This is a 2-channel isolated RS232 expansion HAT designed for Raspberry Pi, adopts the SC16IS752+SP3232 solution, with embedded protection circuits such as power supply isolation, ADI magnetical isolation, and TVS diode, etc. It is easy to control the 2-channel RS232 via SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
^^Features 1: Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards.
Features 2: Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
^^Features 3: Onboard LEDs for indicating the power and transceiver status. Breakout SPI control pins, for connecting with host control boards like Arduino^^Adopts SC16IS752+SP3232 dual chip combination, converts SPI to RS232, data rate up to 921600bps
UART expansion chip: SC16IS752.
RS232 transceiver: SP3232. ^^How
