POE Add-on Connector
The POE PD Add-on connector is designed to support the OnLogic ADP122 POE PD add-on module.
Other uses are not supported.
CM4 Headers
The dual-header CM4 connectors support installation of Raspberry Pi CM4 modules. Two mounting
standoffs are included to secure the module.
MCU Update Header
A two-pin header is provided to force the DIO controller into bootloader mode. DIO controller updates
should be performed by this method only when instructed.
3 - Mounting Instructions
For a full set of mounting options and instructions, see the
Drawings.
4 - Power Management
4.1 - Protection Circuitry
Parameter
Nominal operating voltage (Rated DC value of input)
Undervoltage protection trip DC level (system turns off)
Maximum safe DC voltage (system not damaged)
These DC levels specified are the absolute max values for the pins for function and safety of the
system. The protection circuitry allows for brief transient voltages above these levels without the
system turning off or being damaged. A transient voltage suppressor on the power input allows
momentary excursions above stated limits. For input power consumption and current see
Appendix A.
