40 Below Labs
Firmware Engineering

40 Below labs specializes in all stages of firmware development with a focus in IoT


40 Below Labs was started in January of 2022 by myself, James Drewelow. Currently the company is just me, but I have future plans of expanding the company to offer services across more engineering disciplines and eventually work on our own product development.
