The LattePanda 3 Delta represents a significant evolution in the single-board computer landscape, distinguishing itself not merely as a compact desktop replacement but as a hybrid platform that seamlessly integrates the power of a full x86 personal computer with the tactile control capabilities of an Arduino microcontroller. Developed by DFRobot, a Shanghai-based robotics company, this pocket-sized device was announced in November 2021 and entered global retail availability in August 2022. It is important to clarify a common misconception regarding its hardware lineage: unlike some earlier iterations or misattributed specifications, the LattePanda 3 Delta is powered by the Intel Celeron N5105 processor, part of the Jasper Lake family. This is a quad-core, quad-thread processor manufactured on a 10-nanometer process, featuring a base frequency of 2.00 GHz that can burst up to 2.90 GHz. For those unfamiliar with these terms, the core count refers to the number of independent processing units within the chip, while the thread count indicates how many sequences of instructions it can handle simultaneously; in this case, the 4C/4T configuration is designed for efficiency, operating with a Thermal Design Power of just 10 watts. This low power consumption is crucial for a device of this size, allowing it to run quietly and coolly, though it does rely on an active cooling system with a redesigned fan that offers a 50 percent larger cooling area compared to its predecessors to sustain performance under load.

Memory and storage are fixed at the factory, with the board coming equipped with 8 GB of LPDDR4 RAM running at 2933 MHz. LPDDR4 is a low-power double data rate memory standard, optimized for mobile and embedded applications where energy efficiency is paramount. Storage is provided via 64 GB of onboard eMMC 5.1, which is essentially a solid-state drive soldered directly onto the motherboard, offering faster and more reliable performance than traditional SD cards. However, for users requiring more space or faster speeds, the board includes an M.2 Key M slot that supports PCIe 3.0 x2 NVMe SSDs, allowing for significant expansion. A second M.2 Key B slot is available for SATA III drives or, notably, for 4G or 5G cellular modems, supported by a dedicated SIM card slot. This cellular readiness makes the LattePanda 3 Delta particularly attractive for remote IoT deployments where wired internet is unavailable. Connectivity is further enhanced by an Intel AX201 wireless module, which provides Wi-Fi 6 support and Bluetooth 5.2. Wi-Fi 6, also known as 802.11ax, offers better performance in congested networks and lower latency compared to older Wi-Fi standards, while Bluetooth 5.2 ensures robust connections for peripherals. Wired networking is handled by an Intel Gigabit Ethernet controller that supports Wake-on-LAN, allowing the device to be remotely powered on for maintenance or updates.

One of the most defining features of the LattePanda 3 Delta is its onboard co-processor: a Microchip ATmega32U4-MU. This is not a simple GPIO expander but a full-fledged Arduino Leonardo-compatible microcontroller. This distinction is vital for developers, as it means the board can be programmed using the standard Arduino IDE and libraries, with its own reset button and USB serial enumeration. This allows the main x86 processor to communicate with the microcontroller via a virtual COM port, enabling complex projects where high-level logic runs on Windows or Linux while real-time hardware control, such as reading sensors or driving motors, is handled by the dedicated microcontroller. DFRobot supports this integration with the "pinpong" library, a Python-based tool that simplifies controlling the Arduino pins from the host operating system, bridging the gap between high-level computing and low-level electronics. The board exposes a rich set of General Purpose Input/Output (GPIO) pins, including 24 digital I/O pins and 7 PWM pins. PWM, or Pulse Width Modulation, is a technique used to simulate analog outputs by varying the width of digital pulses, which is commonly used for controlling the brightness of LEDs or the speed of motors. While the official documentation confirms the pinout, the exact logic voltage levels (3.3V vs 5V) for every pin are not explicitly detailed in all public datasheets, so users should consult specific tutorials for precise electrical characteristics.

