A compact wireless macro controller featuring 6 programmable buttons and 3 analog controls. The device will connect to a computer via Bluetooth and run on a rechargeable LiPo battery. The custom PCB will integrate the ESP32, buttons, potentiometers, battery management, USB-C charging, power switch, and status LED.
Wireless Mini Stream Deck kicad is an open-source printed circuit board by Bidoul44, from the Bidoul44/Wireless-Mini-Stream-Deck repository on GitHub. It is a 2-layer board of 110 × 60 mm with 11 parts on 16 nets, routed with 97 tracks and 0 vias.
Its parts include 6 switches, 1 IC and 1 connector. It belongs with the power boards and the ESP32 and RISC-V boards of this library.
A compact wireless macro pad designed and built during Hack Club's Half-Life / PCB Week.
The goal of this project is to create a small and reusable wireless controller for a computer.
The device will feature:
The ESP32-S3 will be mounted as a removable module so it can be reprogrammed and reused in future projects.
The ESP32-S3 reads the six physical buttons and the three potentiometers.
The buttons can be assigned to custom keyboard shortcuts or macros, while the potentiometers can be used as analog controls.
The ESP32-S3 communicates wirelessly with the computer using Bluetooth.
The PCB integrates the controls, power system, battery connection, USB-C charging and the ESP32-S3 module.
The PCB is designed as a compact 2-layer board.
Main components:
The firmware is written for the ESP32-S3.
It will handle:
The firmware is designed to remain reprogrammable so the functions of the controls can be changed later.
The PCB and schematic are designed using KiCad.

It measures 110 × 60 mm and has 2 copper layers, 1.6 mm thick.
11 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.
From the Bidoul44/Wireless-Mini-Stream-Deck repository on GitHub, at the commit this page was made from: the board is hardware/Wireless-Mini-Stream-Deck-kicad.kicad_pcb and its schematic hardware/Wireless-Mini-Stream-Deck-kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Bidoul44 before reusing the design.
