Insert a SD card to expand storage space, such as storing large data content such as font libraries, images, audio files, etc. |
|
RGB tricolor light |
Contains LEDs of three colors: red, green, blue. It has a built-in control IC and only needs one IO port to control. It can be used for LED testing and status indication. |
|
UART |
1.25mm4P socket. It can be used for serial port debugging, downloading, and communication. An external USB to serial port module is required. |
|
Battery interface |
1.25mm 2P socket. Used to connect to a 3.7V polymer lithium battery, charge the battery through the battery management circuit, and can also be used for battery power supply. Note the positive and negative terminals of the interface. |
|
BOOT key |
Used to enter the download mode or key test. Press and this key to power up, then release to enter the download mode, or after powering up, press and hold this key, then press the RESET key, release the RES key and then release this key, you can also enter the download mode. When you don't need to enter the download mode, this key can be used as a normal key |
|
TYPE-C interface |
It is used for module power supply and program download, debugging. This interface is connected to the internal USB bus of ESP32-S3, which can generate a USB serial port. Note: win10 and above systems support USB virtual serial port function. If you use this interface on other versions of the system, you need to solve the problem USB virtual serial port not working by yourself. |
|
RESET key |
For ESP32-S3 main control and LCD reset, press to reset low level. |
|
Expansion pin |
1.25mm 4P socket. Two pins are GPIO45 and GPIO46. It can be used to connect other peripherals. |
|
Speaker interface |
1.25mm P socket. Used to connect the speaker to play audio. Used to connect the speaker to play audio (maximum support 1.5W (8Ω) or 2W4Ω) speaker. |
|
I2C peripheral interface |
1.25mm 4P connector. Used for connecting external IIC communication devices. This IIC interface is shared with capacitive touchscreens. Can also be used for general I/O. |
