Hi Antanas, this confirguration is feasible. However, your configuration requires modifying the BIOS. Have you started the schematic design yet? You can send techsupport@lattepanda.com the design files after completing the design for our review.

If you want to use the PCIE slot, you will need to fidn a 12V power supply.

Are you using LattePanda 3 Delta? which OS  did you use? you can install the offcial windows image to rule out the driver issue.

Pls contact techsupport@lattepanda.com for A/S services.

Hi, LattePanda Mu doesn't have onboard Arduino. May we know what peripherals you need to use?

here is the DOCS of LattePanda Mu for your reference.

Hi, the cable below is compatible with LattePanda 2 Alpha, and LattePanda 3 Delta 864.

With the DC 5.5x2.1mm Power Cable, LattePanda can be powered by a common 12V DC power supply or a 12V battery pack easily.

It sounds like you've already tried some effective troubleshooting steps. If you're using the Arduino IDE, make sure that you have selected the correct board and COM port. Additionally, check the "Tools" menu for any specific settings related to the LattePanda configuration.

LattePanda V1 uses onboard wireless module, this issue seems to be related to the abnormal power supply of the network card on the board.
If possible, you can measure the voltage supply and signal of this module to see if it works properly.

Your current setup, where you are powering the PN532 with a 3.3V supply while sharing the ground with the LattePanda, raises some important considerations regarding voltage levels. The LattePanda’s I2C operates at 1.8V, and connecting a 3.3V device directly to it without proper level shifting can potentially lead to issues.

The I2C signals from the LattePanda are at 1.8V, while the PN532 operates at 3.3V. Directly connecting the I2C lines (SDA and SCL) from the LattePanda to the PN532 could expose the LattePanda’s I2C pins to higher voltage levels, which may damage the I2C interface of your LattePanda.

It could potentially be related to a few factors.

1. Connection: Ensure that all connections between the display and the LattePanda are secure. 

2. Cable Integrity: Check the ribbon cables for any signs of wear or damage. 

May we know what kind of the vibration is? Any special application?

Please feel free to reach out if you need further assistance or have additional questions.

the M.2 b key on LattePanda 3 Delta is for 4G/5G modules. We suggest you contact techsupport@lattepanda.com for repair service.

Hi Robert,

Sigma: which Sigma model did you purchase? LattePanda Sigma doesn't have eMMC, you need to add an SSD with operating system to LattePanda Sigma.

Mu Full evaluation board: could you pls take a video of your configuration and operation? we will help check it out.

thanks.

Has it run successfully with MU? The sample looks very good.

thanks for sharing. Looking forward to your update.

Hi Null Panda,

may we know why you need those LPDDR5 chips? due to physical design of LattePanda Sigma, Sigma maximum supports 32GB RAM.

Upon starting the board, quickly access the BIOS and turn off the watchdog feature, then save your changes and exit. Should you be pressed for time and unable to tolerate any delay, consider employing a programmer to reflash the BIOS and reset it to factory defaults.

Hi, you could try reflashing the BIOS using a programmer.

Currently, we do not have plans to release an enclosure for the full carrier board. We suggest using a standard ITX case or keeping an eye on designs from our community users.

We recommend that you visit the following link: https://docs.lattepanda.com/content/alpha_edition/powering/, which offers a variety of power supply options for the Alpha. You can choose according to your needs. Please be aware that the 5V3A power supply you mentioned is insufficient.

Apologies for the inconvenience this has caused you. Could you please inform us of the model and specifications of the device that can be recognized? Are you also unable to detect a standard mouse and keyboard when connected? Is the issue confined solely to the middle USB-A port? Are the other two USB ports functioning correctly?

If possible, we would appreciate it if you could provide a short video demonstrating the operational device and the USB device that is not working to techsupport@lattepanda.com. Thank you for your cooperation.
