Over the past year and since I published my initial mailbox notifier project, I've been asked by various people if I could build a standalone receiver for the Moteino network of things. Some people wanted just an LED to light up when a certain packet is received (like the mailbox was opened), others wanted an LCD to see the entire message and battery level, or other things like that. I kept wanting to get to this, however I was always too busy but kept juggling the idea in my mind.

At the same time I wanted to have a better MotionMote solution (also featured on HAD). One that would be chargeable and programmable through USB. This could be used as mailbox notifier, or as motion detector.

So the past few weeks I've been working on revisions of a combination of the above: a motion detector and standalone Moteino receiver with LED and OLED screen. The result is below (I will need to make a nice case for the receiver):

This combined PCB can accept a standard PIR sensor, or a typical I2C

SSD1306 OLED screen to create dual functionality. It can be a motion detector (or mailbox notifier), or a receiver for the motion/mailbox message, or of course a receiver for any of your Moteino framework(s). Just charge and program it over USB. It will take a 1000mAh battery which should fit nicely under the PCB and into the lasercut acrylic case, and should provide many months of runtime as a motion sensor, and probably a day or two as an OLED receiver.
