Project description

Summary This project is a compact sub-control board for an autonomous wheeled vehicle that uses a Seeed XIAO SAMD21, a WIZnet W5500 Ethernet module, and a 74LS04N inverter to convert wired network commands into an inverted SBUS output. The W5500 is the TCP/IP input stage, the XIAO SAMD21 decodes command data, and the 74LS04N converts the UART signal into the inverted logic format expected by SBUS-compatible RC or motor-control receivers. What the Project Does This board is not a general-purpose main controller. It is a dedicated Ethernet-to-SBUS gateway. The repository identifies the board…
