These~ products can substitute the original. Be careful, 3.3V products can be used here. Some of clones are 5V, and the~ 5V clones cannot be applicable here.~ > - How to Make > 1. '''MAX3232''' is placed on the breakout. The square-land (U1) indicates the location, where the first pin of IC~ is placed.~ &ref(30pinbkout64x48.jpg,,25%);~ ~ 2. Five Multilayer Ceramic Capacitors are put into the breakout.~ At each location, there are one square-land and two round-lands, and it requires only one square-land and one~ round-land. A round-land can be selected depending on a shape of capacitor. If use a 2.5mm-multilayer ceramic~ capacitor, choose the round-land next to the square-land. As using a 5 mm-capacitor, skip one round-land and~ apply the far side round-one. This makes ceramic capacitors apply to the breakout effortlessly and smoothly.~ &ref(CIMG8702n.JPG,,25%);~ ~ 3. Apply DSub 9-pin connector.~ ~ 4 Place 30 pin headers. Remove the 17th-pin. (Please see the picture 4)~ &ref(CIMG8711n.JPG,,25%);~ This is the end of working on the breakout.~ ~ 5 Make a cable. Connect a four-wire cable to 30-pin iPod connector. Use only four terminals of 30-pin iPod~ Connector. #11, #12, #13, and #18 terminals are connected to black, white, green, red cables, respectively.~ |terminal|Wire Color| |11|black| |12|white| |13|green| |18|red| &ref(CIMG8705.JPG,,25%);~ ~ 6. On the other side of cable, small signal contacts are attached.~ &ref(CIMG8733.JPG,,25%);~ ~ 7.The small signal contacts are inserted into the small signal connector housing. The wires, which are connected~ to #11, #12, #13, and #18 of 30-pin iPod connector, are linked to #1, #2, #3, #8 of terminals of the small signal~ connector housing, correspondingly.~ &ref(CIMG8729.JPG,,25%); &ref(CIMG8730.JPG,,25%);~ The small signal connector housing is 4x2 and has 8 terminals. These terminals are connected to #11, #12, #13,~ and #18 pins of pin headers on the breakout, respectively. If the wires are too thin, the small signal contacts~ could not hold wires well. Please change the wires more thicker than the the originals.~ could not hold wires well. Please change the wires more thicker than the the originals.~ &ref(CIMG8731.JPG,,25%);~ ** How to Use [#m798d3b5] > -- Connect the cable created above to the 30-pin connector at bc10. The 30-pin iPod connector is attached to the 30-pin~ connector of bc10. -- Connect the small signal connector (4x2, 8 terminals) to #11~18 pins of the pin header on the breakout. To turn the black~ wire (#1, connected to #11 pin) toward #1 pin side, make sure that red wire (#3, connected to #12 pin) is put next to the~ black one. -- Attach a relay cable at the side of Connect Dsub 9-pin. Connect the cable to RS232C. At the other side, connect to a serial port~ of a PC. ** Memo [#p706415b] > - This example uses only the serial console communication function of this breakout. This breakout is capable of handling other signals and~ can be equipped with other functions. -- USER button -- RESET button -- Power supply switch -- Stereo Audio input/output -- Video/S-Video output * Revision History [#p1a800a3] > - 2010/11/10 This article is initially uploaded. - 2010/11/12 Add more pictures.
