About the View base PCB
View base is an open source PCB design by Konn1nn, published on GitHub under the MIT license. It is a 2-layer board measuring 81.2 × 81.2 mm, with 81 components from 32 distinct parts.
Other key parts include the MT6701-CT, T-Micro32_Plus, CH340C, HX711 and TMC6300. By type, the board carries 29 capacitors, 21 resistors, 9 ICs, 8 diodes, 5 connectors and 2 transistors.
It belongs with the wearables and displays & leds designs in this gallery.
From the project
This repo is to document the recreation of the smartknob and the electrical analysis of its workings.
A brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, making it possible to dynamically create and adjust the feel of detents and endstops.
