All E-Stim System 2B are shipped from our workshops with the most up to date versions of firmware available at the time of shipping, but we also have Beta firmware for you to try if you want to become cutting edge, and if you really want to live on the sharp edge, then why not consider joining our developers forum at and get access to the very latest beta versions.

If you have an older 2B (before 2.104) then you might need to update the Bootloader. the Bootloader is the small program that sits inside a 2B that allows you to download the Firmware onto the 2B. We don't often change the bootloader so it is unlikely you will need the code unless you are updating a very old 2B. Instructions on how to install the Bootloader can be found here.
