| + | |||
| + | * In v1 USB can be added with a MOD. | ||
| + | * In v2 USB is present but no pinouts are available on PCB to solder USB socket. | ||
| + | |||
| + | For the v1 USB mod you need to solder wires to the following resistors: R100 (Pin 73) and R101 (Pin 74). | ||
| + | The side that is soldered is facing the LED'S. The side facing the RJ45 jack is ground. | ||
| + | I recommend using a thin gauge wire so as not to detach the resistors. | ||
| + | You can solder directly to the CPU but i recommend you solder directly to the back of the above resistors as this is easier. (Please remember to orientate your board correctly.) | ||
| + | A 5 Volt regulator is also needed to power the USB port.(You can add a filter capacitor.) | ||
| + | You will not need to add any additional resistors. | ||
| + | I do not recommend using the USB port with the PoE unless you upgrade the power supply. | ||
| + | The way the USB port has been powered will only work when the power supply is plugged directly into the access point. | ||
| + | |||
| + | ==== Standard Passive POE Voltage Hack ==== | ||
| + | The TP-Link TL-WA701ND and other TP-Link AP devices do not support standard passive POE voltage (48V) but instead they supports an unusual 9V or 12V DC input. If you plug the AP in a standard passive POE injector at 48V this results in damaging the capacitors and ultimately shorting out the board. If this happens and you have a decent brick power supply, it limits the output current and you save the board, otherwise the board could be damaged irreversibly. | ||
| + | You can easily circumvent this limitation by replacing the electrolytic capacitors on the board with the appropriate ones rated at least 63V. Replacing them is pretty straightforward, | ||
