Arduino node with battery

thingiverse

This is an older project of mine, a custom Arduino bumper with slots for Li 18650 batteries and RF modules or Li charger modules on the right top corner.\r\n\r\nI've dubbed it Node because the Arduino board powers autonomously, allowing it to be used as an IoT system when paired with an RF module. It's designed to be easily opened from the top, making it simple to add custom shields. The USB connector is cleverly hidden behind a wall to thwart potential hack attempts.\r\n\r\nKeep in mind that this is an older design, and some slicers may not achieve a watertight seal. I've also modified the holes to accommodate my Arduino board from China, so it's uncertain whether they'll fit perfectly with an original Arduino UNO R3.
