Looking for Feedback on PICaxe Platform Module
March 18, 2010
I've been working a PICaxe platform module. I did a V1 a few months ago, and recently re-did it. Here's a prototype of V2;
I've used the same power stage as the Propeller Platform sD - it's 5v @ 1.5A and 3.3v @1.5A with an extremely low dropout of 100mV. Standard power and programming jack, and it has power indicator lights.
I need to make a few changes, so I thought I'd get additional feedback.
1 - Platform Modules expect 32 GP I/O, but no PICaxe's have that much. My current thinking is to let the user jumper PICaxe I/O to the Platform connections. I don't want to do a complicated I/O expander IC and removable Jumper shunts would get very complicated and messy.
Is that the best route?
2 - Right now, I'm targeting a 20X2. It's pretty powerful, but still inexpensive. The connections will also support M series PICaxe's. What do you think of using that one? Is there another PICaxe that would be better (but still inexpensive)?
In general, what do you think? Would it be cool to use Platform Modules with a PICaxe?
