BSerial – SYNTH is a powerful general MIDI-compliant synthesizer designed to deliver high-quality audio in an ultra-compact package. Measuring just 26mm x 23mm, it integrates seamlessly with your projects, offering exceptional sound quality, versatile connectivity, and advanced features powered by the SAM2695 chipset.
Connecting the module to your system takes only seconds via the Bi2C port, and gives you instant general MIDI functionality!
You will need a Challenger board with a BSerial/Bi2C connection to use this board.
What is BSerial?
BSerial is a part of iLabs concept (BConnect that spans over Bi2C, BSerial and BSpi) of connecting devices together using a small Flexible Flat Cable (FFC) and an FFC connector. It is similar to the Bi2C concept but we have replaced the electrical I2C interface with an asynchronous serial channel instead. You can read more about it here.

A short Arduino example showing how to build a simple MIDI player that plays MIDI files from an SD Card. This demo was built on the Challenger RP2040 SD/RTC board and the example is taken from the MD_MIDIFile library and modified slightly to run on the Challenger.