The LattePanda 3 Delta is designed with industrial reliability in mind, featuring several robustness enhancements. It includes a hardware watchdog timer implemented in the IT8613E Super I/O chip. A watchdog timer is a safety mechanism that automatically resets the system if it freezes or fails to respond, which is critical for unattended kiosks or remote installations. The board also supports a Trusted Platform Module (TPM 2.0) for hardware-based security, useful for encrypting data and securing boot processes. Power management is flexible, with dual inputs: a USB Type-C port that supports Power Delivery (PD) and a 4-pin JST DC connector. The system can automatically failover between these two power sources without interruption, ensuring continuous operation. An optional UPS Hat accessory is available, which uses three 18650 batteries to provide backup power and communicates with the host via the HID-UPS protocol, allowing the operating system to shut down gracefully during power outages. The video output capabilities are equally impressive for a device of this size, supporting up to three simultaneous displays through HDMI 2.0b, DisplayPort 1.4 via USB-C, and an internal eDP connector for touch-capable panels. This multi-display support makes it suitable for digital signage and control room applications.

Software compatibility is broad, as the device is essentially a standard x86-64 PC. It ships with Windows 10 Pro or Windows 10 IoT Enterprise, depending on the SKU, but officially supports Windows 11 and Ubuntu 22.04 LTS. The official documentation provides step-by-step guides for installing Ubuntu, noting that users may need to update the BIOS to resolve boot order issues when dual-booting. It is worth noting that early reviews from late 2021 and 2022 observed some software maturity issues with 4K video playback on Jasper Lake platforms, though these were largely attributed to driver and OS updates rather than hardware defects. Users should also be aware of specific quirks documented in the official FAQ: for instance, the fan does not spin when the device is cold but only activates at a specific temperature threshold, which can be mistaken for a hardware failure. Additionally, a flat CMOS battery (CR927) can cause slow boot times or disable the auto-power-on feature, although community workarounds using the Arduino pins have been developed to mitigate this. While the board is highly capable, it does not have a publicly available full schematic, limiting deep hardware-level debugging for advanced users. Nevertheless, with its combination of x86 processing power, genuine Arduino integration, and industrial-grade features like dual power inputs and watchdog timers, the LattePanda 3 Delta stands out as a versatile tool for makers, engineers, and developers looking to bridge the gap between desktop computing and physical computing in a compact, reliable form factor.

Code library — examples written for this board

clignotante.py Python
The LattePanda pattern: the Python script runs on the x86 PC, the physical pin lives on the ATmega32U4, and PinPong bridges them in one line. The Arduino world becomes a PC library.
bouton.py Python
The physical button becomes a PC event: 50 Hz polling on the Python side, pull-up handled by the MCU. The ideal trigger for the heavy processing only the x86 can do.
servo.py Python
The servo on the header obeys a Python function: the library translates angle into 50 Hz PWM on the 32U4's timer. The PC adds what Arduino cannot: camera, AI, database.
analogique.py Python
The ATmega's 10-bit ADC flows into a timestamped CSV on the PC disk: a €20 acquisition card with unlimited storage, calibration corrections in pandas instead of C.
respiration.py Python
The 32U4's PWM follows a sine computed on the PC: the ramp is perfectly smooth because the x86 has all the time to compute 50 points per second. The visual demo of the host-MCU couple.
neopixel.py Python
The 800 kHz WS2812 frame is generated by the MCU, the animation comes from Python: the addressable strip joins the PC's scripting world. Mood lighting drivable by camera or music.
pont_serie.py Python
The 32U4 stays an autonomous Arduino: this PWM-control sketch, driven by pyserial from the host, shows the duo in raw form — no library, protocol of your choice. The bridge every project ends up usin…
journal_systeme.py Python
The LattePanda is a PC: psutil yields temperature, load and disk like any server. A home-made CSV journal watches the machine itself — the first reflex before loading it with compute.
tableau_bord.py Python
The duo's best in 25 lines: the MCU pin and the PC counters merge into one auto-refresh HTML page. Any phone on the network becomes the machine's interface.
clavier_media.ino Arduino
The 32U4 is a full USB device: a header button becomes a media key sent to... the LattePanda host itself. The complete circuit button → HID → system, no wires, no drivers.
