Hi there, I’ve read your brief and can deliver this Teensy 4.1–based expander quickly and reliably. I’m a mechatronics/PCB engineer (~5 years) with deep experience in audio/MIDI electronics, complex mixed-signal layouts, and firmware bring-up. I’ve already worked with all components and interfaces you listed: Teensy 4.1, DIN/TRS MIDI I/O, CH334 USB 2.0 hub, SPI TFTs (incl. touch), MicroSD switching, SK6805 RGB button grids, addressable LED strips, DMX, Bluetooth modules, rotary encoders (mouse), IR, I²C GPIO expanders, TXB0108 level shifting, and MOSFET power switching. Approach (concise): Architecture & power plan (rails, EMI/grounding) for main + two 10-channel button/LED PCBs + MicroSD board. High-speed/low-noise routing (SPI fan-out to 11 TFTs, SD mux, USB, MIDI/DMX isolation), with stable memory handling and interference avoidance. Fabrication package (Gerbers, PnP, assembly notes) and test firmware to validate every peripheral. Happy to sign LOI/NDA and review your 170-page spec. Send me a message and I’ll share a short milestone plan and get started right away. Best regards, Samuel tshibangu
