1. Physical Dimensions & Mounting Holes¶

• Board Dimensions: 88mm × 70mm
• Four Corner Mounting Holes: Identical in position and diameter
• Board Thickness: Approx. 19mm (including component height), slightly thinner than V1, making it compatible with most existing structural designs.

2. External Interface Layout¶

The positions of all core external interfaces listed below are identical to the V1:

• HDMI Port
• 3× USB Type-A Ports
• RJ45 Ethernet Port
• 3.5mm Audio Jack
• MicroSD (TF) Card Slot
• Power and Reset Buttons

What's Improved¶

1. Significant Processor Performance Boost¶

2. Comprehensive Memory & Storage Upgrade¶

3. Remarkable GPU Capability Enhancement¶

4. Changes in Power Supply Requirements¶

To match the increased performance, we have upgraded the power supply system, providing a higher power ceiling and more flexible input methods.

The IOTA requires a higher voltage to drive its powerful performance.

• If you are using the external power port: Your original Micro-USB cable and 5V USB adapter must be replaced with a PD-compliant Type-C cable and a PD power adapter.
• If you are using the internal power connector: Your original 5V DC power source must be replaced with a 10V to 15V DC power source.

5. Changes in Cooling Solution¶

Due to the significant performance increase, power consumption and heat generation have also risen.

You can choose either of the following two heatsinks:

Using the Device Enclosure for Cooling

Using your device's own metal enclosure for passive cooling is a viable option, but it must be rigorously tested and validated to ensure thermal performance is adequate. Please follow these key steps:

• You must use a thermal pad or thermal grease to fill the gap between the processor and the inner wall of the enclosure. This is critical for transferring heat from the processor to the enclosure.
• If your enclosure has limited size or insufficient surface area for heat dissipation, we strongly recommend that you enter the BIOS settings and limit the processor's TDP (PL1) to 6W. This action will significantly reduce peak heat generation, prevent the enclosure from overheating, and ensure long-term system stability.

6. Co-processor Upgrade¶

7. Comprehensive Network Connectivity Upgrade¶

The M.2 E Key slot design gives you the freedom to choose any M.2 2230 Wi-Fi module from Wi-Fi 5 to Wi-Fi 7 based on your needs.

✅ Recommended Pairing: An Intel AX210 or AX211 M.2 module to achieve Wi-Fi 6 + Bluetooth 5.3 high-speed connectivity.

⚠️ Antenna Installation: Dual-band Wi-Fi modules typically require 2 antennas to be connected to ensure stable signal transmission/reception and speed. If you plan to route the antennas to the exterior of a custom enclosure, remember to reserve an additional opening for the second antenna.

8. New Expansion Interfaces¶

The LattePanda IOTA not only achieves a leap in core performance but also introduces new expansion interfaces, broadening its application boundaries and giving your projects more flexibility and scalability.

PCIe 3.0 x1 Interface (FPC 16-Pin)¶

Supports high-speed peripheral expansion, with a pinout compatible with the Raspberry Pi's PCIe FPC connector.

🚀Recommended Expansion Boards:

• M.2 M-Key Expansion Board (DFR1250): Connect an NVMe SSD to expand storage space, or an AI accelerator card for a massive boost in computing.
• 51W PoE Expansion Board (DFR1248): Complies with the IEEE 802.3bt standard, providing high-power delivery and Gigabit network transmission over a single Ethernet cable.

Power Management Interface (MX1.25-10Pin)¶

For connecting an power management system board.

🚀Recommended Expansion Board:

• 18650 UPS Expansion Board (DFR1247), to enable functions like automatic switching to backup power upon mains failure, charge management, and battery level monitoring.

RTC Battery Holder (1.25mm 2-Pin)¶

Connect a 3V CR2032 or similar coin cell battery with leads to ensure the system time is not lost after power down, improving log accuracy and system reliability.

The RTC battery comes with the board.

9. New DIP Switch¶

To make deployment and debugging more efficient, the LattePanda IOTA includes an onboard two-position DIP switch, allowing you to configure the following functions without entering the BIOS:

Migration Recommendations & Steps¶

1. Review Requirements & Confirm Objectives
2. Clarify migration needs: performance (e.g., 4K/multi-display/high-speed storage), system (is Win11 mandatory?), expansion scenarios (wired/wireless/cellular), power/thermal constraints, security/stability, interface quantity, etc.
3. Compile a list of all hardware/software resources used in the current project (custom peripherals, existing modules and enclosures, special firmware, scripts, etc.).
4. Hardware Compatibility & Electrical Adaptation Check
5. Power Supply is Key: IOTA's recommended power input is 12V. If your previous setup used 5V, you must replace the power adapter/conversion interface to meet IOTA's requirements.
6. Thermal Adaptation: IOTA generates significantly more heat. You must upgrade to a recommended heatsink or optimize the passive cooling structure.
7. Dimensions & Interface Verification: Internal interfaces like GPIO headers and FPC connector pinouts have some changes. Verify if existing enclosures, structural parts, and cables are compatible, and be prepared to replace/customize cables, adapter boards, etc.
8. Peripheral & Display Solution Adaptation
9. Display Interface Upgrade: Users of the original MIPI display must switch to the official eDP display; the interface and mounting methods will need to be changed.
10. Wi-Fi Antennas: If you require high-performance wireless routing (Wi-Fi 6/7), you should plan for dual antenna holes and ensure a proper layout where the signal is not obstructed by a metal enclosure.
11. Test compatibility of external expansion boards, PCIe cards, wireless/cellular modules, and USB devices in advance, paying close attention to any modules with size or power supply issues.
12. OS and Co-processor Firmware Migration
13. It is recommended to use the official Windows 11 image, but you can also install Ubuntu 22.04+/24.04 LTS.
14. Co-processor: The co-processor is now the RP2040 (3.3V). Your original Arduino code for the ATmega32U4 (5V) needs to be adapted and ported (focus on library support, I/O level compatibility, differences in port manipulation, timing/interrupts, etc.).
15. Check the communication method, I/O level, and power supply between the original MCU and its sensors/peripherals. Be cautious and use level-shifting modules where necessary.
16. Interface Function / Expansion Board Testing
17. Verify New Features: Test new interfaces like PCIe, UPS, PoE, and the RTC battery holder one by one to ensure they function as expected.
18. Check if existing expansion boards and HAT modules can be used directly or if they require driver updates or pin adaptations.
19. Test the interplay between the DIP switch and BIOS settings to confirm that functions like auto-power-on and independent co-processor power are enabled as needed.
20. Full Assembly & Load Testing
21. Assemble the new hardware according to the planned structure.
22. Perform no-load and full-load tests upon power-up, paying close attention to power consumption, temperature rise, and noise to identify any shortcomings early.
23. Check the status of onboard LEDs, fans, and communication modules to troubleshoot potential compatibility issues one by one.
