Product Description

This development card is equipped with the ESP32-WROOM-32D module from Espressive. It is a CMS module (mounted on the surface) integrating an ESP32 chip, the components necessary for its operation, all the RF filtering, as well as a PCB antenna. The set is mounted in the form of modules directly welded on the development card.

Unlike the classic ESP32-Wroom version (which you can find here), the module is welded on the map so that the antenna is outside the card. Allowing better RF performance.

This card is ideal for IoT, home automation and network bridge (bridge) application developments. Its low consumption as well as its compatibility with the Arduino environment make this card a “must-have” for any hacker and hacker.

802.11 b/g/n and Bluetooth 4.2 and ble.

Main component

Key Component	Description
On-board module (ESP32-S2-MINI-1 or ESP32-S2-MINI-1U in figures above)	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. For more information, please refer to Ordering Information.
Pin Headers	All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. Users can program ESP32-S2FH4 chip to enable multiple functions such as SPI, I2S, UART, I2C, touch sensors, PWM etc. For details, please see Header Block.
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.
Reset Button	Reset button.
Micro-USB Port	USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2FH4 chip.
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.
External Antenna Connector	On ESP32-S2-MINI-2U and ESP32-S2-MINI-1U module only. For connector dimensions, please refer to Section External Antenna Connector Dimensions in module datasheet.
