Cheap, stable-flying, and easy-to-modify. Whistles while it flies, which is cool.

MPU6050 digital accel-gyro
These chips can measure up to 16 g's of acceleration in each axis. They communicate with the NodeMCU over I2C around 200 times a second. We didn't use the gyroscope data in this project, as we expected the football to spin faster than the gyro could measure.

DROK brand buck converter chip
These little chips are great! It's a thumbnail-size switching regulator that can step down 4.5-24 volts to 0.8-17 volts at up to 3 amps without breaking a sweat! Pinout is the same as a linear regulator, sans filter capacitors.
