Product information "Elecrow UART TTL to RS485 2-way converter, lightning and anti-interference protection, half-duplex, 3.3-5.0V"
This module enables the TTL interface of the microcontroller to be transferred to the RS485 module. It is commonly used for industrial automation. This module adds lightning protection design and anti-interference design. When we use it in the field and perform long-distance transmission, we can connect the GND terminal of the module to the ground to achieve lightning protection and anti-interference.
It uses a standard design with a pitch of 2.54 mm. If you want to make the second development, it will be more convenient. It has a 120 ohm terminating resistor that can R0 when short-circuited, it is recommended that users be short-circuited in long-distance transmissions. It supports communication between multiple microcontrollers and allows up to 128 devices on the bus. It can be hot-swapped to avoid signal interference. A large copper area has been implemented, the effect is very good.
