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 a perfect choice for fields like industrial automation.
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards. Adopts SC16IS752+SP3232 dual chip combination, converts SPI to RS232, data rate up to 921600bps
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic. Onboard LEDs for indicating the power and transceiver status
Breakout SPI control pins, for connecting with host control boards like Comes.
