DescriptionThe RS485 conversion terminal is a compact BAVG to Socket adapter for RS485 line construction in M5Stack hardware projects. It combines a 2.54-2P terminal with a DC power input interface and converts the wiring side to a 3.96-4P terminal, making it easier to connect devices that use the 3.96-4P interface.This RS485 conversion terminal is useful when a project needs both signal wiring and external DC power input in a small adapter. The DC input interface supports 9-24V and lets users power compatible RS485 installations with common DC adapters while keeping the terminal connection organized.Because the RS485 conversion terminal includes the conversion terminal, terminal blocks, a plug-in resistor, and an I/O sticker, it is suitable for quick bench wiring, controller integration, and compact RS485 device installation work.Features RS485 line construction: the RS485 conversion terminal helps route RS485 wiring through a compact adapter format. Terminal conversion: converts a 2.54-2P terminal plus DC input layout to a 3.96-4P terminal interface. DC power input: integrated DC input interface supports 9-24V external power supply. M5 hardware compatibility: suitable for devices in the M5 hardware ecosystem that use a 3.96-4P interface. Included resistor and sticker: supplied with a 120Ω plug-in resistor and I/O sticker for organized installation. Small adapter size: 17 x 30 x 10mm body fits compact wiring panels and controller setups.
