            |   | 46 |  * Add optional load resistors to pins 11 & 13 of Mini-PCIe slot J10 for optional modem compatibility | 
          
          
            |   | 47 |  * Update TVS diode to bidirectional and move on connector side of reverse protection diode.  | 
          
          
            |   | 48 |  * Replace PCIe to GbE bridge LAN7430 to 88E8057 due to supply chain availability | 
          
          
            |   | 49 |  * Update J5 & J11 silkscreen  | 
          
          
            |   | 50 |  * Add optional load resistors to route UART1 TX & RX to J5 as an alternative to Analog1 & 2 | 
          
          
            |   | 51 |  * Replace PoE diodes with different mechanical size due to supply chain availibility | 
          
          
            |   | 52 |  * Do not load certain capacitors as per the RGMII Phy datasheet. |
