PI-CPUF407

PI-CPUF407 is a module with STM32F407 processor, Fast Ethernet and Wi-Fi communication interface, SD card slot, two USB 2.0 peripheral interfaces (1x Full Speed and 1x High speed) and GPIO expansion connector with digital and analog inputs and outputs. The advantage is low power consumption, which also allows battery operation. The module has a small Rasberry PI format size with similarly placed connectors and mounting holes, so it fits into most Rasberry PI boxes. Also, the expansion GPIO connector has a similar wiring so that expansion HAT modules can also be used.

PI-CPUF407 is available also without Wi-Fi, Ethernet  and/or USB.

A sample application is available to speed up the development of the desired application.

The sample application contains:
    • Bootloader for application update over terminal
    • OS FreeRTOS
    • TCP/IP stack lwIP
    • DHCP client
    • NTP client
    • Command terminal via serial line and telnet (commands similar to OS Linux)
    • FatFs for reading MicroSD card files and USB drives

Block diagram of PI-CPUF407:

The PI-CPUF407 includes an expansion connector with GPIO, which can be used to connect additional modules and thus expand the required interfaces. The connector wiring is as follows:

* These pins do not have hardware support for SPI, but can be emulated in software
