-The echo module ​based on the digital delay chip PT2399. + 
-{{ :​paper_bits:​sideviewmic.jpg?​nolink ​|}}+PB401 VC Echo is the echo and delay module ​for the [[paper_bits:​paper_bits_main|Paper-Bits]]\\ 
 +It isbased ​on the digital delay chip [[http://​www.princeton.com.tw/​Portals/​0/​Product/​PT2399_1.pdf|PT2399]]The amount of echo could be changed with a potientiometer. The length of the delay could be adjusted with a 5V control voltage ​ (0 to 5V) optional with a potientiometer, ​ too. This could be set with a jumper. \\ 
 +The board was developed by Wolfgang Spahn in 2017. With the friendly support of his intern at that time [[http://​ioanavrememoser.com| Ioana Vreme Moser]].\\
