A general purpose 40 pin 8051 evaluation board with just the bare essentials required for using a 8051 microcontroller - port extentions, crystal circuit, reset switch, power status and a general purpose LED. This board is perfect for building rapid prototypes and projects. The board provides port extensions for all ports and also provides an empty hole for each IO, where wires and connectors can [..]

It is a low-cost 2.4GHz transceiver designed for very low-power wireless applications. It can be used in 2400-2483.5MHz ISM/SRD band systems, Consumer Electronics, Wirelessgame controllers, Wireless audio wireless Mouse and others wirelesssystems.

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-232 side is a 9-pin female connector. if the board[..]
