DESK OF LADYADA - STEMMA Sunday + Low Power Evening - The Great Search: Ultra low quiescent 3.3V reg
Every Sunday we work on a new STEMMA QT board - this week we made one for the MCP9601 - an I2C capable thermocouple sensor. This is one of the only I2C thermocouple AFE's we've seen, and we've already got a library for the earlier MCP9600. (The MCP9601 adds open-thermocouple detection!) We also worked on the Feather M4 CAN - with Arduino and CircuitPython support nearly wrapped, its time to finish the hardware. We have a few changes we made to reduce the power draw and got down to 250uA in sleep mode....but could we go lower? The Great Search: Ultra low quiescent 3.3V regulator…
