Other Parts Discussed in Thread: BQ20Z40-R1 We are a group of students designing a cube-sat in a local space program, for use in future experiments( supposing it works that well).
I am planning to use roughly the suggested schematic in the Bq20z40-R1…
Other Parts Discussed in Thread: BQ20Z40-R1 , BQ29330 Hello, I am trying to interface a bq20z40-r1 gas gauge with an arduino and I am having difficulties interfacing through i2c. I am unable to find a default address of the chip in the manual and am wondering…
Other Parts Discussed in Thread: BQ20Z40 We are using the bq20z40 on a design and have some questions. In a nutshell, we need the device to go to sleep but cannot make the SMBus lines low without a board change. So, we are looking for alternative methods…
Thank you for the information.
