@world101 My m5stack grey is 2018.3, but i don't know if with the IP5306_I2C chip.

@salty_good Yes. I use Arduino IDE.

@ajb2k3 I using the one that cannot be found

@ajb2k3 But I can find IP5306 on another board by same program.

I want to get the battery charge status, but can't find IP5306 I2C address, only find the MPU9250 I2C address (0x68)
