi 6 module provide network connectivity. Components of a Leonardo Arduino are soldered onboard next to the main CPU.
The 3 Delta offers many high-speed interfaces, including two USB3.2 Gen 1 and one Gen 2 Type-A. The most used connector is the USB Type-C connector on the right side, which provides a Display Port connection and supplies power. An HDMI 2.0b connector, a Gigabit LAN port, and an audio socket are also on the right and extend the SBC to a full PC capable of a dual 4K screen configuration. The bottom of the PCB holds three high-speed interfaces; two are M.2s for SATA III and NVMe, while the last is an FHD eDP output.
The CPU fan speed is usually quiet except for an occasional low hum. The PCB will get hot with all accessories installed and should be placed in a case to prevent any short circuits.
Two rows of 2.54mm headers on the top and bottom of the board contain various low-speed interfaces such as RS232, speaker output, I2C, and SPI. The last two interfaces are accessible only through a Python library. Most pins are 5V compatible except for the I2C, which supports only 1.8V.
