Welcome to mt32-pi | zero, the first piece of official mt32-pi hardware directly from the creator of the software! 🎹 Build your own standalone MIDI synthesizer based on the Raspberry Pi Zero 2 W. 💾 Supported by the open-source mt32-pi project, providing Roland MT-32 and SoundFont-based synthesizer engines. 🔊 TRS Type A MIDI in, 3.5mm stereo audio out via. hi-fi PCM5102 DAC. ✨ 128x64px OLED, two control buttons, and a unique jog wheel for volume control. 🕹️ MiSTer FPGA compatible, using a standard SHORT (<30cm) USB 3.0 to micro-B cable (as found on portable hard disks). What's included: ✅ Main PCB ✅ Top faceplate in MATTE BLACK (GLOSSY WHITE is available on request, send a message via Ko-fi as soon as possible after ordering!) ✅ Bottom aluminium faceplate ✅ 8x screws, 4x brass standoffs ✅ Self-adhesive heatsink for Raspberry Pi Zero 2 W ✅ Thermal pad ✅ Braided lanyard ✅ Official mt32-pi small holographic sticker What's NOT included: ❌ 3D printed case (sold separately HERE: 👉 ko-fi.com/s/3f316bf325) ❌ Raspberry Pi or SD card 👉 DON'T FORGET YOUR CASE: ko-fi.com/s/3f316bf325 👉 A Raspberry Pi Zero 2 W with soldered 20x2 GPIO header is REQUIRED. Find one here: rpilocator.com 👉 Want to use it with real MIDI gear? Add a MIDI DIN to TRS MIDI cable here: ko-fi.com/s/7d86bdc0d8 👉 MiSTer FPGA user? Add a compatible USB cable here: ko-fi.com/s/dbe6dfe7bc 👉 Want to 3D print your own case?

However... ⚠️ All PCBs feature a space for an LTC4311 I²C signal booster chip to be soldered onto the board. This is an experimental option which MAY allow longer cables to be used with MiSTer FPGA (>50cm). Above-average soldering skills required if you want to try this! ⚠️ The I²C signal booster is NOT REQUIRED for long MIDI IN cables; this only applies to MiSTer FPGA users who want to try long cables. ⚠️ Additional cable length enabled by the chip is not known (yet) nor guaranteed. ⚠️ Short (<30cm) USB cables such as the ones sold here DO NOT require the signal booster. 🚫 Strictly one PCB kit per customer. Multiple PCB kit orders from the same person may be cancelled. 📖 PDF manual available here: drive.google.com/file/d/1diaTFURAc2TzwEeXZUTabSlbScPvL31C/view
