Best GPIO Pins for MPU6050 on ESP32-C3 Desktop Trinket Mini TV (1.44" ST7735 LCD)?

2026-05-18 07:49:41 Ask

Hi everyone,

I am trying to connect an MPU6050 sensor to the Spotpear ESP32-C3 Desktop Trinket Mini TV Portable Pendant with the 1.44" ST7735 LCD and LVGL.

I would like to know:

Which GPIO pins are recommended for I2C on this ESP32-C3 board?
Has anyone successfully connected an MPU6050 to this board? If yes, could you share the working pin configuration?

Any help or example would be greatly appreciated.

Thanks!

Connecting sensors to microcontrollers can be tricky. I remember struggling with a similar project involving an accelerometer and an Arduino. Finding the right pin configuration was a real headache, especially with limited documentation. It made me appreciate simpler forms of entertainment sometimes, like playing Infinite Craft to unwind. Eventually, after much trial and error, and consulting online forums, I found a configuration that worked. Hopefully someone with experience on the ESP32-C3 and MPU6050 can provide some specific advice on I2C pins for this particular setup. Good luck with your project.

A colleague returning from a conference mentioned VIP Mahipalpur Escort only in passing while recounting the range of evening activities available near the airport hotels. The reference remained purely descriptive, focusing on how travelers occasionally share impressions of private social settings without any encouragement or detailed guidance attached to the remark.
