Behind the board there are 2 expoied over chips marked U3 and U4 On the main board the connections run VCC, CLK, SCL, SCA L-, L+, RST, GND Still - it be nice to know IF they do work the same as it will save troubleshooting later if something does not work. Many thanks Marc Hi Stephen

VCC, CLK, SCL, SCA
L-, L+, RST, GND

Still – it be nice to know IF they do work the same as it will save troubleshooting later if something does not work.

Many thanks

If so then I’m pretty sure they still work.

Sparkfun has a very handle Logic Level Convertor that I have seen people use. Now.. I need some help and I am willing to pay for it. I have on my desk 3 WII remotes (2 supposed genuine) , all disassembled, and NONE of them has the Pixart sensor in it. I am beginning to think that the Australian model does not use it. All of the sensors are small boards. You seem to be able to get the units with the Pixart module in it. Can you help.. Many thanks Marc Hi Stephen

Check out the MIDI Camera in cool toys - this version uses mosfets and diodes to do all the level conversion between the 5v Arduino and the 3.3v Pixart sensor. Steve Hi Marc,

Many many thanks for your article. I am finding that the LTC4301 chip is very difficult to find. I have seen that Sparkfun have a Logic Level Convertor that will work on I2C busses. What your viewpoint on this? Is this a good alternative? Many many thanks for any information Marc Hi Stephen.

I've been working on an update to this project this month - should have something ready at the end of the month. Sasha – stay tuned.

I am trying to do the same but i have diffrent connections on the IR camera, from wii remote (2010). Have you ever seen diffrent connections? Can you give me some advise please. Thanks Sasha Hi,

Helped me follow in the footsteps of great hackers, such as yourself and others, and interface the pixart camera with an ARM-based mbed MCU (a much easier task; it's a 3.3v device and it can generate the 20MHz clock signal all by itself). -Michael Thanks for the series of articles on this.
