About the TB6612FNG PCB

TB6612FNG is an open source PCB design by SohumNigam, published on GitHub. It is a 2-layer board measuring 25.5 × 29 mm, with 7 components from 5 distinct parts.

Other key parts include the TB6612FNG. By type, the board carries 4 capacitors, 2 connectors and 1 IC.

It belongs with the robotics & motion and sensors designs in this gallery.

From the project

A self-balancing two-wheeled robot. an inverted pendulum stabilized by IMU feedback and PID motor control, being built up toward full 4-state LQR control on a custom PCB.

Full write-up / showcase: sohumnigam.github.io/projects/stabilitybotMK1.html

I wanted a project that went past the usual "balance a robot with a PID loop" hobby build. Something that let me go deep on control theory (state-space modeling, LQR, Kalman filtering), embedded firmware, and PCB design all at once. The long-term goal is a robot that balances using a full 4-state LQR controller (θ, θ̇, x, ẋ) on hardware I designed…
