Total Price:
$6.30
For use with USB to VGA adapters and Osmo-fl2k.
The RED “transmit” pin from the adapter is broken out to an SMA connector. The +5V pin is used to drive an optional power LED. The Cable Detect pins are broken out to solder jumpers to connect them to ground. Cable detect is taken care of in software so these are not currently needed, but I broke them out just in case.
This board does not provide impedance matching, attenuation or filtering. It is merely an SMA breakout.
Bill of Materials:
- VGA Connector: DSUB HD15 Right Angle (Digikey PN# A31927-ND)
- SMA Connector: Edge launch SMA for .062" PCB (Digikey PN# CON-SMA-EDGE-S-ND)
- Power LED: 0805 (optional)
- R1: 0805 470Ω to 1kΩ (optional)
