System Power Monitoring
R1000AX includes an INA3221 high side supply monitor from TI. It monitors the high voltage, 5V and 3.3V domains.
| INA3221 Channel # | Voltage Domain | Operating Range |
|---|---|---|
| 1 | High voltage | 9 ~ 24V |
| 2 | +5V | 4.5v~5.5V |
| 3 | +3.3V | 3V~3.6V |
EEPROM For Storing NV Configuration Data
R1000AX includes a small 8kbit EEPROM that can be used to store critical configuration data outside the MCU flash memory. This is useful for tracking changes, serial number ... etc. By default the EEPROM is write protected, the user enable write by 2 ways
| Short J18 with a jumper |
|
| Connect TP1 on the bottom of the board to ground. This is useful for automated test setups |
