Banana Pi BPI-F2S is the first board with Banana Pi team and SunPlus, this is a industrial-grade board. use Plus1(sp7021) design. this is a industrial-grade board.




SunPlus sp7021 is a revolutionary SoC that has the power of a Linux-grade chip and the integration simplicity of a with ARM Cortex-A7 Quad core,ARM926 real-time core,8051 low-power core

Conceived by Sunplus Technology in collaboration with Tibbo Technology, PLUS1 takes all the sophisticated elements typically found in modern industrial-grade embedded Linux chips, adds a plethora of features targeting IoT and industrial control applications, and delivers the resulting design in a simple microcontroller-like package that needs few external components, simplifies the schematic diagram, and reduces the PCB complexity.

SP7021 is a SoC solution of industrial control. It meets customers’full demand on function but with low cost so that will improve customers’ competitiveness in the market. SP7021 provides rich GPIOs, storage and USB interface. And it provides MIPI CSI interface for video input and HDMI interface for video output. It also provides FPGA interface for function extension. SP7021 also has 4 Ethernet ports providing customers a high competitive solution.

Ethernet - realtime capable, e.g. support EtherCAP, ProfiNET, EtherNET/IP, IEEE 1588? PTP support on the MAC's?


The MAC's - are they hard or soft on the Real Time side (if they even support this)


I don't see bus support for standard buses like SAE J1939, CANOPEN, DeviceNet - at least not declared?


Any support for Housing/Cases that support DIN mounting?


UART support - I don't see defined UART's, so does one have to bit-bang this?


Would be curious to know how/why this is considered Industrial?


Personally - I don't even see this as being safe for Robotics even, much less anything that needs real-time support on the interfaces.
