Description
Description
The converter features a Raspberry Pi 40PIN GPIO extension header and supports Raspberry Pi series boards. It adopts the combination scheme of SC16IS752, SP3485, and SP3232, converting SPI to RS485 & RS232. The integrated resettable fuse and protection diodes ensure stable RS485 current and voltage output, prevent overcurrent and overvoltage, and enhance shock resistance. The onboard TVS (Transient Voltage Suppressor) can effectively suppress surges and transient peak voltages in the circuit, is lightning-proof, and anti-static. It also includes breakout SPI control pins for connection to Arduino and other host control boards.
