BMS
DIY BMS using ATTINY841-SSU this hardware has a higher balance current, fuse and TVS diode to help with voltage spikes. Most importantly, an external crystal to the micro controller (attiny841) which means the device is more reliable in low voltage situations... show more157 Comments

Environmental Data Logger Copilot V2 Example Project
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?... show more6 Stars
