Finished searching for components.

I can’t add parts into this template directly because you don’t have edit access here, but these are solid picks:
  • Temperature sensor: MCP9808-E/MS
  • 8x8 charlieplexed LED driver/display option: IS31FL3731-QFLS2-TR
The library search found MCP9808-E/MS as a strong I2C temperature-sensor choice, and it identified IS31FL3731-QFLS2-TR as the best fit for a charlieplexed LED matrix style solution . The external search also confirms the IS31FL3731 is a 16x9 Charlieplexed PWM LED Driver, so it can comfortably handle an 8x8 display arrangement
Here’s a link to start a new editable project with those parts as the design intent: Create new project
If you want, I can also give you:
  • a cheaper option
  • an Arduino-focused option
  • a version with a bare 8x8 LED matrix instead of just the driver
Arduino-focused option

    Template for Arduino Uno R3 Shield. Include an official pinout so you will always know Arduino names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Arduino Uno R3 itself along with the board outline on the silkscreen. #Arduino #Uno #Shield #Template #project-template #project
