Trunk imu
About the Trunk imu PCB
Trunk imu is an open source PCB design by Leif-Rydenfalk, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 18 × 15 mm, with 4 components from 4 distinct parts.
Other key parts include the TCA9406DCUR. By type, the board carries 2 capacitors, 1 IC and 1 connector.
It belongs with the robotics & motion, sensors and audio designs in this gallery.
From the project
Open electronics, firmware and control software for a small two-legged walking robot on the Arduino UNO Q
Two boards. The hat is the one that matters; the IMU breakout is a small extra.
A four-layer hat for the Arduino UNO Q, 68.68 by 53.44 mm, 1.6 mm, ENIG. It sits under the UNO Q on the two 2x30 board-to-board connectors and carries everything the robot needs that the UNO Q does not have.
Everything except the board-to-board headers and the camera connector sits on the bottom side, so nothing fouls the UNO Q above it.
