MicroMyotis 4ch Breakout unit
This breakout unit is designed for use with the μMyotis SFP-type conditioning unit.
It supplies the necessary power to the SFP enclosure via a 5V USB Type-C port, using a low-noise LDO regulator.
LED indicators allow for quick diagnostics:
- Red indicates the module is powered but no sensor is detected
- Green indicates a sensor is detected
The USB port also provides serial USB communication with the μMyotis for updates, temperature monitoring, DC signal output, and light source monitoring.
