These are simple level shifters and a DC-DC cconverter that enables a PS/2 Mouse or Keyboard to be connected to the nRF24LU1. The PS/2 Adapter connects to the “ISP Interface” connector on the BFB. This setup is intended to emulate a wireless mouse or keyboard using existing devices. The schematic and layout for the PS/2 Adapter is shown in Figure 18 and Figure 19. The BOM is in Table 5. The PS/2 is a bi-directional synchronous link, with one data line and one clock line. The power supply and the logic levels are 5v TTL. To interface this to the nRF24LU1, the PS/2 adapter is used. The DC-DC converter is a MAX619 3v to 5v IC. Revision 1.0 Page 28 of 36

nRF24LU1 Development Kit User Guide The level shifter is made by resistors and a transistor. Since it is difficult to use a level shifter in a bidirectional data line, the signal is split on the MCU side, so that the input and output are on two different IO’s.
