Unoq hat
About the Unoq hat
Unoq hat is an open source PCB design by Leif-Rydenfalk, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 68.6 × 53.3 mm, with 77 components from 45 distinct parts.
Other key parts include the TCA9406DCUR, TCA9555PWR, TPS62933DRLR, PAM8302AASCR and SN74LVC1G126DBVR. By type, the board carries 27 resistors, 24 capacitors, 12 connectors, 9 ICs, 2 transistors and 1 fuse.
It belongs with the robotics & motion, dev boards & breakouts 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.
