Frequently Asked Questions

How do I program the WeAct S3 Mini board using the Arduino IDE?

First, install the ESP32 board support via the Arduino Boards Manager using the Espressif repository URL. Select 'ESP32S3 Dev Module' as your board. Configure the flash mode to 'QIO', flash size to '4MB', and PSRAM to 'Enabled'. Connect the board via USB-C, select the correct COM port, and upload your sketch. The board uses the standard USB CDC serial protocol for communication.

What is the purpose of the 2MB PSRAM on the ESP32-S3FH4R2 in this board?

The 2MB of pseudo-static RAM (PSRAM) provides additional volatile memory for data-intensive applications. It is useful for buffering images, audio streams, complex data structures, or serving as a heap extension in MicroPython. This allows your IoT application to handle larger datasets or more sophisticated graphics without being constrained by the chip's internal SRAM.

Can I power this board directly from a 3.3V pin, bypassing the USB Type-C port?

No, you should not apply 3.3V directly to the board's 3.3V pin. The onboard voltage regulator is designed to accept 5V input via the USB-C port. For external power, supply 5V to the USB-C connector's VBUS pin or use a regulated 5V source connected to the appropriate test pad, ensuring you do not exceed the regulator's current limits.

How do I enable Bluetooth Low Energy (BLE) advertising in MicroPython on this board?

After flashing the MicroPython firmware for ESP32-S3, use the 'ubluetooth' module. Initialize the BLE object with `ble = bluetooth.BLE()` and then activate it with `ble.active(True)`. Create an advertising payload using `ble.gap_advertise(interval_us, adv_data)` where 'adv_data' is a byte array containing your device name and service UUIDs. Refer to the MicroPython docs for detailed BLE server/client examples.
