Description of Components
key components of the board are
| Key Component | Description |
|---|---|
| On-board module (ESP32-S2-MINI-1 | ESP32-S2-MINI series modules with an on-board PCB antenna or a connector for an external antenna. This series of modules, known for its small size, have a flash and/or a PSRAM integrated in the chip package |
| Pin Headers | pin headers on the board expose all GPIO pins of the ESP32-S2FH4 chip, except for the SPI bus dedicated to flash memory. These pins can be utilized by users to enable various functions, including SPI, I2S, UART, I2C, touch sensors, PWM, and more through programming |
| 3.3 V Power On LED | Turns on when the USB power is connected to the board. |
| USB to UART Bridge | Single USB-UART bridge chip provides transfer rates up to 3 Mbps. |
| Micro-USB Port | USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2FH4 chi |
| Boot Button | Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. |
| RGB LED | Addressable RGB LED, driven by GPIO18. |
| 5 V to 3.3 V LDO | Power regulator that converts a 5 V supply into a 3.3 V output. |
