- 1-2 = SYS_5V
- 2-3 = VDD_5V
VDD_5V is the main power supply from the DC input jack. This voltage is not present when the board is powered via USB. The amount of current supplied by this rail is dependent upon the amount of current available. Based on the board design, this rail is limited to 1A per pin from the main board.
The SYS_5V rail is the main rail for the regulators on the main board. When powered from a DC supply or USB, this rail will be 5V. The available current from this rail depends on the current available from the USB and DC external supplies.
- Available current (per pin)
- 1000mA (x2 pins), VDD_5V
- 250mA (x2 pins), SYS_5V
J11 - Write Enable (WE)
- Install for write enable
- Remove for write protect
EEPROM Connections
- The EEPROM connections are on I2C and have on-board pullup resistors.
- The connections are local to the card.
- The EEPROM part number is CAT24C256WI-GT3
