How to check the firmware version on your SpeedyEFI
Step 1. Download and install and open the Arduino software from Arduino.cc (it’s free)
Step 2. In the Tools dropdown menu, change the COM port to whichever one your Speedy showed up as. (usually it’s COM4-10, COM1 is the default for Windows, don’t worry about COM1)
Step 3. In the Tools dropdown menu, open the Serial Monitor. You’ll see a blank bar across the top, with a “SEND” button next to it. Type a capital S, and click send. In the lower box you should see it display something to the effect of “Speeduino082018”. The first two numbers are the month code, and the last two or four are the year.
You may need to change the BAUD rate in the bottom right
hand corner of the window to 115200.
