Waveshare TTL to RS485 (C) Galvanic Isolated Converter – Half-Duplex Communication Module TYPE-C-SMD_TYPE-C-31-M-16 The Solid State Relay (SSR)

The Solid State Relay (SSR) offers many advantages over the classic mechanical relay: it has a longer life

2 ohm Color Code Brown

leading to a cheaper design and smaller pc-board footprints

TTP224N-BSB is a widely used 4-channel capacitive touch chip with up to 4 touch input ports and 4 direct output ports

as with most of the MOSFETs

Waveshare TTL to RS485 (C) Galvanic Isolated Converter – Half-Duplex Communication Module TYPE-C-SMD_TYPE-C-31-M-16 The Solid State Relay (SSR)The Waveshare TTL to RS485 (C) is a compact, high reliability module that converts TTL level signals (3. 3V or 5V) to RS485 differential signals with full galvanic isolation. Designed for industrial and embedded applications, it ensures robust communication over long distances while protecting connected devices from electrical surges and interference.
