Overview
Daisy hc165 is an open-source printed circuit board by gcask, from the gcask/the-pit repository on GitHub, published under the MPL-2.0 licence. It is a 2-layer board of 44 × 55 mm with 12 parts on 15 nets, routed with 70 tracks and 10 vias.
It is built around the 74HC165D, 4D03WGJ0103T5E and CL05B104KO5NNN. Its parts include 4 connectors, 1 capacitor and 1 IC. It belongs with the keyboards and input boards of this library.

README
README.mdThe Pit
Simple arduino-based gamepad to connect custom switches and toggles and easily bind into DCS (uses standard mappings, nothing fancy).
Supports hundreds of switches on a single arduino board.
Relies on HC165N Parallel-Load Shift Registers, which are inexpensive ICs, to achieve a high number of inputs.
Firmware
Arduino-based program to manage a Sim Pit efficiently. The code is setup to be able to handle hundreds of inputs over a single Arduino chip, via the use of shift registers and SPI.
The recommended and target board is Leonardo.
Setup
- Download and install Arduino IDE v2
- Copy the
firmware/hardwarefolder to your local Arduino install, ie%USERPROFILE%/Documents/Arduino/.- In the end, you should have a
%USERPROFILE%/Documents/Arduino/hardware/thepit/avr/boards.txtfile. - You can verify it works if your Arduino can locate a
The Pit (Leonardo)board.
- In the end, you should have a
Uploading
Because the software is trying to maximize available inputs, it eats up the endpoints that are used to upload a sketch any time.
Reset the board during the Upload... phase, otherwise it will fail.
Customizing
Customizable values, such as the number of daisy-chained hc165, how many gamepads we're emulating, etc, are available in thepitconfig.user.h.
Hardware
Daisy-chained hc165 Board
A simple board to easily daisy-chain several hc165 together. Each board has 4 connectors:
- 1x daisy chain in, that you connect from the out of the previous board (or from the arduino board)
- 1x daisy chain out, that you connect to the in of the next board (or to the receiving end of the arduino board)
- 2x inputs, each with 4x inputs and 1x ground, that you connect to your switches (pull-up logic, integrated to the board).
Wiring
Pin 5 is used to latch the hc165, use the ICSP pins for SPI communication. On the board, the pins from the connector are labeled with their usage:
- Vcc: 5V in
- GND: Ground
- ~PL: Pulse Latch (Pin 5)
- CP: Clock Pulse (SCK, pin 3 on the ICSP)
- DS: Data Serial in (for daisy chain in) (COPI, pin 4 on the ICSP for the first in the chain)
- Q7: Data serial out (for daisy chain out) (CIPO, pin 1 on the ICSP for the last in the chain)

Questions
How big is the Daisy hc165 PCB?
It measures 44 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Daisy hc165 use?
12 parts, built around the 74HC165D, 4D03WGJ0103T5E and CL05B104KO5NNN. 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 Daisy hc165 KiCad files?
From the gcask/the-pit repository on GitHub, at the commit this page was made from: the board is hardware/daisy_hc165/daisy_hc165.kicad_pcb and its schematic hardware/daisy_hc165/daisy_hc165.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Daisy hc165 design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
