Dynashield S3

PCB adapter board for mounting a Waveshare ESP32-S3-Zero underneath, with a Dynamixel XL330 connector on top.

Setup

  1. Download the ESP32-S3-Zero part from SnapEDA
  2. Import the .kicad_sym and .kicad_mod files into KiCad (Preferences → Manage Symbol/Footprint Libraries → Add)
  3. Open dynashield-s3.kicad_sch in KiCad
  4. Add the ESP32-S3-Zero symbol and the B3B-EH-ALFSN connector (from KiCad's built-in Connector library)

Wiring

ESP32-S3-ZeroNetDynamixel Connector
GPIO1 (pin 4, left side)DATAPin 3 (Data)
GPIO2 (pin 5, left side)DATAPin 3 (Data)
5V (pin 1, top left)VDDPin 2 (VDD)
GND (pin 2, top left)GNDPin 1 (GND)

GPIO1 and GPIO2 are tied together on the PCB — they share the same net (DATA) which connects to the Dynamixel's half-duplex data line.

Board layout

The ESP32-S3-Zero mounts on the bottom of the PCB using its castellated hole pads (pins 1 and 2 side — 5V, GND, 3V3, GP1-GP6). The Dynamixel connector sits on the top.

Questions

How big is the Dynasheild PCB?

It measures 25.8 × 17.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Dynasheild use?

4 parts. 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 Dynasheild KiCad files?

From the imandel/tiltybot repository on GitHub, at the commit this page was made from: the board is pcb/dynasheild_tinypico/dynasheild.kicad_pcb and its schematic pcb/dynasheild_tinypico/dynasheild.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dynasheild design in my own project?

Its repository states no licence, so its author keeps all rights: ask imandel before reusing the design.
