#69867 I had an OLED 128x64 display and I wanted to see what I could do with it. I found that it fit nicely in a small box that I have. The lithium battery fit nicely in the bottom along with a battery charger. I fit some button switches that I had for a user input. I added a MMA8452 accelerometer that I expect to use for orientation of the text on the display. I have a motor/vibrator that I plan to include in the package. I decided to use a ESP-07 since it was a little smaller than a ESP-12. I would have liked the larger memory of the ESP-12 but I doubt it will be a real problem. I have a 2mm spaced connector on the for programming and maybe external connections if I had an application that needed it.

I have space in the bottom for a second battery if needed although I doubt I would. Or I can fill that space with more stuff but at this point I don't know what else I might want.

As far as applications I have thought as a remote control for ESP power control modules around the house. Or as an email notifier and reader that I could use at work. I don't have a phone that I can use for that purpose. I probably would start with a MQTT notify and display device. This project was about making something small with available parts. I know making a custom board would allow it to be smaller.

What kind of applications could you see for this package?
