I bought a "40MHZ DDS FUNCTION SIGNAL GENERATOR DIY KIT SPI I2C MASTER SLAVE PULSE GENERATOR" on ebay:
http://www.ebay.com/itm/111149124406But I got none of the promised assembly documents for the kit (see complete details in "Buy/Sell/Wanted ยป The Bad Shopping Experience Thread")
And, at this point the seller appears to be so flaky, my expectation of receiving the documents from him is asymptotically approaching zero.
Anybody have these docs or know somebody who has them?
