Here is a table listing all the pins of component J1:

Table

Pin NumberPin NameFunction
1Pin_1MISO connection (Net: Net 4)
2Pin_25V supply (Net: Net 2)
3Pin_3SCK connection (Net: Net 1)
4Pin_4MOSI connection (Net: Net 14)
5Pin_5RESET connection (Net: Net 26)
6Pin_6Ground (Net: GND)
And here are the specific connections associated with each pin:
  • Pin 1: Connects to MISO and U1 (PB3_PDO_/_MISO_/_PCINT3)(PB3\_PDO\_/\_MISO\_/\_PCINT3).
  • Pin 2: Connects to multiple 5V sources in the circuit, including U2 (VBUS)(VBUS), R3, and other instances of 5V.
  • Pin 3: Connects to SCK and U1 (SCLK_/_PCINT1_PB1)(SCLK\_/\_PCINT1\_PB1).
  • Pin 4: Connects to MOSI and U1 (PDI_/_MOSI_/_PCINT2_PB2)(PDI\_/\_MOSI\_/\_PCINT2\_PB2).
  • Pin 5: Connects to RESET, SW5, R8, and U1 (RESET∗PC1_/_dW)(RESET*PC1\_/\_dW).
  • Pin 6: Connects to the ground net, shared with multiple ground connections in the circuit including U1, SW5, and other components.

To replace U2, which is a Molex micro-USB connector with MPN 1050170001, you can consider the following alternatives:
  1. TE Connectivity 1734035-3
    • It's a similar micro-USB type B receptacle.
    • Cost-effective and reliable.
  2. Amphenol FCI 10118194-0001LF
    • Another micro-USB connector with similar specifications.
    • Known for its durability and availability.
  3. Hirose Electric UX60-MB-5S8
    • A high-quality micro-USB type B connector.
    • Slightly more expensive but offers robust performance.
When selecting a replacement, make sure to check the mechanical dimensions and pin configuration to ensure compatibility with your PCB layout. If you have any specific requirements, such as current rating or footprint constraints, let me know!
