Raspberry Pi GPIO UART HAT / Shield V1.0

This is RS232 expansion HAT designed for Raspberry Pi 3B / 2B / B +   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. The HATs design is based on the old Raspberry Pi B serial expansion board.

This GPIO UART shield comes with Two independent SPI extended interface which is  I2C extended interface and RS232 standard serial port which can be directly connected to the PC etc. Additionally, you will get the onboard IR receiver for remote control access.
