ESP32-WROVER-E ESP32-DEVKITC Core Board for Arduino

ESP32 WROVER E CH340 ESP32 DEVKITC Core Board for Arduino The module has a gold pin connector (2.54 mm pitch) and a micro USB connector. For additional communication, we use integrated buttons and LEDs on the board.

CH340 is a USB bus conversion chip, it can realize USB to UART interface or USB to printer interface.
In serial UART mode, CH340 provides a common MODEM liaison signal, used to expand the UART interface of
the computer or upgrade the common serial device to a USB bus directly. For more information on USB conversion to
printer interface please refer to the manual CH340DS2.

Features

• Full-speed USB device interface, compatible with USB V2.0.
• Emulate standard UART interface, used to upgrade the serial peripherals, or expand UART interface via USB bus.
• Original serial applications are totally compatible, without any modification in the Windows operation system.
• Hardware full duplex serial UART interface, built-in transmit-receive buffer, supports communication baud rate varies from 50bps to 2Mbps.
• Supports common MODEM liaison signal RTS, DTR, DCD, RI, DSR, and CTS.
  Through external level conversion chip provide further RS232, RS485, RS422 interface, etc
• CH340R supports IrDA criterion SIR infrared communication, supports baud rate varies from 2400bps to 115200bps.
• Software compatible with CH341, use the driver of CH341 directly.
• Support 5V and 3.3V power supply even 3V.
• CH340C, CH340E, and CH340B have built-in crystal, no external crystal, CH340B also integrates EEPROM is used to configure the serial number, etc.
• SOP-16 and SSOP-20 and MSOP-10 lead-free RoHS compliant package.
