AIO_V1.4 User Manual
Function Switch
The PCB features a function switch on the top, allowing users to toggle between three module functions. An LED below the switch indicates the current function:
- Red light: 2.4Ghz transceiver module
- Green light: WIFI module
- Blue light: CC1101 module
The switch on the back of the PCB controls the built-in gain circuit of the CC1101 module. In the RX position, the CC1101 module's receiving function is amplified. In the TX position, the transmitting function is amplified. When in the RX position, the module can receive, but the TX function does not receive gain amplification.
Caution: Do not plug or unplug the module while it is powered on, as this may damage the module power supply function.

- Set the toggle switch on the front of the PCB to the middle position.
- Connect the PCB to your computer via a USB-C cable. The front LED should turn green.
- Click the 'CONNECT' button on the web page.
- In the prompt window, select the 'esp32-s2' chip.
- Click the image to add the downloaded file to the corresponding address. The following files are typically used:
- esp32_marauder.ino.bootloader.bin
- esp32_marauder.ino.partitions.bin
- boot_app0.bin
- esp32_marauder_v0_13_9_20240227_flipper.bin
- Click the 'PROGRAM' button to start the download. A confirmation window will appear; click 'CONTINUE'.
- Upon reaching 100% progress, the download is complete. If an error occurs or the progress is interrupted, verify the module's connection and the USB interface connection to the computer. Reconnect and attempt burning again if necessary.
Troubleshooting Note: An error message like 'TypeError: Cannot read properties of null (reading 'getWriter')' may indicate a connection issue. To run the new firmware, reset the device after successful flashing.
