Technical overview
- The module converts a serial UART TTL interface into an Ethernet signal.
- It is designed as a stable converter with high speed and low power consumption.
- Interfaces: UART on one side, Ethernet on the other.
- Related modules in the same product family include 2-CH UART TO ETH, RS485 TO ETH, RS485 TO ETH (B), and RS232/485 TO ETH.
- The vendor provides resources such as user manual, code, PCB library dimensions, and software for this module.
- IPv6 is not supported, according to the FAQ.
- For RS485 operation, an additional conversion circuit following the RS485 (3.3 V) pattern must be added; the module already has a reserved pin for RS485 enable.
- Category: Modules, subcategory Ethernet; brand: Waveshare.
Notes and version constraints
- Exact electrical limits (voltage, current, baud rates) are not stated in the source – confirm before integration.
- RS485 usage requires extra circuitry; without it, operation is not possible.
- Version-specific steps or firmware versions are missing from the source; human confirmation needed when updating.
- The IPv6 question was answered negatively; if IPv6 is required, a different module must be selected.
