Description

We need an I2C buffer to isolate power domains on the spacecraft! Ex. between OBC and ADCS, between OBC and EPS, etc. This buffer should be open drain to be compatible with I2C, support same-to-same voltage conversion (i.e. 3V3 to 3V3), and be automotive rated.

Tasks

• [x] Learn about I2C
• [ ] Find buffer
• [ ] Design an Altium schematic block for this buffer that can be reused

Notes

Space for research notes, open questions, progress logs

Requirements

• Need to be able to solder it yourself
• automotive rated
• same to same voltage
