Hi, the operating voltage of C1001 is 5V DC.

This is because the RF circuitry on the board needs 5V to work at optimal operating conditions.
So the 3.3V supply may not be enough.

You can use Mind+ to re-initialise it through the steps on the official K10 website.
And burn the English version of the factory programme.

You can understand that the BLE Sensor Beacon is a very simple MCU dev board.
Its only function is to receive data from digital/analogue/I2C sensors and transmit it out via Bluetooth BLE.
Unfortunately it doesn't support tag reading.

Possibly you looked at the guided tutorials for the UNIHIKER M10.
The K10 is an ESP32 based MCU dev board. so it will appear as a COM port on your PC when connected via USB.
The default is the ArduinoC firmware, you need to flash micropython firmware first if you want to program with Thonny.

The FireBeetle ESP32 uses the CH340 as the USB-TTL converter chip, can you confirm that you have installed the driver for this chip on your computer?

Windows: https://www.wch-ic.com/downloads/CH341SER_EXE.html

MacOS: https://www.wch-ic.com/downloads/CH341SER_MAC_ZIP.html

Linux: https://www.wch-ic.com/downloads/CH341SER_LINUX_ZIP.html

However, the CH340 driver is built-in in most modern Linux distributions, so if you have Linux and don't have a CH340 driver, it's more advisable to upgrade the Linux kernel rather than installing the driver manually.

We are very sorry, but we have no plans to do so at this time.
The silkscreen on our PCBs often indicates the name of the product. You can search for that product on the official website by the product name.

This sensor doesn't output actual data, it just outputs a high level signal when it detects a liquid, so it doesn't have a resolution parameter.

The SGP40 library released by DFRobot has a readRawdata() function that directly outputs VOC raw data.

What kind of ultrasonic sensor are you using? Trig-echo type like SR-04?

DFRobot got example code for this type of sensor:

As of today, platform io has not been adapted to any third-party ESP32-C6 dev boards. only boards from the ESP manufacturer espressif can be adapted.

It looks like only two esp32-c6 from espressif(which is the manufacturer of ESP32 ) could support platform io.

You can try to use UNO's 3.3V to power it and test it again. If the sensor can work properly with UNO's 3.3V, then it is not a power supply problem. DFRobot's wiki also shows that the sensor can work at 3~5V.

Next you need to check whether the sensor is connected to GP20 and GP21, because PR2040 has two I2C buses, and the wire corresponds to I2C0.

Can you upload an I2C scanner to verify this? If the I2C scanner does confirm that the silkscreen is in the wrong direction, you can find the seller for after-sales service.

You could find the I2C scanner in this URL:

This is a product that has not yet been released to the market. The code on GitHub is only used for internal testing by DFRobot R&D personnel.

If you are asking about the through holes in the red box below, these are GND through holes because the current through the module can be high, so multiple GND through holes will reduce EMI.

Yes it could convert UART data frame to the CAN data frame.

The UART interface accept the AT command, you could refer to the wiki tutorial:

Hello,

This extension also works with older versions of Maqueen V3.

EN can be seen as an input pin.
EN controls a MOSFET, and the 5V output of the Solar power manager will only be enabled when the EN input is high. If your ALARM camera can output 5V and 0V, you can connect the GND of the ALARM camera to the GND of the blue pin of the Solar Power Manager, and then connect the ALARM signal output line to EN.

You can directly email DFRobot technical support for the register list, and they will provide it to you. The product manager of SEN0460 has not made it public on the wiki.
