I'm designing a custom pcb with a BMP280 onboard controlled by an ATMEGA-4809. I read the datasheet and I understood that I've to power my sensor with 1.8 V and 4.2 uA, so do you know any voltage regulator that has an output like this?
Thanks a lot, good luck,
Solved! Go to Solution.
There was reference schematic of applicaiton board 3.0 https://www.bosch-sensortec.com/media/boschsensortec/downloads/software_tools/application_board_3_0/..., it supplied 1.8V to MEMS sensor.
How much voltage does your MCU supply? If it is higher than 1.8V, then you need to add Bidirectional Voltage-Level Translator between MCU pins and sensor pins.
