Supports Microchip's full suite of development applications

This board ships with the headers uninstalled. They can be installed from the bottom or the top, to allow for usage with a standard breadboard.

NOTE: BM83 part numbers will vary according to availability. The modules are all the same except for the default firmware that comes on them from the factory. For example, part number BM83SM1-00TA comes with latest AT v1.0 firmware by default.

All modules will be flashed with the latest (ver 1.30) Multi-Speaker firmware for testing but can easily be flashed with any Microchip firmware designed for the BM83. Firmware update can be performed via a standard USB-Serial adapter or by wiring up a USB breakout module.

If you would like a specific firmware flashed to the module prior to shipping please let me know in the order notes.
