We will use a few components to build our Boxing Glove tracker:

1 x ESP32-S3 with a TFT display

1 x ADXL345 accelerometer

1 x Lithium-ion 3.7 volt battery

ESP32-S3 TFT display

The ESP32-S3 TFT will serve as the brain of the project, collecting data from the accelerometer and displaying it for visualization on the TFT display.

The TFT display will display the data from the accelerometer, battery percentage, and if the board is connected to the internet.

ADXL345 Accelerometer

The ADXL345 accelerometer will be used to measure the acceleration and impact of the glove.

The accelerometer measures the acceleration of the gloves in all three dimensions (x, y, and z). This information can then be used to track the movement and impact of the gloves.

This accelerometer comes with STEMMA QT connectors so that we can plug the accelerometer into the ESP32-S2 TFT with a STEMMA QT / Qwiic JST SH 4-pin Cable.


This project uses a thin and light Lithium Ion 3.7 volt battery to power the ESP32-S2 TFT board. I've decided to use this because it was easier to fit into the glove and prevented tearing the glove's leather.
