 All right, lady, what is this? Hey, I'm testing out some prototypes I just put together. This is an MCP 23017 breakout. And people have actually even emailed us asking to make a breakout for this chip for quite a while. And I've always been like, well, just use the dip chip. But I can see why some people would want a version that's a plug-and-play and STEMI QT. So it's got the MCP 23017, 16-bit IO expander. And then we have eight ground pads on either side. Address jumpers on the back, STEMI QT plug-and-play connector. And here, I'm just testing it out with a simple blank using an LED. And it works great over I2C. It is a nice GPIO expander. It has pull-ups and interrupts and all that. So this looks like it's working fine. I'm going to order these and get them into the shop soon.
