# 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? ## Project Details - **Owner:** markwuflux - **Created:** 6/27/2023 - **Last Updated:** 9/7/2023 - **Visibility:** Public - **Stars:** 6 - **Forks:** 1 - **Copies:** 4 ## Key Components ### J1 — uSD Socket with SPI Naming Conventions - Manufacturer Part Number: Micro_SD_Card **Pins:** - CD1 / SHIELD - CD2 / SHIELD - CS - GND - GND1 / SHIELD - GND3 / SHIELD - MISO - MOSI - NC - RSV - SCK - VCC ### J3 — [Pin Header 01x04 2.54mm Vertical](https://www.flux.ai/adrian95/pin-header-01x04-254mm-vertical~l97.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] ### U1 — ATTINY841-SSU with SPI Naming Conventions - Datasheet URL: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8495-8-bit-AVR-Microcontrollers-ATtiny441-ATtiny841_Datasheet-Summary.pdf - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: ATTINY841-SSU - Manufacturer Name: Microchip - Part Type: Microcontroller **Pins:** - ~RESET~/PB3 [pin 4] - AREF/PA0 [pin 13] - GND [pin 14] - PA1 [pin 12] - PA2-SS-alt [pin 11] - PA3 [pin 10] - PA4-SCK-default [pin 9] - PA5-MISO-default [pin 8] - PA6-MOSI-default [pin 7] - PA7-SS-default [pin 6] - PB2 [pin 5] - VCC [pin 1] - XTAL1/PB0 [pin 2] - XTAL2/PB1 [pin 3] ### U2 — [BME280](https://www.flux.ai/chaykak2/bme280~vm.md) - Manufacturer Part Number: BME280 - Manufacturer Name: Bosch Sensortec - Part Type: Sensor - Datasheet URL: https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bme280-ds002.pdf **Pins:** - CSB [pin 2] - GND [pin 7] - GND [pin 1] - MISO [pin 5] - MOSI [pin 3] - SCK [pin 4] - VDD [pin 8] - VDDIO [pin 6] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/markwuflux/environmental-data-logger-copilot-v2-example-project~de](https://www.flux.ai/markwuflux/environmental-data-logger-copilot-v2-example-project~de).* --- *Generated from [https://www.flux.ai/markwuflux/environmental-data-logger-copilot-v2-example-project~de](https://www.flux.ai/markwuflux/environmental-data-logger-copilot-v2-example-project~de)*
