This page covers any general information for the Fly-407ZG board.
It is currently available through AliExpress
The board name in board.txt is fly_f407zg.
The Fly-407ZG is supplied with 2 heatsinks. They should be installed as per the image below.
The jumpers should be installed as below. “Common Interpolation” should be used for standalone drivers. “SPI mode Interpolation” is not a currently supported configuration as this port does not support SPI communication to drivers. “UART mode Interpolation” should be used when using smart drivers (i.e. TMC2208, TMC2209, TMC2225 and TMC2226)
The board can handle an input voltage up to 32v.
The board that you will receive doesn’t have any firmware installed so when plugged into a computer, the board will show as an unidentified device. Follow the ESP8266 WiFi instructions, ESP32 WiFi instructions or the SBC instructions for what to do next.
Some boards shipped are missing the bootloader.
