Product Specification
Marchio: Waveshare
Nome modello: 2-Channel Isolated RS485 Expansion HAT
Modello CPU: MediaTek MT8125
Tecnologia di connettività: GPIO
Componenti inclusi: 2-CH RS485 HAT x1, 2 x 20 pin femmina pinheader x1, RPi screws pack (2 pezzi) x1
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards. Adopts SC16IS752+SP3485 dual chip combination, converts SPI to RS485, data rate up to 921600bps.
- Allows transceiving data manually or automatically, configured by DIP switch. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, llgthningproof & anti-electrostatic.
- Onboard auto-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
- Onboard LEDs for indicating the power and transceiver status. Breakout SPI control pins, for connecting with host control boards like Arduino.
- It is easy to control the 2-channel RS485 for auto transceiving via SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
