Overview

Encoderboard is an open-source printed circuit board by SSL-A-Team, from the SSL-A-Team/electrical repository on GitHub, published under the MIT licence. It is a 2-layer board of 64 × 10 mm with 14 parts on 12 nets, routed with 85 tracks and 18 vias.

It is built around the AS5047P-AT and SM06B-SRSS-TB. Its parts include 3 resistors, 2 capacitors, 2 connectors and 1 IC.

Getting Started with A-Team Electrical

All current board releases use KiCad 7.X.

See releases for competition production files. Our releases include known bug documentation, and the confirmed gerber, BoM, and CPL files sent to fab so you know you're looking and ordering what we did. Releases are accompanied by a tagged commit, for all editable project files used to generate the fab products.

For complex boards like control and kicker, we include spice models and python files that compute any relevant values from datasheets, and including documented references and links to needed formulations.

Setting Up KiCAD

Setting Up the KiCAD Library Path

Click Preferences->Configure Paths
Under Environment Variables click +
Set the name LIB_DIR_AT
Set the path to <repository_location>/lib where <repository_location> is the download location.

Example entry:

Name: LIB_DIR_AT
Path: C:\Users\guyfl\Documents\A-Team\electrical\lib

Setting Up JLCPCB Plugin

KiCAD version 6.99 (nightly) or newer should install the KiCAD JLCPCB Tools plugin.

Setting Up the Python Environment

We recommend creating a python environment using python3 -m venv venv (python 10 appears to be required)
Install poetry pip install poetry
Run any python file with poetry run python <python_file>
(Optional) Add dependencies with poetry add <dependency>

Soldering

Our soldering process is documented. Advanced components like modern SMPS chips and current sense motor hardware proved sensitive to technique. The team's tries to PCBA as much as possible, but sometime it's too expensive to PCBA all chips, especially advanced ones not in stock at the fab house.

Questions

How big is the Encoderboard PCB?

It measures 64 × 10 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Encoderboard use?

14 parts, built around the AS5047P-AT and SM06B-SRSS-TB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Encoderboard KiCad files?

From the SSL-A-Team/electrical repository on GitHub, at the commit this page was made from: the board is robot/encoderboard/v1.1.0/encoderboard/encoderboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Encoderboard design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
