2-Channel Isolated RS485 Expansion HAT for Raspberry Pi
[My Features]Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboardsUsing SC16IS752 and SP3485 dual-chip combination scheme, SPI can be converted to RS485, and the communication rate is up to 921600bpsSupport manual or automatic sending and receiving of data, which can be set by dial switchThe onboard TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient spike voltage in the circuit, and is anti-lightning and anti-staticThe onboard self-recovery fuse and protection diode can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistanceOnboard power supply and serial port transceiver indicator light, easy to check the module power and communication statusLeads out the SPI control interface for easy access to the main control boardProvide complete supporting information manuals (C and python sample programs and user manuals, etc.)[My parameters]Serial port expansion chip: SC16IS752RS485 transceiver: SP3485Communication interface: SPICommunication rate: 300 ~ 921600 bpsWorking voltage: 3.3V / 5VProduct size: 65mm × 56.5mmThrough hole diameter: 3.0mm
