# Environmental Data Logger Copilot V2 Example Project
## Description
Overview: BME280 Sensor data -> uSD card
Click on the bubble comments to see copilot design this project! Very impressed copilot routed all the SPI buses accurately for me.
TODO: Just realized that there is no footprint for the SD Card holder, gotta add that
Also, there needs to be a way to program the ATTINY841, Probably over UART?
