USB Powering
Most Sereies 2 FPGA Boards can be powered via USB. Whether the bus deliver sufficient current depends form the application the memory usage (RAM and controller take about 1W) and the USB specification.
Whether / how USB powering is supported is listed in the following table
| FPGA Board | Power source selection | comments |
|---|---|---|
| USB-FPGA Module 2.18 | no | USB powering not supported |
| USB-FPGA Module 2.16 | no | USB powering not supported |
| USB-FPGA Module 2.14 | automatically | USB 3.0 delivers sufficient power for small applications including RAM |
| USB-FPGA Module 2.13 | by soldering a 0Ω resistor | not recommended because USB 2.0 usually deliver insufficient power |
| USB-FPGA Module 2.04 | by soldering a 0Ω resistor | USB 2.0 usually deliver insufficient power if RAM is used |
| USB-FPGA Module 2.01 | by jumper | USB 2.0 usually deliver sufficient power |
