Serial Expansion HAT for Raspberry Pi I2C Interface External Expansion 2-ch UART 8 GPIOs

Overview There is only 1 ch UART port on the original Raspberry Pi once it is used for terminal debugging no more other serial device is allowed What a poor situation Now you have 2 ch extra UART plus 8 programmable GPIOs just bring this Serial Expansion HAT Features Standard Raspberry Pi 40PIN GPIO extension header supports Raspberry Pi series boardsOnboard SC16IS752 expands 2 ch UART and 8 programmable GPIO through I2C no extra pin requiredIt is stackable up to 16 this modules by setting the address jumper that means up to 32 ch UARTOnboard multi LEDs for indicating the UART working statusReserved I2C control pins allows to work with other control boardsComes with development resources and manual examples in C and python Documents User ManualSchematicDatasheetsDemo CodesSpecifications Operating voltage 3 3VExpansion chip SC16IS752Control interface I2CDimension 65mm x 30mmMounting hole size 3 0mmPackage Included Raspberry Pi in the photos is NOT included Serial Expansion HAT x1RPi screws pack 2pcs x1PH2 0 6PIN wire x2
