CM3-PANEL-7-POE is an enhanced version of the popular CM3-PANEL with a larger set of interfaces.
|CM3-PANEL-U||CM3-PANEL-W||CM3-PANEL-7-POE||Raspberry Pi 3+ with 7 inch display|
|RS485 / RS422 / RS232||no||no||yes||no|
|Safety power down||no||no||yes||no|
|RTC with backup battery||no||no||yes|
|Audio out||no||no||DAC Stereo 384kHz 32bit||PWM 16 bit|
There are two ways to provide the power supply to the CM3-PANEL-7-POE.
The debug port works also without active network but it needs to be activated adding this line in /boot/config.txt file:
and adding this line in /boot/cmdline.txt file:
The default serial speed is 115200,N,8,1. The signal levels are at 3.3 Volt.
An USB to 3V3 serial converter is requested to link this port to your computer.
As serial terminal software it can be used:
The physical interface used is a Max Linear SP335 IC that can be configured alternatively via dip-switch as:
On these pins are also available the power supply lines at 5VDC and 3.3VDC. The signals level of any logic line is 3.3 volt. Don't plug boards with 5 volt line voltage to avoid damage to the Raspberry Pi CM3 module.
A Microchip ATTiny88 microprocessor is mounted on the CM3-Panel-7-POE to monitor and manage the power supply and power safe circuitry.
This chip performs many management tasks including:
For the first factory default firmware programming a ICSP port is available. After that the ATTiny firmware can be changed directly by the Raspberry Pi module.
