This is a derivative of my original Breadboard Project Box with a few key modifications:

• Removed battery holding area
• Added side "channels" to hold cellular antenna
• Corner channels for battery wires

This box holds a half-size breadboard with a Particle Electron on top and has enough room below to hold the battery, a short micro USB cable, and some jumper wires. Everything you need to help make your project more mobile since you can now work on it anywhere that has cellular reception!
