comma serial

You messed up. You messed up your BRAND NEW comma 3X. You are sad. You don’t even see anything on the screen. If only you knew what was going on…

Now, with a comma serial, you can know! Connect your comma serial to your device, the adapter to the wall, and the USB to a computer. You have solid power for your device + access to the lowest level serial console over a simple USB connection.

Buy your comma serial before you are in this situation, that way you can say, “don’t worry, I bought a comma serial”.
