The PandaByte MAX485 TTL to RS485 Converter is a compact and reliable communication module designed to interface microcontrollers with RS485-based industrial and environmental sensors such as NPK soil sensors, wind speed sensors, energy meters, and other MODBUS/RS485 devices.
This module supports direct 5V power from microcontrollers (ESP32, Arduino, STM32, etc.) while also allowing 12V input via a DC barrel jack to power external RS485 sensors—eliminating the need for additional power modules. It is engineered for quick installation, minimal wiring, and stable long-distance communication.
