+### Pin-out v1.0
+
+
+<a target="_blank" href={require('/img/osh/surf5/Surf5_1.0_Pinmap.png').default}><img src={require('/img/osh/surf5/Surf5_1.0_Pinmap.png').default} alt="Surf5_PINOUT"/></a>
+
+
+The pins below are fixed functions in surf5
+
+| I/O  | Pin Name | Description                                    |
+| :--: | -------- | ---------------------------------------------- |
+|  O   | PC_15    | Connected to user LED                          |
+|  O   | PC_10    | UART2_TX connected USB to Serial IC            |
+|  I   | PC_11    | UART2_RX connected USB to Serial IC            |
+|  O   | PA_03    | SWCLK connected J3                             |
+|  IO  | PA_04    | SWDIO connected J3                             |
+
+
+Apart from GPIO and ground pins, there are 5 other pins on the main 40-pin interface:
+
+| Pin No. | Pin Name | Description                                                  |
+| ------- | -------- | ------------------------------------------------------------ |
+| PIN40   | VBUS     | Micro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V. |
+| PIN39   | VSYS     | Main system input voltage, which can vary in the allowed range 4.3V to 5.5V, and is used by the on-board LDO to generate the 3.3V . |
+| PIN37   | 3V3_EN   | Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-power Surf5), short this pin low. |
+| PIN36   | 3V3      | Main 3.3V supply to RP2040  and W5100S, generated by the on-board LDO. |
+| PIN30   | RUN      | Reset pin, To reset W7500P, short this pin low.      |
+
+
+
+### Operation Condition
+
+| Item                      | Description                  |
+| ------------------------- | ---------------------------- |
+| Operation Temperature MAX | 70C (including self-heating) |
+| Operation Temperature MIN | 0C                         |
+| VBUS                      | DC 5V (+/- 10%)              |
+| VSYS Min                  | DC 4.3V                      |
+| VSYS Max                  | DC 5.5V                      |
+
+Recommended maximum ambient temperature of operation is 50C.
