Hardware Revisions
NOTICE - Beginning in August 2020, production began transitioning from the Compute Module 3 Lite (CM3L) to the Compute Module 3+ Lite (CM3+L). Use the command cat /proc/device-tree/model
to verify the precise hardware. If you are using an older operating system you many need to update the Raspberry Pi Firmware for it to boot.
