Board Pinout
The pinout including the schematics of the board are described in detail in the data sheet.
The board has different external interfaces that can be used to connect external hardware:
Extended I/O Interface (EXT)
| Pin | Description |
|---|---|
| 1 | 5V |
| 2 | GND |
| 3 | EXT_IO1 (GPIO10) |
| 4 | EXT_IO2 (GPIO11) |
| 5 | EXT_IO3 (GPIO12) |
| 6 | EXT_IO4 (GPIO13) |
| 7 | EXT_IO5 (GPIO14) |
| 8 | EXT_IO6 (GPIO21) |
RS485 Interface
| Pin | Description |
|---|---|
| 1 | RS485-A |
| 2 | RS485-B |
| 3 | GND |
| 4 | 5V |
Debug Interface (DEBUG)
| Pin | Description |
|---|---|
| 1 | 5V |
| 2 | 3V3 |
| 3 | UART_DEV(0) TxD |
| 4 | UART_DEV(0) RxD |
| 5 | RESET (EN) |
| 6 | BOOT (GPIO0) |
| 7 | GND |
Flashing the Device
Since the ESP32-S3 WT32-SC01 Plus does not have a USB-to-Serial chip, the easiest way to flash it is using the USB Serial/JTAG interface. Just connect the ESP32-S3 WT32-SC01 Plus to your host computer and use the following command:
Usually the make system resets the ESP32-S3 WT32-SC01 Plus before flashing to enable the USB Serial/JTAG controller and to reboot the ESP32-S3 in download mode.
Debugging with the Device
To be able to debug with the board, it must not use the STDIO via the USB OTG interface as it does by default. Instead, the STDIO must use the UART interface. For this purpose, compile and flash the application with the following command:
In order to use the STDIO in a terminal in this case, a debugging tool is available on the market, which is connected to the debug interface of the board.
- Note
- The debugging tool does not mean that it is used as OpenOCD adapter. It simply exposes the UART interface.
