@stan2004 posted:Of course I'm obsessed with the possibility of a 2-wire self-powered PS2 version. To that end I reduced the 470uF cap to 220uF as you have in your size-matters module.
What is the actual diagram of what you have working there? It would seem it would be very simple to make a tiny board plug the transmitter module into.
I was looking at the components to do the transmission without their board, where did you find this little board? Adding the 8-pin chip and this board is all it would take to transmit the data, a very compact board. In truth, making the transmitter with our power requirements wrapped around it would be simple if the components and spec sheets were available.
