Hardware
The hardware specification is categorized into four parts. It discuses the interfacing of the module and its
corresponding functions and diagrams. It also covers the electrical and mechanical parameters that include the
tabular data of the functionalities and standard values of the RAK11200 WisBlock WiFi Module.

WARNING
Different from other ESP32 boards, the RAK11200 needs to be put manually into download mode. If
you do not force the RAK11200 into download mode, you cannot upload your sketch from Arduino IDE
(or PlatformIO) to the board.
To force the RAK11200 into download mode, you need to connect the pin BOOT0 on the WisBlock
Base RAK5005-O to GND and push the reset button.
The BOOT0 pin is on the J10 pin header, the GND pin is next to it.

Interfaces
UART Interface
The RAK11200 module provides two UART interfaces: UART0 and UART1. The UART0 can be used for firmware
upgrades or to access console output through the WisBlock baseboard USB interface. The UART1 is the main
communication interface with WisIO or WisSensor modules.
