#### **Flashing Procedure**
1. The programmer pins must be exposed via male headers at a 2.54mm pitch
2. **Pin Order:** Ensure the pins are arranged in this specific sequence:
1. DTR
2. RX
3. TX
4. 3.3V
5. RTS
6. GND
3. Insert the programmer into the flashing female port of the board, matching the pin names **except for TX and RX**, which are typically swapped.
4. Tilt the programmer at an angle to ensure a solid electrical connection with the port.

5. Open the downloaded **Espressif Flash Download Tool **(Flashing Tool -> flash\_download\_tool\_3.9.4).
6. Upon opening the software, select the following settings:
- **Chip Type:** ESP32-C3
- **WorkMode:** Develop (for single board) or Factory (for multiple boards)
- **LoadMode:** UART

7. Set the file paths at the following addresses:| **File Name** | **Memory Address (Offset)** |
| `bootloader_v2.bin` | 0x0000 |
| `partitions_v2.bin` | 0x8000 |
| `boot_app0_v2.bin` | 0xe000 |
| `AlphaX_BASE_x.x.x.bin` | 0x10000 |
The files can be located at: Flashing Tool -> Firmware -> (select device model eg: Alpha1)
PLEASE USE THE LATEST FILES PROVIDED IN THE ATTACHED FILE ABOVE
8. Configure the **SPI Flash Config** section as follows:
- **SPI SPEED:** 80MHz
- **SPI MODE:** DIO
- **Baud Rate:** 921600
9. The flashing process:
- For Single Boards:
- Select the appropriate **COM port**
- Click **"START"** to begin.
- Monitor the progress bar as the upload proceeds.
- For Multiple Boards (Factory Mode)
- Uncheck **"LockSettings"** to modify configurations.
- Assign the correct **COM port** for each attached programmer.
- Re-check **"LockSettings"** to secure the configuration.
- Click **"START ALL"** to flash all boards simultaneously.
NOTE: It is recommended to ERASE the board first before re-flashing it. This can be done by pressing ERASE in the flashing tool before flashing.

#### **Verification**
Once the upload is complete, look for the following indicator on the board:
- The **blue, green, and yellow LEDs** will flash **twice** to signify a successful firmware upload
- The **blue** led will start blinking continuously indicating that device is ready to be setup and configured
