Interface Boards
This small board has been designed to convert TTL (Transistor-Transistor Logic) level signals to RS-232 interface and vice versa. This allows the user to develop applications so that the board will act as an intermediate for the communication between the two devices that follows TTL and RS-232 standard. The TTL side is a 4-pin connector and the RS-[..]
