MIDI28 Development board
TOP
Development board for the "ML2871 MIDI Sound Generator Adapter Board" Item No. 001485.
For software development and optimal calculation of the sound output filters.
Interfaces such as USB are included. The board is partially assembled with SMD components.
Always set jumper W4 to positions 2-3 (3.80V analog voltage). A different version for a different adapter board is available.
The kit includes the EV board (partially assembled with SMD components), a programmed microcontroller with a sample program,
all components as per the parts list, and the adapter board (Item No. 001485).
Supplied with speaker, different type than pictured. (8R/3W - 70mm x 30mm x 15mm)
With an adapter socket PH2.0, the speaker can be connected to the internal amplifier of the ML2871,
or without an adapter directly to the external amplifier on the board.
Software for the USB to UART interface is not yet included.
Drivers for external flash (e.g. for MIDI files), buttons and drivers for the ML2871 are integrated.
Source files for the sample program will be sent after purchase of the kit.
