The Waveshare TTL to RS485 (C) Galvanic Isolated Converter is a compact TTL-to-RS485 serial converter designed to convert TTL signals into balanced differential RS485 signals for reliable half-duplex communication. It supports 3.3V to 5V TTL signal levels and provides galvanic isolation for both power and digital signals, helping reduce interference and improve communication stability.
The TTL interface supports a transmission distance of less than 10m, while the RS485 interface can achieve a transmission distance of about 1200m (1.2km). For RS485 networks, it supports point-to-multipoint communication with up to 32 nodes, with repeaters recommended when using 16 nodes or more. The converter also features 200W lightningproof and surge-suppress protection, 6KV ESD protection, TVS transient voltage suppression, a self-recovery fuse, and protection diodes for improved circuit safety.
A 120R terminal resistor is provided and can be enabled through soldering. With dimensions of exactly 42.8 × 15.2 × 4.75mm, this galvanically isolated TTL to RS485 converter is well suited for embedded systems, MCU projects, industrial communication, IoT devices, node expansion, and applications requiring longer-distance serial communication.

This product comes with a 1-year manufacturer warranty from the date of purchase, covering manufacturing defects only.
The product shows signs of physical damage, mishandling, exposure to water/moisture, fire, natural calamities, unauthorized repairs, improper storage near heat or direct sunlight, or alteration in any way.
Replaced a failing non-isolated unit—immediate stability. Secure packaging, no loose parts. Website UX was intuitive. Device stays cool during continuous use. Tech team confirmed RoHS compliance when asked. Essential for any serious RS485 project.
Cheaper units failed this one didn’t. Box arrived intact. Website had real-time stock info. Galvanic isolation prevents ground loops effectively. Support team sent test code snippet. Now buying in bulk for fleet deployment.
Tiny but mighty—handles long cable runs flawlessly. Arrived in padded envelope, no damage. Easy to wire with clear silkscreen. Customer support confirmed compatibility before I bought. Works perfectly with Arduino and industrial sensors alike.
Clean waveforms even at 115200 baud. Minimalist packaging but safe. Ordered late Friday—shipped Monday. Product quality matches datasheet specs. Customer service followed up post-purchase. Perfect for precision instrumentation links.
Used outdoors for six months—still perfect. Sealed in moisture-resistant bag. Website checkout had discount code applied automatically. Terminal blocks accept stranded wire easily. No data loss even during thunderstorms. Impressive resilience.
