XBee with built in ATTiny or 128

See subject!

I’ve love to do some small XBee projects with a SMALL amount of logic onboard. More than the simply high/low sensing of xbee, but only 20 or so lines of code. Stuff like setting a single PWM outout, reading 2-3 inputs and setting 2-3 outputs, etc.

An all in 1 PCB with xbee and an ATTiny or 128 would do this nicely. Seeed has something REALLY close, but it’s propriatary 900mhz stuff and only fits the physical profile/pinout of xbee, it isn’t actually xbee compatible.

I’m looking to do simple sensor array type stuff (an integrated module to turn a light on) with this.
