Hi,
I bought the MLX90640 breakout board from you ((#PI279072) and tried it out with an M5stack and the
software https://github.com/DIY-projects/M5Stack-MLX90640-Thermal-Camera as well as the Sparkfun
examples linked on the product page and I only get no acks. The Sparkfun example gives the following
output:
