A KiCAD's revisited version of the Ploopy Nano trackball mouse

🧑‍🦱 Brief introduction

I'm a passionate embedded developer mainly focusing microcontrollers based on RTOS and Linux (Kernel & Yocto) 💻 🐧

I work @BayLibre

👯 Open source contributions

• MbedTLS

  • My contributions
  • Improved support for elliptic curves (EC) acceleration through drivers
  • Improved suport for acceleration of EC based algorithms: ECDH, ECDSA, ECJPAKE
  • Improved suport for acceleration for Ciphers and AEAD algorithms
  • PSASIM simulator for a crypto-client setup

• Zephyr

  • My contributions
  • Crypto (MbedTLS and TF-M) contributor
  • Drivers' development (encoders on STM32 devices)
  • Minor fixes to the log system

• Trampoline RTOS

  • My contributions
  • ICCOM driver on Spider platform (both on G4MH and Cortex-R52)
  • Ethernet driver (Rswitch & SerDes) on Spider platform and LwIP integration for the provided examples

🏠 Personal projects (relevant ones)

• ErgoDash-Low ⌨️

  • It's an improvement of the already existing ErgoDash split keyboard in order to:
    • give it a lower profile
    • use Gatheron low-profile switches instead of the standard profiles ones

• Ploopy-nano Kicad 🖱️

  • It's a remake of the famous Ploopy Nano trackball mouse. Reasons for the remake is to provide schematic and PCB in KiCAD intead of Altium as the original project does.

• DABon FW 📻

  • A portable (i.e. battery powered) radio and MP3 player based on STM32F407
  • It inregrates the Si4684 chip from SiLab in order to be able to receive both FM and DAB
  • It is based on a rather simple custom cooperative OS developed by me

• CarPlayer 🚙📻

  • A buildroot and OrdoidC2 based car stero player
  • https://github.com/valeriosetti/linux-amlogic-v6.1 contains my changes to the mainline Amlogic kernel in order to make it work for my project

👯 I’m looking to collaborate on

• Linux kernel, Yocto and Zephyr developments

Adding buttons

Hi!

This looks interesting!

I was wondering if there is a way to add buttons to this and make a complete trackball unit. I couldn't quite figure that out just by looking at the pcb in kicad.

Thanks!
