It is always possible to know which firmware version is running. The BITalino API can tell that. If you are communicating directly with the BITalino device through the BITalino protocol, the device sends the firmware version string as a reply to the command byte 0x07.
Anyway, you can program your BITalino (r)evolution device with firmware v5.1. On the GitHub repository for the firmware (https://github.com/BITalinoWorld/firmwa ... revolution
) you can find instructions on how to program the device.
