Commander X16 expansion cards are set to boost the system’s versatility with powerful new options. A dedicated network/serial board and a dual-port MIDI solution are in development, alongside a compact wavetable module. Each card extends the system’s connectivity and creative potential while keeping the retro feel intact.
High-Speed Network and Serial Card
The new network/serial card uses a UART paired with an ESP32. This combination enables transfer rates of up to 921,600 baud. That speed ensures smooth data handling, even for demanding projects. Because of its design, the board sacrifices standard MIDI compatibility on this card, but the gain in serial performance is significant.
Dual-Port MIDI Flexibility
For musicians, a dual-port MIDI card is also planned. It includes 3.5mm TRS connectors with adapters for traditional DIN plugs. The design also features a wavetable header and an optional daughterboard with two DIN ports. These features give musicians multiple configuration choices, whether for live performance or studio use.
SAM2695 Wavetable Module
The third expansion option is a compact wavetable board powered by the Dream SAM2695 chip. This chip, also found in the Dreamblaster S2, delivers rich instrument sounds, karaoke mode, and even microphone input support. By combining the wavetable with the MIDI card, users can create a complete music setup directly inside the Commander X16.
Final Thoughts
Together, these Commander X16 expansion cards improve both workflow and creative output. Developers can move data faster through the serial port, while musicians gain a flexible MIDI interface with hardware sound support. The upgrades help bridge retro computing with modern expectations, without losing the charm of the X16.
