Description
This is an STM32F407 based Arduino Mega replacement for PnPduino and Speeduino boards (designed by pazi88). Advantage of this board to Mega is Onboard SD Logging and CANBUS. This can also expand to 8injection/8ignition for custom boards. Current firmware installed is 202402.1 using FTDI (Serial 3 will work in this configuration). SD Card is included but battery is not included due to shipping restrictions. RTC battery holder can accept CR1225, CR1220 or CR1216 coin cell battery – battery is required to keep the date and time.
By default, the SD logging does not show in Tunerstudio when using STM32 as the processor. The speeduino.ini file from 202402.1 firmware\reference should be modified. The easiest way is to install Notepad++ and edit speeduino.ini file, go to line 2007 and change mcu_teensy to mcu_stm32 and save. Reload the ini file on your project and it should enable all the SD logging settings.
