eBay Find

I bought two of these boards off eBay for $10. Like an idiot I didn’t notice the seller had ‘make an offer’ enabled; I’d have bought more and probably paid less. I’m interested in the DAC and a couple other parts. Too bad that Spartan is a BGA, since I don’t have any reballing equipment.

I’d love to know what they were originally for. Have any idea? There’s an Analog Devices AD9761 TxDAC, so that leads me to believe the board was used for some RF purpose. But there’s no RF connectors, so I could be wrong.

    Acknowledges for this worthy ratio. I ordered pair of these commissions eccentric eBay. Cherish an dunce I didn’t observe the merchant had ‘make an invitation’ enabled; I’d acquire ordered extra moreover presumably paid inferior. I am involved in the DAC further a pair else units.
